Description

Technical Field

[0001] This invention relates to a granulation apparatus for composite fiber materials, and more particularly to a granulation apparatus for composite fiber materials. Background Technology

[0002] In waste recycling, composite fiber materials are an important direction for realizing the high-value utilization of resources. The granulation process is a key step in this utilization path, and its efficiency directly determines the production rhythm and capacity of composite fiber materials. Currently, the waste recycling and granulation process for composite fiber material preparation often adopts a step-by-step collaborative processing mode with multiple different devices. This not only significantly increases the cost of equipment purchase and maintenance, but also occupies a large amount of factory space due to the multiple devices, indirectly affecting the overall production flow efficiency of the factory. To solve this problem, a film edge-cutting waste granulation device is disclosed in Chinese Patent No. CN221339119U. This device optimizes the utilization rate of the collection space to a certain extent by integrating cutting, granulation, and material collection shaking structures. However, in the granulation application scenario of composite fiber material preparation, there is still a core problem of low granulation efficiency, which is difficult to meet the needs of large-scale production of composite fiber materials. Specifically, existing integrated granulation equipment lacks a targeted and efficient granulation and cutting structure design for the granulation process of composite fiber materials. The granulation process mainly relies on the material's own gravity to move the material downwards and for subsequent processing, resulting in slow material flow and forming rhythm. Furthermore, in the material pretreatment stage required for composite fiber material granulation, existing equipment lacks a real-time feeding and stirring structure, leading to a cumbersome and inconvenient feeding process, insufficient material supply continuity, and a tendency for material accumulation and uneven mixing, further exacerbating the lag in the granulation rhythm. More importantly, when the waste material is not completely melted, the fluidity of the molten material is inherently poor, and existing equipment lacks corresponding auxiliary pushing and accelerating forming structures, resulting in extremely low flow efficiency of the incompletely melted material within the granulation channel. This directly leads to a prolonged granulation forming cycle and a decrease in forming efficiency. All these factors combined result in low efficiency of existing granulation equipment in the granulation stage of composite fiber material preparation from waste recycling. Therefore, the existing technology has certain defects and shortcomings, necessitating its design improvement. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are: Firstly, in this invention, during the application of this technical solution, by setting up a linked stirring module and a feeding module, feeding and stirring can be carried out simultaneously during use. At the same time, with the help of the auxiliary heating and stirring crushing function of the stirring rack, the raw material temperature is raised in advance and the raw material is prevented from accumulating and clumping, ensuring a continuous and stable supply of raw materials, thereby improving the efficiency of raw material pretreatment.

A feeding module 44 is fixedly installed on the upper end of the can-shaped hopper 43 on the side away from the screw extrusion mechanism 3.

On one side of the feeding mechanism 4, the second synchronous wheel 332 is connected to the end of the extrusion auger 32 near the feeding mechanism 4 via a sealed coupling. The second synchronous wheel 332 and the first synchronous wheel 335 are connected by a synchronous belt drive. The heating wires on the inner wall of the main pipe 31 can achieve uniform heating of the raw material, ensuring that the raw material is fully melted and the temperature is stable. The extrusion auger 32 inside the main pipe 31 can form a continuous pushing force on the raw material and molten material, avoiding the material from accumulating in the pipe and ensuring smooth and efficient conveying. The first motor 334 in the drive module 33 provides stable power output for the entire screw extrusion mechanism 3. With the transmission cooperation of the first synchronous wheel 335, the second synchronous wheel 332 and the synchronous belt, power can be accurately transmitted and losses can be reduced, ensuring the smoothness and consistency of the rotation of the extrusion auger 32, which can improve the reliability and operating efficiency of the melt extrusion link in the granulation process.

[0018] Please see Figures 3-5 and Figure 7The forming mechanism 5 includes a granulation extrusion head 51 and a transmission module 52. The transmission module 52 is fixedly installed on the side of the base frame 2 away from the feeding mechanism 4. The granulation extrusion head 51 is fixedly installed at the output end of the main pipe 31 away from the feeding mechanism 4. Granulation extrusion holes 53 are evenly spaced at the bottom of the granulation extrusion head 51. A cutter module 56 is rotatably connected to the bottom of the granulation extrusion head 51. The cutter module 56 is connected to the extrusion auger 32 driven by the transmission module 52 and the drive module 33. The transmission module 52 includes a guide rail 521, which is fixedly installed on the side of the base frame 2 away from the feeding mechanism 4. A guide slider 522 is slidably connected inside the guide rail 521. A hinge frame 523 is fixedly installed on the outside of the guide slider 522. The top of the forming mechanism 3 is hinged to a linkage plate 524, and the top of the linkage plate 524 is hinged to a rotating disk 525. The end of the rotating disk 525 away from the linkage plate 524 is rotatably connected to the outer end of the main pipe 31. The end of the rotating disk 525 away from the linkage plate 524 is connected to the outer end of the extrusion auger 32 through a sealed coupling. A rack 526 is fixedly installed at the lower end of the hinge frame 523. A first gear 527 is rotatably connected to the bottom center of the guide rail 521.

The forming mechanism 5 also includes a cooling pool 54, which is fixedly installed on the base frame 2 away from the feeding mechanism 4. At one end, water inlet and outlet pipes are provided on both sides of the cooling pool 54. A cooling collection screen box 55 is placed inside the cooling pool 54.

The fourth synchronous wheel 562 and the third synchronous wheel 528 are connected by a synchronous belt drive. Granulation cutters 563 are fixedly installed in a ring at equal intervals on the outer surface of the connecting shaft 561. By setting the granulation extrusion holes 53 at equal intervals at the bottom of the granulation extrusion head 51, the molten material can form regular strips. The cutting module 56, with its granulation cutters 563 arranged in a ring at equal intervals, provides a good foundation for subsequent cutting and shaping. This allows for uniform cutting of strip-shaped materials, ensuring consistent particle size. The guide rail 521 and guide slider 522 of the transmission module 52 provide precise guidance for the movement of the articulated frame 523, ensuring smooth and unbiased power transmission. The meshing transmission between the rack 526 and the first gear 527 enables efficient power conversion. The third synchronous pulley 528 and the fourth synchronous pulley 562, connected by a synchronous belt, ensure the accuracy of cutting power transmission, enabling the cutting module 56 and the extrusion auger 32 to achieve synchronous extrusion and cutting, improving granulation efficiency. The cooling tank 54 quickly reduces the temperature of the cut particles, helping them to set.The inlet and outlet water pipes maintain a stable temperature within the cooling pool 54, ensuring uniform cooling. The detachable cooling collection mesh box 55 facilitates the collection and cleaning of the formed granules, and its top bridge-type handrail makes operation easier. This allows the forming mechanism 5 to achieve efficient integration of material forming, cutting, cooling, and collection, improving granulation efficiency.

[0019] Please see Figure 6 and Figure 8 The agitation module 45 includes an annular top rail 451, which is fixedly installed on the top of the tank-shaped silo 43. A slip ring 452 is slidably connected inside the annular top rail 451, and a spur gear ring 453 is fixedly installed on the top of the slip ring 452. A side mounting bracket 454 is provided at one end of the outer side of the annular top rail 451, and a second motor 455 is fixedly installed on the top of the side mounting bracket 454. A second gear 456 is fixedly installed at the output end of the second motor 455, and the second gear 456 meshes with the spur gear ring 453. A cross 457 is fixedly installed on the inner side of the slip ring 452, and an agitator 458 is fixedly installed in the middle of the cross 457. The feeding module 44 includes a feeding main pipe 441 and a bevel gear. Ring 442 and feeding main pipe 441 are installed at an incline on the upper side of one side of the can-shaped silo 43. Feed pipe 443 is fixedly installed on the upper side of the feeding main pipe 441 near the can-shaped silo 43. The output end of feed pipe 443 is connected to the upper end inside the can-shaped silo 43. Feeding auger 444 is rotatably connected inside the feeding main pipe 441. Connecting shaft 445 is rotatably connected to the top of the feeding main pipe 441. The bottom of connecting shaft 445 is connected to the top of feeding auger 444 through a sealed coupling. Bevel gear 446 is fixedly installed on the top of connecting shaft 445. Bevel gear ring 442 is fixedly installed on the outside of straight gear ring 453. Bevel gear ring 442 and bevel gear 446 are meshed.

[0020] The feeding module 44 also includes a bottom feeding pipe 447, which is fixedly installed at the bottom input end of the feeding main pipe 441. A feeding guide hopper 448 is fixedly installed at the top of the bottom feeding pipe 447. The mixing frame 458 includes a mixing spindle 4581, which is fixedly installed in the middle of the cross 457. Mixing plates 4582 are fixedly installed at equal intervals on the outer surface of the mixing spindle 4581. An electric heating plate 4583 is fixedly connected to the outer surface of the mixing plate 4582. A mixing auger 4584 is fixedly installed at the bottom of the mixing plate 4582. By setting the annular top rail 451 of the mixing module 45 to cooperate with the slip ring 452, a stable rotation base can be provided for the spur ring 453 and the cross 457. The second motor 455 drives the second gear 456 to mesh with the spur ring 453, which can drive the stirring frame 458 to operate efficiently. The stirring plate 4582 and the stirring auger 4584 on the stirring main shaft 4581 can fully stir the raw materials and avoid accumulation and clumping. The electric heating plate 4583 on the stirring plate 4582 can help preheat the raw materials and improve the subsequent melting efficiency. The feeding guide hopper 448 and the bottom feeding pipe 447 of the feeding module 44 can guide the raw materials to smoothly enter the feeding main pipe 441. The feeding auger 444 can realize the directional and precise delivery of raw materials. The meshing transmission of the bevel ring 442 and the bevel gear 446 allows the feeding and stirring to be carried out simultaneously without the need for an additional drive structure. This simplifies the layout while ensuring the continuity and stability of the raw material supply.

[0021] The working principle of this invention is as follows: During application, the drive module 33 and the second motor 455 of this device are first started. After the various operating parameters of the equipment stabilize and enter the preset working state, the raw materials for preparing composite fiber materials are uniformly poured into the feeding guide hopper 448 of the feeding module 44. By setting the feeding guide hopper 448, the raw materials can be accurately gathered and enter the bottom feeding pipe 447. Then, with the guidance of the bottom feeding pipe 447, they smoothly enter the main feeding pipe 441. Since the stirring module 45 and the feeding module 44 maintain a transmission connection, after the second motor 455 is running, its output end will directly drive the second gear 456. Stable rotation, the second gear 456 and the spur ring 453 form a precise meshing transmission, allowing the slip ring 452 to slide smoothly along the annular top rail 451. The annular top rail 451 acts as a limit guide for the slip ring 452, preventing it from deviating during sliding. As the slip ring 452 slides, it synchronously drives the cross 457 to rotate. The cross 457 then drives the mixing frame 458 to rotate synchronously inside the tank-shaped hopper 43, achieving comprehensive agitation of the raw materials within the hopper. The mixing frame 458 includes a mixing main shaft 4581, which is fixedly installed in the middle of the cross 457. When 581 rotates, it drives the stirring plates 4582, which are fixed at equal intervals on its outer surface, to rotate synchronously. The electric heating plates 4583 fixed on the outer surface of the stirring plates 4582 can simultaneously provide auxiliary heating to the raw materials during the stirring process, raising the raw material temperature in advance and laying the foundation for the subsequent melting process. At the same time, the stirring auger 4584 fixed at the bottom of the stirring plates 4582 will rotate together with the stirring plates 4582, further enhancing the stirring and crushing effect on the raw materials, and assisting in the downward movement of the material, effectively preventing the raw materials from accumulating and agglomerating in the canister hopper 43. Meanwhile, the conical toothed ring 442 on the outer side of the straight toothed ring 453 will rotate synchronously with the straight toothed ring 453. The bevel gear ring 442 rotates precisely and meshes with the bevel gear 446 at the top of the connecting shaft 445, thereby driving the connecting shaft 445 to rotate stably. The connecting shaft 445 drives the feeding auger 444 to rotate through the sealed coupling. The rotation of the feeding auger 444 generates continuous conveying power, which smoothly conveys the raw material in the feeding main pipe 441 upward along the pipeline. The raw material is accurately fed into the can-shaped hopper 43 through the feed pipe 443, realizing the continuous and stable feeding of the raw material. The raw material temporarily stored in the can-shaped hopper 43 will fall smoothly into the feeding cylinder 41 through the feeding hopper 42 under its own gravity and the pushing action of the stirring frame 458, and finally accurately enter the screw extrusion mechanism 3.

[0022] After the raw material enters the main pipe 31 of the screw extrusion mechanism 3, the first motor 334 of the drive module 33 will start running. The fixed seat 333 on the top of the mounting plate 331 provides stable support for the first motor 334, ensuring that the first motor 334 does not shake during operation. The output end of the first motor 334 drives the first synchronous pulley 335 to rotate at high speed. The first synchronous pulley 335 forms an efficient transmission with the second synchronous pulley 332 through the synchronous belt. The synchronous belt can ensure the stability and accuracy of power transmission. The second synchronous pulley 332 drives the extrusion auger 32 to rotate inside the main pipe 31 through the sealed coupling. During the rotation of the extrusion auger 32, A continuous and uniform pushing force is applied to the raw material in the main pipe 31, propelling it smoothly towards the output end. Simultaneously, the heating wire on the inner wall of the main pipe 31 is energized and heats up, rapidly raising and maintaining the temperature within the main pipe 31. This uniformly heats the raw material, causing it to gradually melt and form a uniform molten material during its movement. The extrusion auger 32 continuously pushes the molten material towards the output end of the main pipe 31. During this process, the extrusion auger 32 also stirs and homogenizes the molten material, ensuring uniform composition and temperature, ultimately completing the melt extrusion process.

[0023] After the molten material smoothly enters the granulation extrusion head 51 of the forming mechanism 5 from the output end of the main pipe 31, it is guided by the internal channel of the granulation extrusion head 51 and extruded through the granulation extrusion hole 53 at the bottom to form a uniform strip-shaped material. During this process, the end of the extrusion auger 32 away from the drive module 33 drives the rotating disk 525 to rotate synchronously through the sealed coupling. When the rotating disk 525 rotates, it drives the top hinged linkage plate 524 to move back and forth through the hinge point. The linkage plate 524 drives the hinge frame 523 to move synchronously through the hinge point at the bottom, thereby driving the guide slider 522 to slide smoothly back and forth along the guide rail 521. The guide rail 521 provides precise guidance for the guide slider 522, ensuring that the guide slider 522 does not deviate during the sliding process. When the guide slider 522 slides, it drives the rack 526 fixed on one side to move back and forth synchronously. The rack 526 and the first gear 527 in the middle of the bottom of the guide rail 521 form a precise meshing transmission, so that the first gear 527 drives the bottom... The fixed third synchronous wheel 528 reciprocates, and the third synchronous wheel 528 forms a high-efficiency transmission with the fourth synchronous wheel 562 of the cutter module 56 through a synchronous belt, thereby driving the connecting shaft 561 to rotate stably. The connecting shaft 561 drives the granulation cutter 563, which is arranged in a ring at equal intervals on its outer surface, to reciprocate and rotate synchronously. The rotating granulation cutter 563 will quickly cut the strip-shaped material that has just been extruded from the granulation extrusion hole 53, avoiding the formation of strip-shaped materials and promoting the formation of uniformly sized granules. The cutting process is synchronized with the extrusion process to ensure that the length of the granules is consistent. The granulation cutter 563 is a double-edged cutter. During use, the granulation cutter 563 performs alternating forward and reverse cutting. Compared with unidirectional continuous rotation, this method can effectively utilize the double-sided cutting edge of the blade and avoid the problem of long fiber materials being wrapped in one direction on the cutter shaft. At the same time, the granulation cutter 563 is a double-edged cutter. During use, it reciprocates and rotates to perform two-edged cutting, and its overall cutting life is also longer.

[0024] It should be added that during the application of this technical solution, the first synchronous pulley 335, the second synchronous pulley 332, the third synchronous pulley 528, the fourth synchronous pulley 562 and their matching synchronous belts can be driven by a combination of chain and sprocket, or by a synchronous pulley with an internal first gear 527 and its synchronous belt, to ensure transmission stability and accuracy.
