Description

Technical Field

[0001] This invention relates to the field of composite material processing equipment technology, and in particular to a material conveying device for composite material processing. Background Technology

[0002] In the processing and production of composite materials, the material conveying device is one of the indispensable key equipment. Its main function is to transport the composite material raw materials from the storage area to the processing equipment to ensure the continuity and stability of the processing.

[0003] For current material conveying devices, the existing material conveying device for composite material processing disclosed in patent number "CN215665504U" drives the rotating shaft to rotate through the first driving component. The rotating shaft drives the feeding blades to rotate, and then the material is poured into the feeding barrel through the feeding barrel. At this time, the material is driven by the feeding blades to be transported from the left side of the feeding barrel to the right side of the feeding barrel, and finally discharged through the discharge barrel on the right side. The driving component drives the rotating shaft to rotate at the same time, which also drives the stirring shaft to rotate. The rotation of the stirring shaft drives several stirring rollers to rotate at the same time, thereby agitating the material inside the discharge barrel.

[0004] This device can only agitate the conveyed material. Its functional shortcomings are particularly evident when conveying powdery or highly fluid composite materials. Powdered composite materials are susceptible to fluctuations in ambient humidity during storage, causing them to absorb moisture and agglomerate. After entering the transfer and feeding stages before conveying, they will form dense clumps due to external pressure. However, this device lacks an effective dispersing mechanism covering the entire conveying process. It cannot break up the initial clumps before the material enters the conveying channel, nor can it specifically disperse the agglomerated material during the conveying process. As a result, the agglomerated material cannot be effectively processed. These undispersed clumps will enter the processing equipment with the material flow, which will disrupt the uniformity of the raw material mixing and directly affect the quality stability of the processed product.

[0005] Accordingly, this application proposes a material conveying device for composite material processing. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a material conveying device for composite material processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A material conveying device for composite material processing includes a conveyor body, a mounting frame fixedly connected to the side end of the conveyor body, a first motor installed inside the mounting frame, a transmission rod fixedly connected to the output end of the first motor, a spiral blade fixedly connected to the end of the transmission rod away from the first motor, a second motor fixedly connected to the side wall of the conveyor body, a feed hopper provided on the top surface of the conveyor body, and a discharge port provided on the bottom surface of the conveyor body. The transmission rod is provided with a lifting and rotating part, which consists of a lifting component and a rotating component. The lifting component is used to clear the material in the feed hopper, and the rotating component is used to initially disperse the falling material. The spiral blade is provided with a dispersing telescopic part, which consists of a telescopic component and a dispersing component. The dispersing component is used to disperse clumps in the material, and the telescopic component is used to change the position of the dispersing component.

[0008] Preferably, the lifting component and the rotating component are linked by a transmission assembly, which synchronously drives the lifting component and the rotating component to operate when the rotating rod rotates.

[0009] Preferably, the lifting component, driven by the transmission assembly, continuously moves up and down within the feed hopper to clear the material in the feed hopper.

[0010] Preferably, the rotating component, driven by the transmission assembly, will rotate in the opposite direction to the spiral blades, thereby generating a reverse thrust that pushes the falling material into the spiral blades. At the same time, during the pushing process, the material can also be initially dispersed.

[0011] Preferably, the disassembly component and the telescopic component are linked by a drive assembly, which drives the disassembly component and the telescopic rod to operate on the spiral blades synchronously through the rotation of the second motor.

[0012] Preferably, the dispersing component rotates in the gap between the spiral blades under the transmission of the drive assembly, so as to fully disperse the material on the spiral blades.

[0013] Preferably, under the drive of the drive assembly, the telescopic component causes the disintegrating component to reciprocate up and down on the spiral blade, thereby changing the position of the disintegrating component on the spiral blade.

[0014] Preferably, the dispersing component is provided with an extension component, which expands the dispersing area by the centrifugal force generated when the dispersing component rotates.

[0015] The present invention has the following beneficial effects: 1. The present invention sets a dispersing telescopic part inside the spiral blade, and realizes the linkage between the dispersing part and the telescopic part through the driving component. The dispersing part rotates in the gap between the spiral blades, which can fully disperse the material. The telescopic part drives the dispersing part to move up and down reciprocally, changing the position of the dispersing part, avoiding the formation of dispersing dead corners, improving the fullness and uniformity of dispersing, and solving the problems of poor dispersing effect and low flexibility of existing material conveying devices.

[0016] 2. This invention sets up a lifting and rotating part and uses a transmission component to realize the linkage between the lifting part and the rotating part. The lifting part can continuously move up and down in the feeding hopper, effectively preventing the material from accumulating and blocking in the feeding hopper and ensuring that the material falls smoothly. The rotating part rotates in the opposite direction to push the material into the spiral blades and initially disperse the material, which solves the problems of easy blockage of the feeding hopper and poor initial dispersion effect of the existing material conveying device.

[0017] 3. The present invention sets an extension component on the dispersing component, which uses the centrifugal force generated by the rotation of the dispersing component to expand the dispersing area, thereby improving the dispersing efficiency and the adaptability of the device to different amounts of materials.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1:

[0021] Reference Figures 1 to 10 A material conveying device for composite material processing includes a conveyor body 1, a mounting frame 2 fixedly connected to the side end of the conveyor body 1, a first motor 3 installed inside the mounting frame 2, a transmission rod fixedly connected to the output end of the first motor 3, a spiral blade 5 fixedly connected to the end of the transmission rod away from the first motor 3, a second motor 6 fixedly connected to the side wall of the conveyor body 1, a feed hopper 7 provided on the top surface of the conveyor body 1, and a discharge port 8 provided on the bottom surface of the conveyor body 1. The transmission rod is equipped with a lifting and rotating part, which consists of a lifting component and a rotating component. The lifting component is used to clear the material in the feed hopper 7, and the rotating component is used to initially disperse the falling material. The lifting component and the rotating component are linked by a transmission assembly. When the rotating rod 4 rotates, the transmission assembly synchronously drives the lifting component and the rotating component to operate. Driven by the transmission assembly, the lifting component continuously moves up and down in the feed hopper 7, thereby clearing the material in the feed hopper 7. Driven by the transmission assembly, the rotating component will rotate in the opposite direction to the spiral blade 5, thereby forming a reverse thrust, pushing the falling material into the spiral blade 5. At the same time, during the pushing process, the material can also be initially dispersed.

[0022] In this embodiment, as Figures 2 to 5 , Figure 7 As shown, the lifting and rotating part in this embodiment can be implemented by designing the following structure: The transmission assembly consists of a first gear 41, a first transmission wheel 42, a rotating rod 45, a second gear 46, a second transmission wheel 47, and a transmission belt 48. The first gear 41 is fixedly connected to the rotating rod 4, the first transmission wheel 42 is rotatably connected to the rotating rod 4, the rotating rod 45 is rotatably connected to the mounting bracket 2, the second gear 46 is fixedly connected to the rotating rod 45, the first gear 41 and the second gear 46 mesh with each other, the second transmission wheel 47 is fixedly connected to the rotating rod 45, and the transmission belt 48 is wound around the first transmission wheel 42 and the second transmission wheel 47 respectively.

[0023] Specifically, through the meshing transmission of the first gear 41 and the second gear 46, due to the reverse transmission characteristics of gear meshing, the rotating rod 45 driven by the second gear 46 rotates in the opposite direction to the rotating rod 4. At the same time, the rotating rod 45 drives the second transmission wheel 47 to rotate. Through the belt transmission between the second transmission wheel 47 and the first transmission wheel 42, the rotating components (sleeve 43 and stirring column 44) driven by the first transmission wheel 42 rotate in the opposite direction to the spiral blade 5. The reverse rotation design can enhance the relative force during material conveying and dispersing, avoiding the slippage of materials caused by co-rotation, and improving the dispersing efficiency of the stirring column 44 on the materials, reducing the risk of material accumulation.

[0024] The lifting component consists of a shaped wheel 49, a spring telescopic rod 410, a horizontal plate 411, and a push rod 412. The shaped wheel 49 is fixedly connected to the end of the rotating rod 45, and the spring telescopic rod 410 is symmetrically fixedly connected inside the conveyor body 1. The circumferential surface of the shaped wheel 49 is provided with a protruding structure. When the rotating rod 45 drives the shaped wheel 49 to rotate, the protrusion rotates synchronously with the shaped wheel 49. When the protruding part contacts the horizontal plate 411, it generates an upward thrust, pushing the horizontal plate 411 and the telescopic end of the spring telescopic rod 410 to move upward. When the protrusion moves away from the horizontal plate 411, the restoring force of the spring telescopic rod 410 pulls the horizontal plate 411 downward, thereby ensuring that the horizontal plate 411 drives the push rod 412 to move up and down smoothly and accurately pushes the material in the feed hopper 7, improving the anti-blocking effect.

[0025] Specifically, the horizontal plate 411 is fixedly connected to the telescopic ends of the two spring telescopic rods 410, connecting the two spring telescopic rods 410 in series. This symmetrical connection design allows the horizontal plate 411 to simultaneously receive the supporting and restoring forces of the spring telescopic rods 410 on both sides when under force, preventing the horizontal plate 411 from tilting due to force on one side. This ensures smooth operation when the horizontal plate 411 drives the push rod 412 to move up and down, pushing the material in the feed hopper 7 and improving the anti-clogging effect.

[0026] The push rod 412 is fixedly connected to the top surface of the horizontal plate 411. Both the upper and lower sides of the push rod 412 are designed as inclined surfaces, and the push rod 412 is precisely set at the center of the feed hopper 7. This design allows the material to slide smoothly down the inclined surfaces on both sides of the push rod 412 when the push rod 412 moves up and down with the horizontal plate 411 to clear the material. This not only avoids the accumulation of material on the surface of the push rod 412, but also prevents the accumulated material from creating resistance to the push rod 412 and hindering its movement.

[0027] The rotating component consists of a sleeve 43 and a stirring column 44. The sleeve 43 is fixedly connected to the side wall of the first transmission wheel 42. The end of the spiral blade 5 is placed inside the sleeve 43 and rotates. Therefore, the sleeve 43 will rotate in the opposite direction along the spiral blade 5 under the drive of the transmission component, and the two do not interfere with each other. The stirring column 44 is arranged in a ring on the sleeve 43. Multiple stirring blocks are provided on the stirring column 44. The stirring blocks can cut and break up the material. At the same time, when the stirring blocks rotate in the opposite direction, they will apply a thrust to the material to avoid blockage at the feed point.

[0028] In this embodiment, after the material enters the device through the feed hopper 7, the first motor 3 starts and drives the rotating rod 4 to rotate. The rotating rod 4 drives the coaxial spiral blade 5 to rotate synchronously, stably conveying the material to the discharge port 8. During this process, the rotating rod 4 synchronously drives the first gear 41 at its end to rotate. Through meshing transmission with the second gear 46, the second gear 46 is forced to rotate and drives the rotating rod 45 to rotate. The irregularly shaped wheel 49 fixed at the top of the rotating rod 45 rotates together with the rotating rod 45. When the protruding part of the irregularly shaped wheel 49 contacts the upper horizontal plate 411, it will generate an upward thrust on the horizontal plate 411, causing the horizontal plate 411 to move upward and squeeze the spring telescopic rod 410 at the top. As the horizontal plate 411 moves upward, it drives the push rod 412 connected to it to rise synchronously, creating an upward pushing effect on the material at the top of the feed hopper 7. When the protruding part of the irregular wheel 49 rotates to a position away from the horizontal plate 411, the spring telescopic rod 410, under the action of its own elastic restoring force, pulls the horizontal plate 411 downward to return to its initial position, and the push rod 412 also moves downward synchronously. Through this reciprocating motion, the bridging phenomenon of material in the feed hopper 7 can be effectively prevented, avoiding blockage of the feed channel.

[0029] In addition, when the rotating rod 45 rotates, it will also drive the coaxial second transmission wheel 47 to rotate synchronously. The second transmission wheel 47 transmits power to the first transmission wheel 42 through the transmission belt 48, so that the first transmission wheel 42 drives the sleeve 43 to rotate. The stirring column 44 on the sleeve 43 rotates together with the sleeve 43, and performs preliminary dispersing treatment on the material falling into the feed hopper 7, further preventing the material from accumulating at the feed end of the spiral blade 5 and ensuring the continuity of material conveying. Example 2:

[0030] Reference Figure 6 , Figure 8 ,Figure 9 This embodiment also includes the following further features: the interior of the spiral blade 5 is provided with a dispersing telescopic part, and multiple dispersing telescopic parts are provided. The specific number of these parts needs to be flexibly adjusted according to the actual specifications of the equipment (such as the number and spacing of the spiral blades 5) to ensure that the gap between each spiral blade 5 is equipped with a corresponding dispersing telescopic part, so that the dispersing action can accurately cover the gap area between the blades, avoid material accumulation due to the lack of corresponding dispersing parts in the gap, further ensure that the material is dispersed without dead corners in the conveying path, and improve the overall conveying and dispersing efficiency.

[0031] The dispersing telescopic part consists of a telescopic component and a dispersing component. The dispersing component is used to break up lumps in the material, and the telescopic component is used to change the position of the dispersing component. The dispersing component and the telescopic component are linked by a drive assembly. The drive assembly drives the dispersing component and the telescopic rod to operate on the spiral blade 5 synchronously through the rotation of the second motor 6. Under the drive of the drive assembly, the telescopic component causes the dispersing component to move up and down on the spiral blade 5, thereby changing the position of the dispersing component on the spiral blade 5.

[0032] In this embodiment, the solution can be achieved by structurally designing the telescopic components and drive assembly in the disassembled telescopic section as follows: The drive assembly consists of a first rotating column 61, a third gear 601, a first bevel gear 62, a support plate 63, a short shaft 64, a second bevel gear 65, a second rotating column 66, and a fourth gear 661. The first rotating column 61 is fixedly connected to the output end of the second motor 6 and is rotatably connected to the spiral blade 5. The third gear 601 is fixedly connected to the first rotating column 61, the first bevel gear 62 is fixedly connected to the first rotating column 61, the support plate 63 is fixedly connected to the inner wall of the spiral blade 5, the short shaft 64 is rotatably connected to the side wall of the support plate 63, the second bevel gear 65 is fixedly connected to the short shaft 64, and the first bevel gear 62 and the second bevel gear 65 mesh with each other. The second rotating column 66 is rotatably connected to the inner wall of the spiral blade 5, the fourth gear 661 is fixedly connected to the second rotating column 66, and the third gear 601 and the fourth gear 661 mesh with each other.

[0033] The telescopic component consists of a disc 641, a protruding rod 611, a connecting rod 612, a rotating shaft 613, and a sliding rod 614. The disc 641 is fixedly connected to the short shaft 64, the protruding rod 611 is fixedly connected to the eccentric part of the disc 641, the connecting rod 612 is hinged to the protruding rod 611, and a circular protrusion is provided at the end of the connecting rod 612 away from the protruding rod 611. The rotating shaft 613 is rotatably connected to the top surface of the circular protrusion, and the sliding rod 614 is fixedly connected to the end of the rotating shaft 613 away from the circular protrusion. A retaining strip is provided on the sliding rod 614.

[0034] Specifically, the sliding rod 614 can rotate on the circular protrusion when sliding up and down via the rotating shaft 613. At the same time, the sliding rod 614 can move up and down under the drive of the connecting rod 612 via the rotating shaft 613 without affecting the rotation.

[0035] In this embodiment, the first rotating column 61 is driven to rotate by the second motor 6, and the first bevel gear 62, which is fixed to the outside of the first rotating column 61, rotates synchronously with it and transmits power through meshing with the second bevel gear 65. When the second bevel gear 65 is rotated under force, it drives the short shaft 64, which is coaxial with it, to rotate stably on the support plate 63. At the same time, the disc 641 fixed on the short shaft 64 also rotates with the short shaft 64. During the rotation of the disc 641, the convex rod 611 and the connecting rod 612 connected at its eccentric position move eccentrically, and drive the sliding rod 614 at the top to move up and down inside the dispersing component through the rotating shaft 613, thereby dynamically changing the dispersing position of the dispersing component on the material and improving the dispersing uniformity. Simultaneously, when the first rotating rod 45 rotates, its externally fixed third gear 601 meshes with the adjacent fourth gear 661; after the fourth gear 661 rotates under force, it drives the second rotating column 66 to rotate synchronously, and the second rotating column 66 further drives the entire dispersing component to rotate. Through the rotation of the dispersing component, the material remaining in the gap of the spiral blade 5 can be specifically dispersed, preventing the material from accumulating in the gap and further ensuring the smoothness of material conveying. Example 3:

[0036] In this embodiment, the dispersing component rotates in the gap between the spiral blades 5 under the transmission of the driving component, so as to fully disperse the material on the spiral blades 5. The dispersing component is provided with an extension component, which expands the dispersing area by the centrifugal force generated when the dispersing component rotates.

[0037] like Figure 9 and Figure 10 As shown, the disassembly component in the disassembly and expansion joint can be implemented using the following specific structure to achieve the technical solution of the embodiment: The disassembled component consists of a worm gear 67, a connecting plate 68, a support shaft 69, a worm wheel 610, a cylindrical seat 615, a round rod 616, and a turntable 617. The worm gear 67 is fixedly connected to the second rotating rod 45. The connecting plate 68 is fixedly connected to the inner wall of the spiral blade 5. The support shaft 69 is rotatably connected to the top surface of the connecting plate 68. The worm wheel 610 is rotatably connected to the top surface of the support shaft 69. The worm gear 67 and the worm wheel 610 mesh with each other. The worm wheel 610 has a groove that matches the retaining strip on the sliding rod 614. When the telescopic component drives the sliding rod 616... When the 14 moves up and down along the axial direction, the meshing relationship between the slot and the strip will not be broken, so that the rotational motion of the worm gear 610 can be synchronously transmitted to the sliding rod 614 through the meshing of the slot and the strip, ensuring that the sliding rod 614 can still rotate with the worm gear 610 while moving up and down; on the other hand, the slot forms a radial constraint on the strip, which can provide a stable guide for the up and down movement of the sliding rod 614, effectively limiting the radial offset or wobbling of the sliding rod 614 during the movement, and ensuring the stability of the linkage between the sliding rod 614 and the turntable 617.

[0038] The cylindrical seat 615 is fixedly connected to the spiral blade 5, the round rod 616 is slidably connected inside the cylindrical seat 615, the round rod 616 is fixedly connected to the sliding rod 614, and the turntable 617 is fixedly connected to the top of the round rod 616.

[0039] The extension assembly consists of a hinge block 618, a hinge rod 619, and an arc-shaped piece 620. The hinge block 618 is arranged in a ring at the bottom of the turntable 617. The hinge rod 619 is hinged to the hinge block 618, and the arc-shaped piece 620 is hinged to the end of the hinge rod 619 away from the hinge block 618. The arc-shaped piece 620 adopts an arc-shaped curved surface design, and its curvature is adapted to the rotation trajectory of the turntable 617. On the one hand, it can reduce the resistance when the material impacts, and prevent the material from accumulating on the surface of the arc-shaped piece 620; on the other hand, the curved surface structure can transmit the dispersing force to the material more evenly, improving the dispersing effect. In this embodiment, during the rotation of the second rotating column, the worm gear sleeved on its outside rotates together, and the power is transmitted through meshing with the worm wheel; when the worm wheel is subjected to force and rotates, it drives the sliding rod to rotate synchronously by means of the cooperation of the groove in its own structure and the locking strip on the sliding rod. The turntable connected to the top of the sliding rod rotates together with the sliding rod. Under the action of centrifugal force generated by the rotation of the turntable, the hinge rod and arc plate at the bottom of the turntable are gradually thrown outward. The hinge rod will unfold around the hinge point, and the arc plate will extend outward from the initial position at the bottom of the turntable, thus expanding the range of material dispersion by the turntable and further improving the comprehensiveness of material dispersion.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. 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.
