DETAILED DESCRIPTION Example

[0024] like Figure 1 and Figure 5 As shown, a composite material production and processing equipment includes an extrusion molding mechanism 6 for producing a composite pipe 7, the composite pipe 7 includes a composite fiber 11, an outer tube 13 and an inner tube 14, the composite fiber 11 is cross-linked and wound between the outer tube 13 and the inner tube 14, the side end face of the extrusion molding mechanism 6 is connected to a screw extruder 1, the top of the extrusion molding mechanism 6 is rotatably connected to a spray chamber 5 for pre-treating the composite fiber 11, the upper end face of the spray chamber 5 is fixedly connected to a winding mechanism 2 for cross-linking and winding the composite fiber 11, a plurality of groups of placement chambers 4 are embedded in the winding mechanism 2, and a driving mechanism 3 is provided in the middle of the winding mechanism 2.

[0025] Furthermore, the placement bin 4 is provided with a plurality of groups uniformly embedded in the middle of the winding mechanism 2 , and the interior of the placement bin 4 is rotatably connected with a winding roll 8 wound around the composite fiber 11 .

[0026] When in use, the winding roll 8 wound with the composite fiber 11 is placed inside the placement bin 4, and the composite fiber 11 is wound and cross-linked through the winding mechanism 2 under the drive of the driving mechanism 3, and during the cross-linking process, the composite fiber 11 is sprayed and pre-treated through the spray bin 5 to facilitate the subsequent attachment of thermoplastic parts such as resin. The extrusion molding mechanism 6 adopts graded molding, and is connected to two groups of screw extruders 1 respectively. First, the inner tube 14 is molded and the composite fiber 11 is cross-linked and wound around the outside of the inner tube 14, and then the thermoplastic material is injected for secondary molding to form the outer tube 13, so that the composite fiber 11 is stably arranged between the outer tube 13 and the inner tube 14. Compared with the one-time molding, the composite fiber 11 is located in the middle position, and the structure is more stable. The molding interval between the outer tube 13 and the inner tube 14 is short, and its compatibility is better. There is no obvious stratification, and the composite fiber 11 can be strongly wrapped. Example

[0027] Based on the first embodiment, Figure 1-3 As shown, a spray chamber 12 is opened inside the spray chamber 5, and a pretreatment liquid 21 is carried inside the spray chamber 12. A centrifugal liquid separation chamber 24 is rotatably provided in the middle of the spray chamber 12. A spiral conveying blade 22 is rotatably connected to the middle of the centrifugal liquid separation chamber 24. The bottom of the centrifugal liquid separation chamber 24 is connected to the spray chamber 12, and micropores are provided on the side end surface of the centrifugal liquid separation chamber 24.

[0028] During use, the composite fiber 11 passes through the spray chamber 12 into the interior of the extrusion molding mechanism 6. When the composite fiber 11 is placed in the spray chamber 12, the spray chamber 12 pretreats the composite fiber 11. In order to improve the pretreatment effect of the composite fiber 11 and avoid the precipitation of the pretreatment liquid 21 due to the centrifugal action of the rotation of the winding mechanism 2, a centrifugal liquid separation chamber 24 is provided. The centrifugal liquid separation chamber 24 is rotatably arranged in the spray chamber 12. A spiral conveying blade 22 is provided in the centrifugal liquid separation chamber 24. The spiral conveying blade 22 can transport the pretreatment liquid 21 in the spray chamber 12 to the centrifugal liquid separation chamber 24. The centrifugal liquid separation chamber 24 evenly sprays the pretreatment liquid 21 on the surface of the composite fiber 11 with the centrifugal force of its own rotation, thereby improving the uniformity of the pretreatment of the composite fiber 11 and avoiding the precipitation of the pretreatment liquid 21 due to the centrifugal rotation.

[0029] like Figure 1-4As shown, the driving mechanism 3 includes a driving source 9, a driven gear 23 and a driving gear 29. The driving source 9 is embedded in the middle of the winding mechanism 2. The driving source 9 drives the rotation of the driving rod 10. The driving gear 29 is fixedly connected to the outer end surface of the driving rod 10. The driven gear 23 is meshed with the outer end surface of the driving gear 29. A rotating groove 28 adapted to the driven gear 23 is provided at the bottom of the driving mechanism 3, and a tooth groove 27 meshed with the driven gear 23 is provided on the inner wall of the winding mechanism 2.

[0030] When in use, the driving source 9 drives the driving rod 10 to rotate to move the pretreatment liquid 21 inside the spray chamber 12 upward for stirring. At the same time, the driving gear 29 on the side end face of the driving rod 10 and the transmission of the rotating stirring rod 26 can drive the winding mechanism 2 to rotate, thereby rotating the placement bin 4 inside the winding mechanism 2 to complete the cross-winding of the composite fiber 11.

[0031] like Figure 1-4 As shown, a rotating stirring rod 26 is fixedly connected to the middle of the driven gear 23 , an inclined centrifugal chamber 25 is provided inside the centrifugal liquid separation chamber 24 , and the rotating stirring rod 26 extends through and into the inside of the centrifugal chamber 25 .

[0032] When in use, the driven gear 23 rotates around the driving rod 10 while it rotates itself under the drive of the rotating stirring rod 26, so that the centrifugal liquid separation chamber 24 can be driven to rotate by rotating the stirring rod 26 to connect the centrifugal liquid separation chamber 24, and because the centrifugal liquid separation chamber 24 and the driving rod 10 have a speed difference, the spiral conveying blade 22 can convey the pretreatment liquid 21, and the pretreatment liquid 21 can be conveyed to the centrifugal chamber 25 and then dispersed to the surface of the composite fiber 11 by centrifugation. At the same time, there is also a speed difference between the rotating stirring rod 26 and the winding mechanism 2, so that the spraying effect of the centrifugal liquid separation chamber 24 is more uniform, and the pretreatment liquid 21 inside the centrifugal chamber 25 can be further stirred and mixed by the self-rotation of the rotating stirring rod 26 to prevent the pretreatment liquid 21 from precipitating and deteriorating.

[0033] like Figure 1-2 and Figure 6-7 As shown, a pretreatment chamber 20 is provided at the top of the extrusion molding mechanism 6, and a braiding ring 30 extending to the interior of the pretreatment chamber 20 is provided at the bottom of the spray chamber 5. The composite fiber 11 passes through the braiding ring 30 and extends to the interior of the extrusion molding mechanism 6. The outer end face of the braiding ring 30 is rotatably connected to a rotating ring 32. A connecting cavity 33 is opened inside the braiding ring 30. An extrusion port 18 is provided at the bottom of the braiding ring 30, and the extrusion port 18 is connected to the screw extruder 1 through the connecting cavity 33.

[0034] Furthermore, the interior of the connecting cavity 33 is fixedly connected with a sleeve rod 34 sleeved on the outer end of the composite fiber 11 to prevent the composite fiber 11 from coming into contact with the thermoplastic part and affecting subsequent winding. The extrusion surface of the extrusion port 18 is inclined, and the extrusion direction of the extrusion port 18 is not parallel to the production direction of the composite pipe 7, thereby improving the extrusion molding effect of the composite pipe 7.

[0035] When in use, the screw extruder 1 melts the thermoplastic material and transports it to the extrusion port 18 through the connecting cavity 33, and preforms the inner tube 14 inside the pretreatment chamber 20 through the extrusion port 18. The braiding ring 30 extends inside the pretreatment chamber 20. The braiding ring 30 rotates synchronously with the rotation of the winding mechanism 2, so that the composite fiber 11 inside the braiding ring 30 rotates, and the other end of the composite fiber 11 is fixed in the composite tube 7 inside the extrusion molding mechanism 6, so that the composite fiber 11 will be gradually wound around the outer surface of the inner tube 14 under the rotation effect of the braiding ring 30.

[0036] like Figure 1-2 and Figure 6-7 As shown, a core 15 is provided in the middle of the extrusion molding mechanism 6, and the core 15 extends to the middle of the pretreatment chamber 20. A partition plate 31 is provided inside the pretreatment chamber 20, and the partition plate 31 is arranged to fit the inner side of the composite fiber 11. The extrusion port 18 is fixedly arranged between the partition plate 31 and the core 15, and a cooling channel 17 is provided inside the core 15.

[0037] Furthermore, the cooling channel 17 is distributed at the end of the partition plate 31 , and the end of the partition plate 31 is transitioned through an inclined structure to facilitate the winding of the composite fiber 11 . The thickness of the inner tube 14 is lower than that of the outer tube 13 , which facilitates the initial molding of the inner tube 14 .

[0038] When in use, the braiding ring 30 rotates to first cause the composite fibers 11 to be entangled with each other on the surface of the partition plate 31, and an inner tube 14 is formed between the partition plate 31 and the core 15 through the discharge of the extrusion port 18. After the inner tube 14 is extruded, it is initially cooled and formed through the cooling channel 17. As the composite pipe 7 is continuously extruded, the composite fibers 11 are gradually entangled with the surface of the inner tube 14, so that the composite fibers 11 are evenly wrapped around the outer surface of the inner tube 14.

[0039] like Figure 1-2 and Figure 6-7 As shown, there are two groups of extrusion ports 18 , and the two groups of extrusion ports 18 have different vertical heights, and one group is embedded in the inner wall of the extrusion molding mechanism 6 for molding the outer tube 13 .

[0040] Furthermore, the screw extruder 1 may also be provided with two groups corresponding to the two groups of extrusion ports 18 .

[0041] When in use, after the composite fiber 11 is wound around the outer end surface of the inner tube 14 , the thermoplastic material is injected again through the extrusion port 18 , and the post-injected material wraps the composite fiber 11 and the inner tube 14 to form the outer tube 13 , thereby completing the molding of the composite tube 7 . Example

[0042] On the basis of embodiment 1 or 2, Figure 1-2 As shown in Figures 6-10, a bonding mechanism 19 for flattening and pressing the composite fibers 11 is also provided inside the pretreatment chamber 20. The bonding mechanism 19 is located below the partition plate 31. The bonding mechanism 19 includes a bonding plate 38 and a horizontal reciprocating drive mechanism. The bonding plate 38 is arc-shaped and bonded to the outer end surface of the inner tube 14.

[0043] Furthermore, the bonding plates 38 are provided with a plurality of groups of mutually combined ring-shaped plates, and the bonding plates 38 are provided with an inclined portion adapted to the bottom of the partition plate 31 .

[0044] During use, since the inner tube 14 is initially cooled through the cooling channel 17, the end of the inner tube 14 away from the mold core 15 still has a certain plasticity. The composite fiber 11 is pressed and partially embedded in the surface of the inner tube 14 through the reciprocating movement of the bonding plate 38, thereby improving the stability of the position of the composite fiber 11. The pressing and limiting of the inner tube 14 can avoid the occurrence of overlapping and the like when the composite fiber 11 is wound from the partition plate 31 to the surface of the inner tube 14, thereby improving the uniformity of the winding of the composite fiber 11.

[0045] like Figure 1-2 As shown in Figures 6-10, the horizontal reciprocating drive mechanism includes a driving protrusion 35, a first driving slide 36 and a second driving slide 37. The second driving slide 37 is fixedly connected to the end of the bonding plate 38 away from the inner tube 14. The second driving slide 37 is elastically connected to the inside of the pretreatment chamber 20. The first driving slide 36 and the second driving slide 37 are vertically arranged, and the first driving slide 36 and the second driving slide 37 are inclined to each other. The driving protrusion 35 is fixedly connected to the bottom of the spray chamber 5, and the first driving slide 36 and the driving protrusion 35 are elastically abutted.

[0046] Furthermore, an arc portion 39 is provided between the driving protrusion 35 and the first driving slide plate 36 .

[0047] During use, as the spray chamber 5 rotates, the driving protrusion 35 is driven to rotate continuously relative to the first driving slide 36, and the first driving slide 36 is driven to move downward under the action of the arc portion 39, and the first driving slide 36 and the second driving slide 37 are fitted with the inclined surface, thereby pushing the second driving slide 37 to move horizontally, and the second driving slide 37 is elastically arranged inside the pretreatment chamber 20, and can drive the second driving slide 37 to reset itself under the action of elastic force, thereby realizing the reciprocating drive of the fitting mechanism 19 with the help of the rotation of the spray chamber 5, and the streamlined mechanism can effectively improve the production quality of the composite pipe 7.

[0048] Working principle: The winding roll 8 wound with the composite fiber 11 is placed inside the placement bin 4, and the composite fiber 11 is wound and cross-linked through the winding mechanism 2 under the drive of the driving mechanism 3, and during the cross-linking process, the composite fiber 11 is sprayed and pre-treated through the spray bin 5 to facilitate the attachment of thermoplastic parts such as resin in the later stage. The extrusion molding mechanism 6 adopts graded molding, and is respectively connected with two groups of screw extruders 1. First, the inner tube 14 is molded and the composite fiber 11 is cross-linked and wound around the outside of the inner tube 14, and then the thermoplastic material is continuously injected for secondary molding to form the outer tube 13, so that the composite fiber 11 is stably arranged between the outer tube 13 and the inner tube 14. Compared with the one-time molding, the composite fiber 11 is located in the middle position, and the structure is more stable, and the molding interval between the outer tube 13 and the inner tube 14 is short. The compatibility is good, there is no obvious stratification, and the composite fiber 11 can be strongly wrapped. The composite fiber 11 passes through the spray chamber 12 and enters the interior of the extrusion molding mechanism 6. When the composite fiber 11 is placed in the spray chamber 12, the spray chamber 12 pre-treats the composite fiber 11. In order to improve the pre-treatment effect of the composite fiber 11 and avoid the precipitation of the pre-treatment liquid 21 due to the centrifugal action of the winding mechanism 2, a centrifugal liquid separation chamber 24 is provided. The centrifugal liquid separation chamber 24 is rotatably arranged in the interior of the spray chamber 12. A spiral conveying blade 22 is provided in the centrifugal liquid separation chamber 24. The spiral conveying blade 22 can rotate to transport the pre-treatment liquid 21 in the spray chamber 12 to the interior of the centrifugal liquid separation chamber 24. The centrifugal liquid separation chamber 24 evenly sprays the pre-treatment liquid 21 with the centrifugal force of its own rotation. The pretreatment liquid 21 is sprinkled on the surface of the composite fiber 11 to improve the uniformity of the pretreatment of the composite fiber 11 and avoid the precipitation caused by the centrifugation of the pretreatment liquid 21. The driving rod 10 is driven by the driving source 9 to rotate to move the pretreatment liquid 21 in the spray chamber 12 upward for stirring. At the same time, the winding mechanism 2 can be driven to rotate by the driving gear 29 on the side end face of the driving rod 10 and the transmission of the rotating stirring rod 26, so that the storage bin 4 in the winding mechanism 2 is rotated to complete the cross winding of the composite fiber 11. The driven gear 23 rotates around the driving rod 10 under the drive of the rotating stirring rod 26, and at the same time, it also rotates itself, so that the centrifugal liquid separation bin 24 can be driven to rotate by connecting the centrifugal liquid separation bin 24 through the rotating stirring rod 26. Since the centrifugal liquid separation bin 24 has a speed difference with the driving rod 10, Therefore, the spiral conveying blade 22 can convey the pretreatment liquid 21, and the pretreatment liquid 21 can be conveyed into the centrifugal chamber 25 and then dispersed to the surface of the composite fiber 11 by centrifugation. At the same time, there is a differential speed between the rotating stirring rod 26 and the winding mechanism 2, so that the spraying effect of the centrifugal liquid separation chamber 24 is more uniform, and the pretreatment liquid 21 inside the centrifugal chamber 25 can be further stirred and mixed by the self-rotation of the rotating stirring rod 26 to avoid the precipitation and deterioration of the pretreatment liquid 21. The screw extruder 1 melts the thermoplastic material and conveys it to the extrusion port 18 through the connecting cavity 33, and preforms the inner tube 14 inside the pretreatment chamber 20 through the extrusion port 18. The braiding ring 30 extends inside the pretreatment chamber 20, and the braiding ring 30 rotates synchronously with the rotation of the winding mechanism 2.The composite fiber 11 inside the braiding ring 30 rotates, and the other end of the composite fiber 11 is fixed in the composite tube 7 inside the extrusion molding mechanism 6, so that the composite fiber 11 will be gradually wound around the outer surface of the inner tube 14 under the effect of the rotation of the braiding ring 30. The rotation of the braiding ring 30 first causes the composite fibers 11 to be mutually wound around the surface of the partition plate 31, and the inner tube 14 is formed between the partition plate 31 and the core 15 through the discharge of the extrusion port 18. After the inner tube 14 is extruded, it is initially cooled and formed through the cooling channel 17. As the composite tube 7 is continuously extruded, the composite fiber 11 gradually entangles with the surface of the inner tube 14, so that the composite fiber 11 is evenly wound around the outer surface of the inner tube 14. After the composite fiber 11 is wound around the outer end face of the inner tube 14, the thermoplastic material is injected again through the extrusion port 18, and the injected material wraps the composite fiber 11 and the inner tube 14 to form the outer tube 13, thereby completing the molding of the composite tube 7. Since the inner tube 14 is initially cooled through the cooling channel 17 , the end of the inner tube 14 away from the mold core 15 also has a certain plasticity. The composite fiber 11 is pressed and partially embedded in the surface of the inner tube 14 through the reciprocating movement of the bonding plate 38, thereby improving the stability of the position of the composite fiber 11. The pressing and limiting of the inner tube 14 can avoid the phenomenon of overlapping when the composite fiber 11 is wound from the partition plate 31 to the surface of the inner tube 14, thereby improving the uniformity of the winding of the composite fiber 11. As the spray chamber 5 rotates, the driving protrusion 35 is driven to rotate continuously relative to the first driving slide 36. Under the action of the arc portion 39, the first driving slide 36 is driven to move downward, and the first driving slide 36 is fitted with the second driving slide 37 on the inclined surface, thereby pushing the second driving slide 37 to move horizontally. The second driving slide 37 is elastically arranged inside the pretreatment chamber 20. Under the action of the elastic force, the second driving slide 37 can be driven to reset itself, thereby realizing the reciprocating drive of the bonding mechanism 19 with the help of the rotation of the spray chamber 5. The streamlined mechanism can effectively improve the production quality of the composite pipe 7. ,

[0049] In summary, after the device is installed, the composite fiber 11 is first passed through the braiding ring 30 to pass through the extrusion molding mechanism 6, and the screw extruder 1 is turned on so that the initial stage of the material is carried inside the extrusion molding mechanism 6. Subsequently, as the material is pushed forward and extruded, the composite fiber 11 can be automatically wound. After the winding is completed, the outer tube 13 and the inner tube 14 are extruded through the extrusion molding mechanism 6 to form an integral whole.
