Description

Technical Field

[0001] This utility model relates to the field of graphene conductive material extrusion technology, specifically to an extrusion unit for graphene conductive materials. Background Technology

[0002] Graphene conductive materials refer to functional materials developed based on the two-dimensional honeycomb lattice structure (graphene) composed of a single layer of carbon atoms, utilizing its excellent conductivity. Graphene conductive material extrusion units are composite processing equipment specifically designed to uniformly mix graphene with other substrates (such as plastics, resins, etc.) and extrude it into functional particles or filaments, making them particularly suitable for producing conductive composite materials.

[0003] A high-shear dispersion extruder for preparing graphene masterbatch, disclosed in CN206663758U, includes a drive unit, a liquid-phase feeding device, a barrel, a twin-screw extruder inside the barrel, a discharge port, a polymer material feeding port I, and a polymer material feeding port II. A counter-current gear is installed at the feed inlet of the twin-screw between the conventional conveying threads, and a vibration device is installed on the outer part of the barrel where the counter-current gear is located. By using the liquid-phase dispersion device and the vibration device at the front end of the screw, graphite is continuously dispersed into a graphene slurry. The two polymer feeding ports allow the graphene slurry to be dispersed sequentially with high and low melt index polymers, thus continuously dispersing graphene in the polymer materials step by step. This extruder integrates high-shear liquid-phase dispersion and melt dispersion, providing reliable support for the preparation of highly dispersible graphene masterbatch.

[0004] The existing technology has the following shortcomings: When extruding graphene conductive materials, the existing extruder unit cannot easily control the amount of raw material entering the extruder according to the working status of the extruder. This makes it easy for a large amount of graphene conductive material to enter the extruder at one time. The accumulation of raw material will affect the working status of the extruder, and thus affect the extrusion efficiency of the graphene conductive material. Utility Model Content

[0005] The purpose of this invention is to provide an extrusion unit for graphene conductive materials. The unit is driven by a first motor to rotate a rotating shaft. Through the meshing action between the rotating gear and two adjacent movable racks, two movable baffles can be moved relative to or away from each other. This allows for convenient control of the bottom opening size of the hopper, which in turn allows for convenient control of the amount of graphene conductive material fed into the machine. This ensures the stable operation of the extruder body and solves the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an extrusion unit for graphene conductive materials, comprising an extruder body, and further comprising:

[0007] The feeding mechanism, located at the top of the extruder body, is used to add graphene conductive material into the extruder body.

[0008] The feeding mechanism includes a feeding hopper. Movable baffles are movably inserted into both ends of the bottom inner side of the feeding hopper. A baffle plate is fixedly installed on the outer wall of the opposite end of the two movable baffles. Movable racks are fixedly installed on both sides of the baffles. A rotating shaft is provided at the junction of the two movable baffles. A second motor is provided on one side of the rotating shaft. Rotating gears are fixedly sleeved on both outer walls of the rotating shaft. The rotating gears mesh with the two movable racks on the same side. Wedge plates are fixedly installed at both ends of the inner wall of the feeding hopper. The two wedge plates are respectively located on the top of the two movable baffles.

[0009] Preferably, the extruder body includes a support base, a control box is fixedly installed on one side of the outer wall of the support base, a fixed outer shell is fixedly installed on the top of the support base, and a feed port is opened at one end of the top of the fixed outer shell.

[0010] Preferably, a sealing plate is fixedly installed on the outer wall of one end of the fixed housing, and an extrusion plate is fixedly installed on the other end of the fixed housing by bolts. Both ends of the sealing plate are rotatably inserted with helical rods, and a first motor is fixedly installed on the outer wall of one end of the sealing plate.

[0011] Preferably, a transmission gear is fixedly sleeved on the outer side of the first motor output shaft and one of the screw rods, and the two transmission gears mesh. A synchronous pulley is fixedly sleeved on the outer side of the first motor and the other screw rod, and a synchronous belt is sleeved on the outer side of the two synchronous pulleys.

[0012] Preferably, the top of the fixed outer shell is fixedly connected to the hopper, the bottom cross-sectional area of ​​the inner wall of the hopper is the same as the area of ​​the inlet, and movable grooves are provided on the inner walls at both ends of the hopper.

[0013] Preferably, the inner wall of the movable trough is slidably connected to the outer wall of the adjacent movable baffle, and an installation rod is rotatably installed on the top inner side of the hopper, with a third motor provided on one side of the installation rod.

[0014] Preferably, multiple stirring rods are fixedly sleeved on the outside of the mounting rod, and a flipping plate is fixedly installed on the outside of the multiple stirring rods.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The control box drives the second motor to rotate the rotating shaft. Through the meshing action between the rotating gear and two adjacent movable racks, the two movable baffles can move relative to each other or away from each other along the inner wall of the movable groove. This allows for convenient adjustment of the size of the bottom opening of the feeding hopper, and convenient control of the amount of conductive material entering the extruder body. This avoids a large amount of conductive material entering the extruder body at once, which could affect the operation of the extruder. At the same time, the wedge plate can intercept the raw material on the surface of the movable baffle, preventing the raw material from entering the inner wall of the movable groove and causing wear on the movable groove and movable baffle. This allows the feeding mechanism to stably control the feeding amount of graphene conductive material, thereby ensuring the stable operation of the extruder body.

[0017] 2. The control box enables the third motor to drive the mounting rod to rotate, which in turn allows multiple stirring rods to stir the graphene conductive material inside the hopper. At the same time, the rotation of the stirring rods can drive multiple flipping plates to rotate, which can flip the raw materials on the top of the movable baffle, making the raw materials more thoroughly mixed.

[0027] This utility model provides, for example Figure 1 The graphene conductive material extrusion unit shown includes an extruder body 1, and further includes:

[0028] The feeding mechanism 2, located at the top of the extruder body 1, is used to add graphene conductive material into the extruder body 1.

[0029] To facilitate the control of the amount of graphene conductive material fed, such as Figure 1-3 and Figure 5 As shown, the feeding mechanism 2 includes a feeding hopper 201. Movable baffles 203 are movably inserted into both ends of the bottom inner side of the feeding hopper 201. A baffle plate 204 is fixedly installed on the outer wall of the opposite ends of the two movable baffles 203. Movable racks 205 are fixedly installed on both sides of the baffles 204. A rotating shaft 206 is located at the junction of the two movable baffles 203. A second motor 207 is located on one side of the rotating shaft 206. Rotating gears 208 are fixedly sleeved on both outer walls of the rotating shaft 206. The rotating gears 208 mesh with the two movable racks 205 on the same side. Wedge plates 209 are fixedly installed at both ends of the inner wall of the feeding hopper 201. The two wedge plates 209 are respectively positioned at... The top of the two movable baffles 203 is driven by the second motor 207 to rotate the rotating shaft 206, which in turn causes the two rotating gears 208 to rotate. Through the meshing action between the rotating gears 208 and the two adjacent movable racks 205, the two baffles 204 move relative to or away from each other, which can drive the two movable baffles 203 to move relative to or away from each other. This can adjust the size of the bottom opening of the feed hopper 201 and control the amount of conductive material entering the extruder body 1. At the same time, the wedge plate 209 can clean the top surface of the movable baffles 203, which can prevent residual raw materials from causing wear on the movable baffles 203 and the feed hopper 201.

[0030] To facilitate the extrusion of graphene conductive materials, such as Figure 1-2 and Figure 4As shown, the extruder body 1 includes a support base 101. A control box 102 is fixedly installed on one side of the outer wall of the support base 101. A fixed housing 103 is fixedly installed on the top of the support base 101. A feed inlet 104 is opened at one end of the top of the fixed housing 103. A sealing plate 105 is fixedly installed on the outer wall of one end of the fixed housing 103. An extrusion orifice plate 111 is fixedly installed on the other end of the fixed housing 103 by bolts. A screw rod 106 is rotatably inserted into both ends of the sealing plate 105. A first motor 107 is fixedly installed on the outer wall of one end of the sealing plate 105. A transmission gear 108 is fixedly sleeved on the outer side of the output shaft of the first motor 107 and one of the screw rods 106. The two transmission gears 108 mesh. Synchronous pulleys 109 are fixedly sleeved on the outer sides of both 107 and another screw rod 106. Synchronous belts 110 are sleeved on the outer sides of the two synchronous pulleys 109. Raw materials can be added into the fixed housing 103 through the feed port 104. The control box 102 causes the first motor 107 to drive the adjacent synchronous pulleys 109 and transmission gears 108 to rotate. Through the meshing between the gears and the transmission action of the synchronous belts 110, the other transmission gear 108 and synchronous pulleys 109 rotate accordingly, which in turn drives the two screw rods 106 to rotate relative to each other. This allows the graphene conductive material to be spirally conveyed and plasticized. Then, the conductive material can be extruded through the extrusion plate 111.

[0031] In order to ensure that the raw materials of graphene conductive materials are fully mixed, such as Figure 2 and Figure 4-5 As shown, the top of the fixed outer shell 103 is fixedly connected to the hopper 201. The cross-sectional area of ​​the bottom inner wall of the hopper 201 is the same as that of the inlet 104. Movable grooves 202 are provided on the inner walls of both ends of the hopper 201. The inner wall of the movable groove 202 is slidably connected to the outer wall of the adjacent movable baffle 203. An installation rod 210 is rotatably installed on the top inner side of the hopper 201. A third motor 211 is provided on one side of the installation rod 210. Multiple stirring rods 212 are fixedly sleeved on the outside of the installation rod 210. The outside of the multiple stirring rods 212 is fixed Equipped with a flipping plate 213, the bottom opening of the hopper 201 is connected to the feed inlet 104, allowing the conductive material inside the hopper 201 to enter the fixed housing 103 through the feed inlet 104. At the same time, the control box 102 causes the third motor 211 to drive the mounting rod 210 to rotate, so that multiple stirring rods 212 can stir the raw materials inside the hopper 201. The rotation of the stirring rods 212 can also drive the flipping plate 213 to flip the raw materials on the top of the movable baffle 203, making the mixing of the raw materials more thorough.

[0032] During the extrusion of graphene conductive material, the mixed raw materials are added into the hopper 201. The control box 102 drives the third motor 211 to rotate the mounting rod 210, causing multiple stirring rods 212 to stir and mix the raw materials inside the hopper 201. Simultaneously, the stirring rods 212 drive the tilting plate 213 to tilt the raw materials on top of the movable baffle 203, ensuring thorough mixing of the various raw materials for the conductive material. Then, the control box 102 drives the second motor 207 to rotate the rotating shaft 206, thereby... The rotation of two rotating gears 208 causes the two baffles 204 to move in opposite directions through the meshing of the rotating gears 208 with the two adjacent movable racks 205. This, in turn, causes the two movable baffles 203 to move in opposite directions along the inner walls of the adjacent movable grooves 202. This allows for adjustment of the size of the bottom opening of the hopper 201, thereby controlling the amount of raw material entering the fixed housing 103. At the same time, the wedge plate 209 can clean the raw material on the surface of the movable baffles 203, preventing the raw material from entering the inner wall of the movable grooves 202 and causing wear.

[0033] The raw material inside the hopper 201 enters the fixed housing 103 through the feed inlet 104. The control box 102 drives the first motor 107 to rotate one of the synchronous pulleys 109 and the transmission gear 108. Through the meshing of the gears and the transmission action of the synchronous belt 110, the other transmission gear 108 and the synchronous pulley 109 rotate, which in turn drives the two screw rods 106 to rotate relative to each other inside the fixed housing 103. This allows for the conveying and plasticizing of the conductive material entering the fixed housing 103. The graphene conductive material can be extruded through the extrusion plate 111. The feeding mechanism 2 allows for convenient control of the amount of conductive material fed, preventing the raw material from accumulating in large quantities inside the extruder body 1. This ensures the working condition of the extruder body 1 and improves the extrusion efficiency of the graphene conductive material. This embodiment specifically solves the problem in the prior art where the amount of conductive material fed cannot be conveniently controlled, leading to raw material accumulation that affects the working condition of the extruder.

[0034] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
