Description

Technical Field

[0001] The present application relates to the technical field of extrusion devices, and in particular to a base film material extrusion device and a method of use. Background Art

[0002] In the production process of base film materials, the extrusion device, namely 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 columnar shape to a sheet shape. When the traditional base film extrusion head is initially injected with material, it is easy for the material to fail to fill the interior due to poor fluidity of the material, thereby causing a portion of the base film to be missing during extrusion, reducing the base film extrusion quality. At the same time, when the traditional basic die head is adding additional materials, multiple materials are generally superimposed and injected into the extrusion cavity of the extrusion head. Before entering the extrusion cavity, the base film materials will be misaligned due to inconsistent flow rates of the materials, resulting in uneven distribution when entering the extrusion cavity, which not only reduces the extrusion quality of the base film, but also easily clogs the extrusion head.

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0037] like Figures 1-6 As shown, a base film material extrusion device proposed in one embodiment of the present application includes:

[0038] The die head 1 is set in a lower cone 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 constructed between the upper module 101 and the lower module 102. The small end of the fan-shaped extrusion cavity 103 is connected to the confluence cavity 104. The die head 1 is an existing extrusion head structure, which mainly includes an upper module 101 and a lower module 102. A heating rod is also installed thereon to ensure that the material therein is always in a molten state. The fan-shaped extrusion cavity 103 and the confluence cavity 104 are both constructed 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;

[0039] The mounting portion 2 is protruding from the flat end of the die head 1. A rectangular insert 201 is configured inside the mounting portion 2. The mounting portion 2 is configured at the end of the fan-shaped extrusion cavity 103 of the die head 1. The confluence cavity 104 is configured in the mounting portion 2.

[0040] The inlet pipe 3 is inserted and installed in the rectangular insert 201. The inlet pipe 3 includes a rectangular frame 301. One end of the rectangular frame 301 is connected to a conical cover 302. The other end of the conical cover 302 is configured with a docking circular pipe 303. The other end of the rectangular frame 301 is configured with two oppositely arranged side plates 304. The setting of the rectangular insert 201 is mainly used to guide the installation of the inlet pipe 3, ensuring 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 flows evenly when entering the fan-shaped extrusion cavity 103, and avoid the fan-shaped extrusion cavity 103 due to the flow of the material. To prevent the inconsistent amount of material from causing cavities, a guide assembly 4 is installed between the two side plates 304. The guide assembly 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. First, the material is mainly injected into one half of the fan-shaped extrusion cavity 103 through the guide assembly 4, and second, the material is injected into the other half of the fan-shaped extrusion cavity 103 through the guide assembly 4. This operation can ensure that the material is fully filled in the fan-shaped extrusion cavity 103 when the material is first injected, avoiding the occurrence of cavities and ensuring the quality of base film extrusion.

[0041] The filling component 5 includes a filling tube frame 501 slidably inserted in the rectangular frame 301 for injecting base membrane material. The rectangular frame 301 is equipped with an adjusting member 502 for controlling the sliding of the filling tube frame 501. The filling component 5 is configured to add additional material to the base membrane material in the rectangular frame 301 so that the material covers the upper surface of the base membrane material to form a double-layer base membrane. At the same time, the position of the end of the filling tube frame 501 in the rectangular frame 301 can also be adjusted by the adjusting member 502. Because the end of the filling tube frame 501 is located inside the rectangular frame 301, when it penetrates into the rectangular frame 301, it can hinder the flow of the original base membrane material and increase the flow of the added material. On the contrary, when the filling tube frame 501 is withdrawn toward the outside of the rectangular frame 301, the internal flow space of the rectangular frame 301 will be opened, thereby ensuring the flow of the original base membrane material and reducing the flow of the added material, thereby flexibly controlling the shape of the double-layer structure and increasing the functionality of the device.

[0042] The lubricant adding pipeline 6 is provided between the inlet pipe 3 and the inner wall of the filling pipe frame 501. The lubricant mainly comprises: oleamide, which is soluble in ethanol and ether, has good internal and external lubrication, can reduce melt viscosity, improve fluidity, and is suitable for plastic processing;

[0043] When the device as a whole is working, it is first necessary to use the guide component 4 to evenly spread the base film material in the fan-shaped extrusion cavity 103, and then use the adjustment part 502 in the filling component 5 to adjust the position of the filling pipe frame 501 in the rectangular frame 301 to adjust the injection thickness of the additional superimposed material. When performing these two tasks, the lubricant adding pipeline 6 can be used to inject lubricant into the inlet pipe 3 and the filling pipe frame 501, and the lubricant is used to lubricate the edge of the material flowing through to avoid blockage and increase safety.

[0044] like Figure 3 and Figure 8 As shown, the specific internal structure of the mounting portion 2 of the present application is disclosed to ensure the installation sealing of the inlet pipe 3. A stepped groove is formed between the rectangular insert 201 and the inner hole of the mounting portion 2, and the rectangular frame 301 is inserted into the rectangular insert 201. It should be noted that a stepped groove is formed between the rectangular insert 201 and the confluence cavity 104. After the rectangular frame 301 is inserted therein, it will dock with the stepped groove, thereby docking the inner wall with the confluence cavity 104, ensuring the smooth flow of materials, and the rectangular frame 301 and the rectangular insert 2 are connected. 01 is set to a plug-in relationship, which can easily pull out the inlet pipe 3 from it for subsequent maintenance and replacement, increasing convenience. The side plate 304 is inserted in the confluence chamber 104 and the end is in contact with the intersection of the fan-shaped extrusion chamber 103 and the confluence chamber 104. On the one hand, the side plate 304 is used to install the guide component 4 to facilitate the guide component 4 to guide the direction of the material entering the fan-shaped extrusion chamber 103. On the other hand, it can increase the contact area with the confluence chamber 104, prevent material leakage, and increase safety.

[0045] like Figure 6-Figure 8 As shown, the specific structure of the diversion component 4 of the present application is disclosed, which diverts the material in two directions in sequence to ensure the filling effect. The diversion component 4 includes two U-shaped pieces 401, and an elastic piece 402 is constructed at one end of the U-shaped piece 401. The elastic piece 402 is 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 constructed with an arc corner 404. The mounting portion 2 is constructed with an arc-shaped active cavity 202 located on both sides of the confluence cavity 104. The two U-shaped pieces 401 are slidably mounted in the arc-shaped active cavity 202 and flip and slide in the arc-shaped active cavity 202 around the connection point. Drive members for driving the two U-shaped pieces 401 to flip are provided on both sides of the mounting portion 2. 403. 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 an elastic piece 402, and with this point as the flipping point, the driving member 403 can push one of the U-shaped pieces 401 to move between the two side plates 304, from being parallel to the side plates 304 to being inclined to the side plates 304, so as to guide the material to one side of the fan-shaped extrusion cavity 103, and vice versa, to the other side of the fan-shaped extrusion cavity 103. The two cycle switching can spread the material more evenly into the fan-shaped extrusion cavity 103, avoid the generation of cavity phenomenon, increase safety, and ensure the extrusion quality of the base film.

[0046] like Figure 7-Figure 8 As shown, the specific structure of the driving member 403 of the present application is disclosed to ensure the separate movement of the U-shaped piece 401. The driving member 403 includes a cylinder frame 4031 fixedly connected to both sides of the mounting portion 2, one end of the cylinder frame 4031 is inserted into the arc-shaped active cavity 202, and a piston block 4032 is slidably installed in the cylinder frame 4031. The piston block 4032 is fixedly connected to a push rod 4033 that passes through the other end of the cylinder frame 4031. A baffle 4011 is installed through one end of the U-shaped piece 401 located in the arc-shaped active cavity 202, and the end of the cylinder frame 4031 located in the arc-shaped active cavity 202 is arranged opposite to the baffle 4011. The two driving forces can respectively drive the two push rods 4033 to move, thereby controlling the piston block 4032 to push the baffle 4011 to move, so that the U-shaped piece 401 is flipped around the connection point to achieve the material diversion effect.

[0047] like Figure 7As shown, a driving member 403 in another embodiment of the present application is disclosed, which realizes the synchronous and reverse pushing of the piston blocks 4032 by a single driving force to move. A ventilation pipe 4034 is connected between the two cylinder frames 4031, and the two ends of the ventilation pipe 4034 are respectively connected between the piston block 4032 and one end of the cylinder frame 4031 located on the outside. 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 in the two cylinder frames 4031, the pressure chambers in the two cylinder frames 4031 can be connected. When one of the piston blocks 4032 moves toward 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. At the same time, it can be achieved by relying on only one electric push rod 4035. The staggered movement of the two U-shaped pieces 401 can be realized by a single driving force, thereby increasing the linkage of the device.

[0048] like Figure 4 As shown, the specific structure of the filling pipe frame 501 of the present application is disclosed, which prevents the material from entering the filling pipe frame 501 due to pressure and causing blockage. The upper end of the rectangular frame 301 is constructed with a connecting pipe 3011 arranged obliquely downward toward the confluence chamber 104, and the filling pipe frame 501 is slidably installed in the connecting pipe 3011. A baffle 5011 is constructed on one side of the opening at the bottom end of the filling pipe frame 501. The baffle 5011 is arranged on the side away from the side plate 304, and an angled material port 5012 is constructed between the baffle 5011 and the other side of the opening. The baffle 5011 is arranged at the bottom end of the filling pipe frame 501 to block the original base membrane material flowing through, and prevent the material from flowing back into the filling pipe frame 501 due to pressure, thereby increasing safety. The angled material port 5012 can ensure that the additional material can be smoothly injected from the filling pipe frame 501 into the rectangular frame 301, thereby ensuring the smooth operation of the device.

[0049] like Figure 4 As shown, the specific structure of the adjustment member 502 of the present application is disclosed to ensure the smooth operation of the device. The adjustment member 502 includes a U-shaped frame 5021 constructed on the upper side of the rectangular frame 301, and 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. The driving motor 5025 can drive the rotating shaft 5022 to rotate, thereby driving the meshing rack 5024 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 original base membrane material, and increasing the flexibility of the device.

[0050] like Figure 4、 Figure 6 and Figure 8 As shown, the specific structure of the lubricant adding pipeline 6 of the present application is disclosed, so that the lubricant is dispersed in the filling pipe frame 501 and the side plate 304 to ensure the lubricating effect of the lubricant. The lubricant adding pipeline 6 includes a flow hole 601 constructed in the two side walls of the rectangular frame 301, and the two side plates 304 are constructed with a liquid outlet pipeline 602 connected to the flow hole 601. The opposite sides of the two side plates 304 are constructed with a plurality of injection holes 603 connected to the liquid outlet pipeline 602. The U-shaped piece 401 covers the injection hole 603. When the guide component 4 is working, the lubricant needs to be injected synchronously to avoid material clogging. The U-shaped piece 401 is set in a position covering the injection hole 603. On the one hand, it can ensure that the raw material does not clog the injection hole 603 under normal conditions. On the other hand, the lubricant can be gradually injected during the reciprocating flipping of the U-shaped piece 401. The filling pipe frame 501 is arranged on both sides of the material flow so as to separate the material from the inner wall of the device by the lubricant, ensure the lubrication effect and avoid blockage. The inner array structure of the side wall of the filling pipe frame 501 is provided with a plurality of row-type pipes 604 that are interconnected. The top of the filling pipe frame 501 is provided with a plurality of filling holes 605 that are connected to the row-type pipes 604. A flexible pipe 606 is connected between the flow hole 601 and the row-type pipe 604. The mounting portion 2 is provided with a liquid storage and injection portion 7 that is connected to the flexible pipe 606. By arranging the filling hole 605 at the inner top of the filling pipe frame 501, 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, so as to use the lubricant to separate the material, ensure the lubrication effect, avoid material blockage and increase safety.

[0051] like Figure 6-Figure 8 As shown, the specific structure of the liquid storage and injection part 7 of the present application is disclosed to ensure the smooth injection of lubricant. The liquid storage and injection part 7 includes a groove 701 constructed on the mounting part 2, and a horizontally arranged liquid storage bottle 702 is inserted in the groove 701. The liquid storage bottle 702 is provided with an outlet pipe 703 at one end of which is located on the inner bottom side thereof, and the other end of the outlet pipe 703 is connected to the flexible tube 606. An air pump 704 is fixedly inserted in the liquid storage bottle 702, and the movable end of the air pump 704 is fixedly connected to a connecting plate 705, and the other end of the connecting plate 705 is connected to the movable end of the electric push rod 4035. When the guide component 4 is in operation, the electric push rod 4035 needs to be telescopically moved, and this movement can simultaneously drive the connecting plate 705 to move back and forth, so as to squeeze the air pump 704 to inflate the liquid storage bottle 702, and use the air pressure to squeeze the lubricant therein and inject it into the flexible tube 606, so as to achieve the synchronous addition effect of the lubricant and increase the synchronization of the device operation.

[0052] like 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:

[0053] S1, material injection, connect the injection molding extruder through the docking circular tube 303, and inject the molten material into the inlet pipe 3. At this time, the electric push rod 4035 is started to drive the push rod 4033 to extend and retract. The piston block 4032 and the vent pipe 4034 are linked to adjust the air pressure in the cylinder frame 4031 on both sides, driving the baffle 4011 to slide in the arc-shaped active cavity 202, so that one of the U-shaped pieces 401 flips 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 extension and retraction of the electric push rod 4035 drives the other U-shaped piece 401 to flip, and the material quickly fills the other half of the space of the fan-shaped extrusion cavity 103;

[0054] S2. Additional material is injected from the filling pipe frame 501. 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. 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.

[0055] 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. The lubricant is then diverted through the outlet pipe 703 and the flexible tube 606 to the discharge pipe 604 and the flow hole 601. The lubricant is then injected into the surface of the guide component 4 and the base membrane material through the injection hole 603 and the filling hole 605.

[0056] S4, the base film material enters from the docking circular tube 303, flows evenly through the guide component 4, and then flows into the fan-shaped extrusion cavity 103 through the confluence cavity 104, and is finally extruded from the small end to form.

[0057] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one 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. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
