Description

Technical Field

[0001] This invention relates to the field of extruder technology, specifically to a waste textile composite material extruder. Background Technology

[0002] Tens of millions of tons of waste textiles are generated globally each year, but traditional treatment methods have fatal shortcomings. About 70% of waste textiles are directly landfilled or incinerated: chemical fiber waste textiles are difficult to degrade after being landfilled and may release microplastics, while incineration produces toxic gases such as dioxins, polluting the air; only 30% are simply recycled: mostly limited to "sorting and refurbishing" or "crushing and making low-end products", the fiber resources are not fully utilized and the added value is extremely low. Therefore, a special equipment is needed to process them. Traditional hydraulic extruders mostly employ a core forming mechanism of "plunger reciprocating push"—using hydraulic power to drive a plunger to reciprocate periodically within a sealed barrel, forcing the material through the die cavity to obtain a preset shape. This method is often ineffective for processing high-strength, highly filled, and long-fiber waste textile composite materials. Furthermore, during the storage and pretreatment stages of waste textile composite materials, air is easily trapped between fibers or within the material. Due to the lack of effective venting channels in the sealed pushing structure of traditional extruders, this air cannot be expelled in time. Consequently, when the material is extruded into the die, the gas in the melt causes depressions or bubbles to form on the surface of the product. This makes the product prone to fracture due to stress concentration during subsequent processing. At the same time, internal voids or bubbles are equivalent to "structural weak points," significantly reducing the tensile strength, flexural strength, and impact strength of the product. Therefore, we designed a waste textile composite material extruder to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a waste textile composite material extruder to address the problem that air can easily be trapped in the gaps or inside of fibers, causing the gas in the melt to form depressions or bubbles on the surface of the product during extrusion, which can lead to stress concentration and breakage during subsequent processing. In addition, internal voids or bubbles can significantly reduce the tensile strength, flexural strength and impact strength of the product.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a waste textile composite material extruder, comprising: a mounting platform, an extrusion frame fixedly connected to the top of the mounting platform, a feeding frame fixedly connected to the top of the extrusion frame, and an extrusion die mounted on one side of the extrusion frame; a multi-stage extrusion mechanism, the multi-stage extrusion device being disposed inside the feeding frame for progressively extruding the raw material, the multi-stage extrusion device comprising two sets of guide blocks fixedly connected to the inside of the feeding frame, the first set having one guide block and the second set having two guide blocks, each guide block having a first inclined surface on both sides, each guide block having two first fixing plates fixedly connected to its bottom, and each first fixing plate having a second fixing plate at its bottom; and an extrusion molding mechanism, the extrusion molding mechanism being disposed inside the extrusion frame for extruding the raw material into shape.

[0005] As a further embodiment of the present invention: the multi-stage extrusion mechanism further includes six sets of first connecting bars fixedly connected to the inner side of the feed frame, and each set of first connecting bars is disposed on one side of a first inclined surface. Each set of first connecting bars has two bars, and one end of each set of two first connecting bars is fixedly connected to a first connecting plate. A second hydraulic cylinder is installed on the top of the first connecting plate, and the output end of the second hydraulic cylinder extends through to the bottom of the first connecting plate and is fixedly connected to the second connecting plate. An extrusion plate is fixedly connected to the bottom of the second connecting plate, and an opening component is disposed on the inner side of the first fixed plate.

[0006] As a further embodiment of the present invention: the top of the first fixing plate is provided with a second inclined surface, and the inner side of the first fixing plate is provided with three rows of conical holes, the three rows of conical holes are staggered, and the diameter of the second group of conical holes is larger than the diameter of the first group of conical holes. The inner side of the second fixing plate is provided with a through hole with the same diameter as the bottom of the conical holes, and the conical holes and the through holes are staggered. The bottom of the extrusion plate is fixedly connected with three sets of extrusion columns with the same diameter as the through holes, and the length of the three sets of extrusion columns decreases sequentially and is arranged in a stepped manner.

[0007] As a further embodiment of the present invention: the opening component includes a limiting groove formed on the inner side of the first fixed plate, a sliding block is slidably connected to the inner side of the limiting groove, and the bottom of the sliding block is fixedly connected to the second fixed plate. A compression spring is installed between the sliding block and the inner side of the limiting groove.

[0008] As a further embodiment of the present invention: the opening component further includes a second connecting strip fixedly connected to the bottom of the second connecting plate, a driving block fixedly connected to the bottom of the second connecting strip, and a third inclined surface provided at the bottom of the driving block; a fixing strip fixedly connected to one end of the first fixing plate; a rotating wheel rotatably connected to the inner side of the fixing strip; and a switching unit provided at the top of the guide block.

[0009] As a further embodiment of the present invention: the switching unit includes multiple drive motors installed on the outside of the feed frame, and the output end of each drive motor is fixedly connected to a rotating rod through the inside of the feed frame. A rotating plate is fixedly connected to the outer wall of the rotating rod. The bottom of the second fixed plate has two third fixed plates, and the two ends of the third fixed plates are fixedly connected to the inside of the feed frame.

[0010] As a further embodiment of the present invention: the extrusion molding mechanism includes a first hydraulic cylinder installed at one end of the extrusion frame, the output end of the first hydraulic cylinder extending through to the inner side of the extrusion frame and fixedly connected to an extrusion block, and a heating unit being provided on the inner side of the feed frame.

[0011] As a further embodiment of the present invention: the heating unit includes a first heating pipe and two second heating pipes installed at the air inlet of the feed frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a multi-stage extrusion mechanism, the extrusion column is driven to move downward and insert into the conical hole. When the bottom of the extrusion column contacts the raw material, the extrusion column continues to move, thereby extruding the raw material. The "wide at the top and narrow at the bottom" structure of the conical hole causes the raw material to naturally gather towards the center when filling. After the extrusion column is accurately inserted, the pressure is evenly transmitted from the top to the bottom, and the air is gradually "squeezed out". At the same time, because the preheated raw material forms an adhesive state, the preheated raw material is in an "adhesive state" (not completely melted, with a certain plasticity but low fluidity). At this time, the gaps between the raw material particles are filled by the softened base material, forming a "semi-dense" agglomerated structure. During extrusion, the air is difficult to escape from the gaps between the raw material particles. Instead, it is forced to the bottom of the conical hole by the pressure of the extrusion column, thereby further improving the degassing effect. The raw material is in a "low gas content and high density" state before entering the final extrusion. There is no excess air escaping during subsequent melt extrusion, thereby improving the appearance quality of the extruded product, reducing surface defects, and thus improving the overall practicality of the device. 2. By setting the opening component, the second fixed plate is moved. When the rotating wheel moves to the top of the third inclined plane, the rotating wheel moves to its maximum position, and the bottom of the through hole coincides with the bottom of the conical hole, thereby opening the channel at the bottom of the first fixed plate. At this time, the extrusion column continues to move downward, thereby pushing the raw material downward and extruding the raw material. This achieves a seamless connection between "degassing and feeding", and simultaneously realizes "channel switching" and "power pushing", simplifying the structure and improving automation efficiency, thereby improving the overall practicality of the device. 3. By setting up a second fixed plate and other parts, the second group of extrusion and extrusion are carried out. Since the diameter of the conical hole in the second group is larger than that in the first group, the raw material can be extruded in stages to achieve "step-by-step compaction + deep degassing", which greatly reduces the air residue rate of the raw material and improves the overall practicality of the device. 4. By setting a switching unit, the rotating plate is driven to rotate, thereby closing the right channel and opening the left channel. This allows the right side to be extruded without any raw material falling, while the other side can be fed. This achieves continuous feeding operation and eliminates the "time overlap conflict" between feeding and extrusion, realizing "zero waiting" continuous production. This improves the extrusion efficiency of the device and enhances its overall practicality. Attached Figure Description

[0017] Please see Figures 1 to 11This embodiment provides a waste textile composite material extruder, including: a mounting platform 1, an extrusion frame 2 fixedly connected to the top of the mounting platform 1, a feed frame 5 fixedly connected to the top of the extrusion frame 2, and an extrusion die 3 installed on one side of the extrusion frame 2; a multi-stage extrusion mechanism, the multi-stage extrusion device being disposed inside the feed frame 5 for progressively extruding the raw material, the multi-stage extrusion device including two sets of guide blocks 8 fixedly connected to the inside of the feed frame 5, the first set of guide blocks 8 having one block, the second set of guide blocks 8 having two blocks, each guide block 8 having a first inclined surface on both sides, and each guide block 8 having two first fixing plates 18 fixedly connected to its bottom. Each first fixed plate 18 has a second fixed plate 19 at its bottom; the multi-stage extrusion mechanism also includes six sets of first connecting bars 12 fixedly connected to the inside of the feed frame 5, and each set of first connecting bars 12 is set on one side of a first inclined surface. Each set of first connecting bars 12 has two bars, and one end of each set of two first connecting bars 12 is fixedly connected to a first connecting plate 13. A second hydraulic cylinder 14 is installed on the top of the first connecting plate 13, and the output end of the second hydraulic cylinder 14 extends through to the bottom of the first connecting plate 13 and is fixedly connected to a second connecting plate 15. An extrusion plate 16 is fixedly connected to the bottom of the second connecting plate 15. An opening component is provided on the inner side of the fixing plate 18; a second inclined surface is provided on the top of the first fixing plate 18, and three rows of conical holes 25 are provided on the inner side of the first fixing plate 18. The three rows of conical holes 25 are staggered, and the diameter of the second set of conical holes 25 is larger than that of the first set of conical holes 25. A through hole 26 with the same diameter as the bottom hole of the conical hole 25 is provided on the inner side of the second fixing plate 19, and the conical holes 25 and the through hole 26 are staggered. The bottom of the extrusion plate 16 is fixedly connected to three sets of extrusion columns 28 with the same diameter as the through hole 26, and the length of the three sets of extrusion columns 28 decreases sequentially and is arranged in a stepped manner; the opening component includes an opening... A limiting groove 22 is provided inside the first fixed plate 18. A sliding block 23 is slidably connected to the inner side of the limiting groove 22, and the bottom of the sliding block 23 is fixedly connected to the second fixed plate 19. A compression spring 24 is installed between the sliding block 23 and the inner side of the limiting groove 22. The opening assembly also includes a second connecting strip 17 fixedly connected to the bottom of the second connecting plate 15. A driving block 27 is fixedly connected to the bottom of the second connecting strip 17, and a third inclined surface is provided at the bottom of the driving block 27. A fixing strip 20 is fixedly connected to one end of the first fixed plate 18. A rotating wheel 21 is rotatably connected to the inner side of the fixing strip 20. A switching unit is provided on the top of the guide block 8. The extrusion molding mechanism is located inside the extrusion frame 2 and is used to extrude raw materials into shape. The extrusion molding mechanism includes a first hydraulic cylinder 4 installed at one end of the extrusion frame 2. The output end of the first hydraulic cylinder 4 passes through the inside of the extrusion frame 2 and is fixedly connected to an extrusion block 7. A heating unit is provided inside the feed frame 5. The heating unit includes a first heating pipe 6 and two second heating pipes 29 installed at the air inlet of the feed frame 5. The first hydraulic cylinder 4 is controlled by a PLC controller, which can control the first hydraulic cylinder 4 to start intermittently. When the extrusion frame 2 is filled, the PLC controller controls the first hydraulic cylinder 4 to start, thereby driving the output end of the first hydraulic cylinder 4 to move to the right, thereby driving the extrusion block 7 to move to the right, thereby performing the final extrusion operation on the raw material, and gradually extruding the raw material into the inner side of the extrusion die 3, thereby finally forming the material. First, the workers connect the first heating pipe 6 and the second heating pipe 29 to the external nitrogen heating pipe. The temperatures of the first heating pipe 6 and the second heating pipe 29 are 80 degrees Celsius and 130 degrees Celsius, respectively. This heats the inlet and the inner side of the feeding frame 5, thus achieving preliminary preheating of the raw material at the inlet and preheating of the inner side. This softens the raw material at the inlet and creates an adhesive state on the inner side of the feeding frame 5 (the waste textile composite material does not melt). At the same time, a heating mechanism is set on the outside of the extrusion frame 2 to finally heat the inner side of the extrusion frame 2. This achieves gradual heating of the raw material, thereby improving the uniformity of heating and thus improving the production quality of the product.

[0018] The second hydraulic cylinder 14 is controlled by a PLC controller, which can control its intermittent operation. After the operator connects the first heating pipe 6 and the second heating pipe 29 to the external nitrogen heating pipe, the operator places the raw material into the feed inlet of the feed frame 5. As the raw material slides down to the top of the first fixed plate 18 under gravity, it continues to move along the second inclined plane. When the raw material reaches the top of the conical hole 25, it continues to move, falling into the inner side of the conical hole 25 and gradually filling it. The PLC controller then controls the second hydraulic cylinder 14 to start, driving the extrusion plate 16 downwards, which in turn moves the extrusion column 28 downwards into the conical hole 25. When the bottom of the extrusion column 28 contacts the raw material, it continues to move, thus... The raw material is extruded, and the "wider at the top and narrower at the bottom" structure of the conical orifice causes the raw material to naturally converge towards the center during filling. After the extrusion column is precisely inserted, the pressure is evenly transmitted from the top to the bottom, and the air is gradually "squeezed out". At the same time, because the preheated raw material forms an adhesive state, it is in an "adhesive state" (not completely melted, with a certain plasticity but low fluidity). At this time, the gaps between the raw material particles are filled by the softened base material, forming a "semi-dense" agglomerated structure. During extrusion, the air is difficult to escape from the gaps between the raw material particles. Instead, it is forced to the bottom of the conical orifice by the pressure of the extrusion column, which further improves the degassing effect. This makes the raw material in a "low gas content and high density" state before entering the final extrusion. There is no excess air escaping during subsequent melt extrusion, thereby improving the appearance quality of the extruded product, reducing surface defects, and improving the overall practicality of the device.

[0019] As the second connecting plate 15 moves downward, it drives the drive block 27 downward. When the bottom of the drive block 27 contacts the rotating wheel 21, the third inclined plane drives the rotating wheel 21 to move towards the sliding block 23, thereby moving the second fixed plate 19. When the rotating wheel 21 moves to the top of the third inclined plane, it reaches its maximum position. At this time, the bottom of the through hole 26 coincides with the bottom of the conical hole 25, thus opening the channel at the bottom of the first fixed plate 18. The extrusion column 28 continues to move downward, pushing the raw material downward and extruding it. This achieves seamless connection between degassing and feeding, simultaneously realizing channel switching and power pushing, simplifying the structure and improving automation efficiency, thereby enhancing the overall practicality of the device. After the first batch of raw materials is extruded, the extruded raw materials fall onto the top of the first fixed plate 18 of the second batch under the action of gravity, and continue to move, thus falling into the inner side of the conical hole 25, thereby gradually filling the conical hole 25, thus carrying out the second batch of compression and extrusion. Since the diameter of the conical hole 25 of the second batch is larger than that of the conical hole 25 of the first batch, the raw materials can be extruded in stages, realizing "step-by-step compaction + deep degassing", which greatly reduces the air residue rate of the raw materials, thereby improving the overall practicality of the device.

[0020] Please see Figures 3 to 11 The switching unit includes multiple drive motors 10 installed on the outside of the feed frame 5, and the output end of each drive motor 10 is fixedly connected to the inner side of the feed frame 5 through a rotating rod 11. The outer wall of the rotating rod 11 is fixedly connected to a rotating plate 9. The bottom of the second fixed plate 19 has two third fixed plates 30, and the two ends of the third fixed plates 30 are fixedly connected to the inner side of the feed frame 5. The drive motor 10 is controlled by a PLC controller, which can control the intermittent start of the drive motor 10. First, when the operator puts the raw material into the feed inlet of the feed frame 5, the material slides down along the feed inlet. In the initial state, the first set of rotating plates 9 is close to the third fixed plate 30 on the left. At this time, the left channel is closed. The raw material enters the top of the first set of fixed plates 18 from the right, thus feeding. When the inner side of the right conical hole 25 is filled, the PLC controller controls the first set of drive motors 10 to start, thereby driving the output end of the drive motor 10 to rotate, thereby driving the rotating plate 9 to rotate, thus closing the right channel and opening the left channel. This allows the right side to be squeezed without the raw material falling, while the other side can be fed. This realizes continuous feeding operation and eliminates the "time overlap conflict" between feeding and squeezing, realizing "zero waiting" continuous production, thereby improving the squeezing efficiency of the device and improving the overall practicality of the device.

[0021] When the first set of extrusion columns 28 extrudes the raw material, the second set of drive motors 10 controls the left channel to open. When the raw material fills the inside of the left conical hole 25, the second set of drive motors 10 rotates, opening the right channel and closing the other channel, thus switching the channels. This allows for continuous feeding while the second set of extrusion columns 28 is being extruded, eliminating the "time overlap conflict" between feeding and extrusion, achieving "zero waiting" continuous production, improving the extrusion efficiency of the device, and thus improving the overall practicality of the device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
