Description

Technical Field

[0002] In the production process of base film materials, the extrusion device, i.e., the base film extrusion head, is one of the key devices. It is responsible for the basic shaping of the material, transforming the material melted by the extruder from a cylindrical shape into a sheet shape. In the traditional base film extrusion head, when the material is initially injected, it is very easy for the material to not fill its interior due to poor fluidity of the material, and then a part of the base film is missing during extrusion, reducing the quality of the base film extrusion. At the same time, when the traditional base die head adds additional materials, generally, multiple materials are superposed and injected into the extrusion cavity in the extrusion head. Before entering the extrusion cavity, the multiple materials will be misaligned due to inconsistent flow velocities of the materials, resulting in uneven distribution when entering the extrusion cavity, not only reducing the extrusion quality of the base film, but also easily clogging the inside of the extrusion head.

Detailed implementation manners

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application.

[0018] As Figures 1-6 shown, a base film material extrusion device proposed in an embodiment of this application includes: The die head 1 is arranged in a downward conical shape. The die head 1 includes an upper module 101 and a lower module 102 fixed by bolts. A fan-shaped extrusion cavity 103 is formed between the upper module 101 and the lower module 102. The small-mouth end of the fan-shaped extrusion cavity 103 is communicated with a confluence cavity 104. The die head 1 is an existing extrusion head structure, which mainly includes the upper module 101 and the lower module 102. A heating rod is also installed thereon to ensure that the material inside is always in a molten state. The fan-shaped extrusion cavity 103 and the confluence cavity 104 are both formed between the upper module 101 and the lower module 102. When the material flows in, it will gradually diffuse into the fan-shaped extrusion cavity 103 through the confluence cavity 104 and finally be extruded from the small-head end of the die head 1; The installation part 2 protrudes from the flat end of the die head 1. A rectangular insertion tube 201 is formed inside the installation part 2. The installation part 2 is formed at the port of the fan-shaped extrusion cavity 103 of the die head 1, and the confluence cavity 104 is formed inside the installation part 2; The inlet pipe 3 is inserted and installed in the rectangular insertion tube 201. The inlet pipe 3 includes a rectangular frame 301. One end of the rectangular frame 301 is communicated with a conical cover 302. The other end of the conical cover 302 is formed with a docking round tube 303. The other end of the rectangular frame 301 is formed with two oppositely arranged side plates 304. The setting of the rectangular insertion tube 201 is mainly used to guide the installation of the inlet pipe 3 to ensure that the two side plates 304 can be accurately and parallelly inserted at the port of the fan-shaped extrusion cavity 103, so as to ensure that the material flow is uniform when the material enters the fan-shaped extrusion cavity 103, avoid the occurrence of cavity phenomenon due to inconsistent material flow in the fan-shaped extrusion cavity 103, and increase safety. A flow guiding component 4 is installed between the two side plates 304. The setting of the flow guiding component 4 can divide the action of directly injecting the material from the rectangular frame 301 into the fan-shaped extrusion cavity 103 into two parts. One is to mainly inject the material into half of the fan-shaped extrusion cavity 103 through the flow guiding component 4, and the other is to inject the material into the other half of the fan-shaped extrusion cavity 103 through the flow guiding component 4. Such an operation can make the material fill the fan-shaped extrusion cavity 103 completely when the material is just injected, avoid the occurrence of cavity phenomenon, and ensure the quality of the base film extrusion; The filling component 5 includes a filling pipe frame 501 slidably inserted into a rectangular frame 301 for injecting base film material. An adjusting member 502 for controlling the sliding of the filling pipe frame 501 is installed on the rectangular frame 301. The filling component 5 is provided to additionally add material to the base film material within the rectangular frame 301, so that the material covers the upper surface of the base film material to form a double-layer structure base film. At the same time, the position of the end of the filling pipe frame 501 within the rectangular frame 301 can also be adjusted through the adjusting member 502. Since the end of the filling pipe frame 501 is located inside the rectangular frame 301, when it penetrates into the rectangular frame 301, it can obstruct the flow rate of the original base film material and increase the flow rate of the added material. On the contrary, when the filling pipe frame 501 is pulled out towards the outside of the rectangular frame 301, the internal flow space of the rectangular frame 301 will be opened, ensuring the flow rate of the original base film material and reducing the flow rate of the added material, so as to flexibly control the form of the double-layer structure and increase the functionality of the device; The lubricant addition pipeline 6 is arranged between the inflow pipe 3 and the inner wall of the filling pipe frame 501. The lubricant mainly includes: oleic acid amide, which is soluble in ethanol and ether, has good internal and external lubrication effects, can reduce the melt viscosity, improve fluidity, and is suitable for plastic processing; When the whole device is working, first, it is necessary to use the diversion component 4 to evenly spread the base film material over the fan-shaped extrusion cavity 103, and then use the adjusting member 502 in the filling component 5 to adjust the position of the filling pipe frame 501 within the rectangular frame 301, so as to adjust the injection thickness of the additionally stacked material. When performing these two operations, the lubricant addition pipeline 6 can be used to inject lubricant into the inflow pipe 3 and the filling pipe frame 501, and use the lubricant to lubricate the edges where the material flows through, avoid blockage, and increase safety.

[0019] As Figure 3 and Figure 8 shown, the specific internal structure of the installation part 2 of the present application is disclosed to ensure the installation sealing performance of the inflow pipe 3. A stepped groove is formed between the rectangular insertion tube 201 and the inner hole of the installation part 2. The rectangular frame 301 is inserted into the rectangular insertion tube 201. It should be noted that a stepped groove is formed between the rectangular insertion tube 201 and the confluence cavity 104. After the rectangular frame 301 is inserted therein, it will be docked with the stepped groove, so that the inner wall is docked with the confluence cavity 104 to ensure the smooth flow of the material. And the rectangular frame 301 and the rectangular insertion tube 201 are set in a plug-in relationship, which can facilitate the extraction of the inflow pipe 3 therefrom for subsequent maintenance and replacement, increasing convenience. The side plate 304 is inserted into the confluence cavity 104 and the end abuts against the junction of the fan-shaped extrusion cavity 103 and the confluence cavity 104. On the one hand, the side plate 304 is used to install the diversion component 4 to facilitate the diversion of the material entering the fan-shaped extrusion cavity 103 by the diversion component 4. On the other hand, it can increase the contact area with the confluence cavity 104 to prevent material leakage and increase safety.

[0020] AsFigures 6-8 As shown in the figure, the specific structure of the diversion component 4 of the present application is disclosed, which conducts two-way sequential diversion of materials to ensure the filling effect. The diversion component 4 includes two U-shaped pieces 401. One end of the U-shaped piece 401 is configured with an elastic piece 402 made of spring steel. The elastic piece 402 is connected to the opposite surfaces of the two side plates 304. The other end of the U-shaped piece 401 is configured with an arc angle 404. An arc-shaped movable cavity 202 located on both sides of the confluence cavity 104 is configured in the installation part 2. The two U-shaped pieces 401 are slidably installed in the arc-shaped movable cavity 202 and flip and slide in the arc-shaped movable cavity 202 around the connection point. Driving members 403 for driving the two U-shaped pieces 401 to flip are arranged on both sides of the installation part 2. It should be noted that the open end of the U-shaped piece 401 is inserted into the arc-shaped movable cavity 202, and one side end thereof is connected to the side plate 304 through the elastic piece 402, and this point is used as the flipping point. The driving member 403 can push one of the U-shaped pieces 401 to move towards the space between the two side plates 304, changing from being parallel to the side plate 304 to being inclined to the side plate 304, so as to divert the material to one side of the fan-shaped extrusion cavity 103, and vice versa to divert it to the other side of the fan-shaped extrusion cavity 103. By switching between these two cycles, the material can be more evenly spread into the fan-shaped extrusion cavity 103, avoiding the generation of cavity phenomena, increasing safety, and ensuring the extrusion quality of the base film.

[0021] As Figures 7-8 As shown in the figure, the specific structure of the driving member 403 of the present application is disclosed to ensure the separate movement of the U-shaped pieces 401. The driving member 403 includes air cylinder frames 4031 fixedly connected to both sides of the installation part 2. One end of the air cylinder frame 4031 is inserted into the arc-shaped movable cavity 202. A piston block 4032 is slidably installed in the air cylinder frame 4031. A push rod 4033 passing through the other end of the air cylinder frame 4031 is fixedly connected to the piston block 4032. A retaining piece 4011 is inserted through one end of the U-shaped piece 401 located in the arc-shaped movable cavity 202. One end of the air cylinder frame 4031 located in the arc-shaped movable cavity 202 is arranged opposite to the retaining piece 4011. By two driving forces, the two push rods 4033 can be respectively driven to move, thereby controlling the piston block 4032 to push the retaining piece 4011 to move, so that the U-shaped piece 401 flips around the connection point, realizing the diversion effect of the material.

[0022] As Figure 7 ​As shown in the figure, the driving member 403 in another embodiment of the present application is disclosed, which realizes the single driving force to synchronously and reversely push the piston block 4032 to move. A ventilation pipe 4034 is connected between the two cylinder frames 4031. The two ends of the ventilation pipe 4034 are respectively connected between the piston block 4032 and the outer end of the cylinder frame 4031. An electric push rod 4035 connected to one of the push rods 4033 is fixedly connected to the die head 1. By connecting the ventilation pipe 4034 between the two cylinder frames 4031, the pressure chambers in the two cylinder frames 4031 can be connected. When one piston block 4032 moves towards the baffle 4011, the other piston block 4032 will move away from the baffle 4011, and vice versa. In this way, the staggered movement of the two push rods 4033 can be realized, and it can be achieved only by relying on one electric push rod 4035. The single driving force realizes the staggered movement of the two U-shaped pieces 401, increasing the linkage of the device.

[0023] As Figure 4 As shown in the figure, the specific structure of the filling pipe frame 501 of the present application is disclosed to prevent materials from entering the filling pipe frame 501 due to pressure and causing blockage. The upper end of the rectangular frame 301 is provided with a connecting pipe 3011 inclined downward towards the confluence chamber 104. The filling pipe frame 501 is slidably installed in the connecting pipe 3011. A flow blocking plate 5011 is constructed on one side inside the bottom opening of the filling pipe frame 501. The flow blocking plate 5011 is arranged on the side away from the side plate 304. An inclined material port 5012 is constructed between the flow blocking plate 5011 and the other side inside the opening. By setting the flow blocking plate 5011 at the bottom end of the filling pipe frame 501, the flowing raw base film material can be blocked, preventing the material from flowing back into the filling pipe frame 501 due to pressure and increasing safety. And setting the inclined material port 5012 can ensure that the additionally added material can be smoothly injected from the filling pipe frame 501 into the rectangular frame 301, ensuring the smooth operation of the device.

[0024] As Figure 4 As shown in the figure, the specific structure of the adjusting member 502 of the present application is disclosed to ensure the smooth operation of the device. The adjusting member 502 includes a U-shaped frame 5021 constructed on the upper side of the rectangular frame 301. A rotating shaft 5022 is rotatably installed on the U-shaped frame 5021. A driving gear 5023 is sleeved on the rotating shaft 5022. A rack 5024 meshing with the driving gear 5023 is constructed on the side of the filling pipe frame 501 opposite to the U-shaped frame 5021. A driving motor 5025 connected to the rotating shaft 5022 is fixedly connected to one side of the U-shaped frame 5021. By driving the driving motor 5025, the rotating shaft 5022 can be driven to rotate, and then the engaged rack 5024 can be driven to move through the driving gear 5023, thereby adjusting the position of the filling pipe frame 501 in the connecting pipe 3011, realizing its telescopic movement, flexibly changing the flow rate of the raw base film material, and increasing the flexibility of the device.

[0025] As Figure 4, Figure 6 and Figure 8 As shown in Figure 6 and Figure 8 , the specific structure of the lubricant addition pipeline 6 of the present application is disclosed, enabling the lubricant to be dispersed within the filling pipe frame 501 and the side plates 304, ensuring the lubrication effect of the lubricant. The lubricant addition pipeline 6 includes flow holes 601 constructed within the two side walls of the rectangular frame 301. Liquid outlet pipelines 602 connected to the flow holes 601 are constructed within the two side plates 304. A plurality of injection holes 603 connected to the liquid outlet pipelines 602 are constructed on the opposite sides of the two side plates 304. The U-shaped piece 401 covers the injection holes 603. When the diversion assembly 4 operates, the lubricant needs to be injected synchronously to avoid material blockage. By setting the U-shaped piece 401 at the position covering the injection holes 603, on the one hand, it can ensure that the raw materials do not block the injection holes 603 under normal conditions, and on the other hand, it can gradually squeeze the lubricant into both sides of the material flow during the reciprocating flipping of the U-shaped piece 401, so as to separate the material from the inner wall of the device using the lubricant, ensuring the lubrication effect and avoiding blockage. A plurality of mutually connected row-shaped pipelines 604 are arrayed and constructed within the upper side wall of the filling pipe frame 501. A plurality of filling holes 605 connected to the row-shaped pipelines 604 are constructed at the top inside the filling pipe frame 501. A flexible pipe 606 is connected between the flow holes 601 and the row-shaped pipelines 604. A liquid storage injection part 7 connected to the flexible pipe 606 is provided on the installation part 2. By setting the filling holes 605 at the top inside the filling pipe frame 501, the lubricant can be added to the upper surface of the additional material. When the additional material enters the rectangular frame 301, the lubricant will adhere to the inner top surface of the rectangular frame 301, thereby using the lubricant to separate the material, ensuring the lubrication effect, avoiding material blockage, and increasing safety.

[0026] As Figures 6-8 As shown in Figures 6-8 , the specific structure of the liquid storage injection part 7 of the present application is disclosed, ensuring the smooth injection of the lubricant. The liquid storage injection part 7 includes a groove 701 constructed on the installation part 2. A horizontally arranged liquid storage bottle 702 is inserted into the groove 701. An outflow pipe 703 with one end located at its inner bottom side is inserted into the liquid storage bottle 702. The other end of the outflow pipe 703 is connected to the flexible pipe 606. A syringe 704 is fixedly inserted into the liquid storage bottle 702. The movable end of the syringe 704 is fixedly connected to a connecting plate 705. The other end of the connecting plate 705 is connected to the movable end of the electric push rod 4035. When the diversion assembly 4 operates, the electric push rod 4035 needs to move telescopically, and this movement can simultaneously drive the connecting plate 705 to reciprocate, thereby squeezing the syringe 704 to pump air into the liquid storage bottle 702, using air pressure to squeeze the lubricant therein into the flexible pipe 606, thereby achieving the synchronous addition effect of the lubricant and increasing the synchronism of the device operation.

[0027] As Figures 1-8As shown, a method for using a base film material extrusion device, using the above-mentioned base film material extrusion device, specifically includes the following steps: S1, material injection, connecting the circular tube 303 with the injection molding extruder, injecting the molten material into the inlet pipe 3, at this time, starting the electric push rod 4035 to drive the push rod 4033 to extend and retract, and adjusting the air pressure in the cylinder frame 4031 on both sides through the linkage of the piston block 4032 and the vent pipe 4034, driving the baffle 4011 to slide in the arc-shaped active cavity 202, so that one of the U-shaped pieces 401 is turned around the connection point, thereby guiding the flow direction of the material. After the material quickly fills half of the space of the fan-shaped extrusion cavity 103, the other U-shaped piece 401 is turned by the extension and retraction of the electric push rod 4035, so that the material quickly fills the other half of the space of the fan-shaped extrusion cavity 103; S2, additional material is injected from the filling pipe frame 501, and the driving motor 5025 drives the driving gear 5023 to rotate, and the driving rack 5024 drives the filling pipe frame 501 to slide along the connecting pipe 3011, and the flow distribution of the additional material on the base material in the inlet pipe 3 is adjusted by the displacement of the beveled material port 5012; S3, the lubricant is stored in the liquid storage bottle 702. When the electric push rod 4035 is running, it synchronously drives the connecting plate 705 to drive the air pump 704 to pressurize the liquid storage bottle 702, so that the lubricant is sequentially diverted to the discharge pipe 604 and the flow hole 601 through the outlet pipe 703 and the flexible pipe 606, and is respectively injected into the surface of the guide component 4 and the base film material through the injection hole 603 and the filling hole 605; S4, the base film material enters from the docking circular tube 303, flows evenly through the flow guide component 4, and then flows into the fan-shaped extrusion cavity 103 through the confluence cavity 104, and finally is extruded from the small end to be formed.

[0028] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
