Description

Technical Field

[0001] This invention relates to the field of bundling device technology, and in particular to a device and method for uniformly bundling short fiber bundles. Background Technology

[0002] Existing short fiber bundle uniform bundling devices typically consist of core components such as a guide frame, a splitting rod, multiple tension regulators, and a bundling bell mouth. The guide frame guides multiple strands of fiber from the fiber container out in an orderly manner along a set path. The splitting rod isolates the strands from each other to prevent tangling. The tension regulators independently and precisely control the tension of each strand of fiber using springs, counterweights, or pneumatic methods. Finally, the bundled bell mouth smoothly gathers the strands with consistent tension into a tight, round large bundle. This effectively eliminates tension differences between strands, ensuring neat fiber arrangement and uniform linear density after bundling. It significantly reduces fiber breakage and fuzz in subsequent drafting processes, thereby improving the strength and evenness of the finished yarn. At the same time, it reduces downtime and raw material loss, achieving efficient and stable operation of the short fiber bundling process. Existing short fiber tow uniform bundling devices typically include a fixedly installed guide assembly, a tow detection assembly, and a tension assembly. The relative positions of these components are fixed, and the guiding path and tension of the tow are primarily determined by a fixed number of guide rings, guide rollers, and tension adjustment rods. However, in actual production, the bus density of the tow needs to be flexibly adjusted according to product specifications. This means that the number of short fiber tows involved in bundling will frequently change. Existing bundling devices lack effective flexibility in adapting to different tow numbers, particularly in the arrangement of the guide path and the range of tension adjustment. They can usually only be optimized for a fixed number of tows. When the number of tows changes, the original guide structure cannot be easily adjusted to accommodate the orderly guidance of the new number of tows. Simultaneously, the tensioning mechanism struggles to apply uniform and individually adjustable tension to each tow, resulting in poor tension consistency between different tows. This not only affects the uniformity and forming quality of the bundled tow but also limits the flexibility of the production line and product changeover efficiency, making it difficult to meet the needs of flexible bundling processing of multiple varieties and small batches of short fiber tows.

Detailed Implementation

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] In the description of this invention, it should be understood that "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Please see Figures 1 to 9This invention provides a short fiber tow uniform bundling device: including a mounting base 101, a bundling main body mechanism 102, a fixing guide plate 103, and a guiding and adjusting assembly. The guiding and adjusting assembly includes a splicing guide plate 104, a side hole sleeve 105, an insertion side hole block 106, a locking component, and a wire component. The locking component includes a driving turntable 201, a side fastener 202, and a driving component. The wire component includes a sliding frame 301, a sliding sleeve frame 302, a wire wheel 303, and a limiting bolt 304. The driving component includes a connecting... The components include a plate 401, an arc-shaped cylinder 402, an arc-shaped plug 403, and a hydraulic regulating pump 404. The conductor assembly also includes an adjusting screw 305, a transmission bevel gear 306, a main rotating bevel gear 307, a main rotating shaft 308, a main rotating motor 309, and a plug-in component. The plug-in component includes a rotating shaft 501, an external toothed post 502, and a toothed mating sleeve 503. The plug-in component also includes a lateral shifting inner plate 504, a contact spring 505, and a limiting toothed sleeve 506. This solution addresses the common problems encountered in existing short fiber bundle uniform bundling devices. The assembly includes a fixed-installation guide assemblies, a filament bundle detection assembly, and a tension assembly. The relative positions of these components are fixed, and the guiding path and tension of the filament bundle are primarily determined by a fixed number of guide rings, guide rollers, and tension adjustment rods. However, in actual production, the total density of the filament bundle needs to be flexibly adjusted according to product specifications. This means that the number of short fiber bundles involved in bundling will frequently change. Existing bundling devices lack effective flexibility in adapting to different numbers of filament bundles in terms of guide path arrangement and tension adjustment range, typically only capable of optimizing designs for a fixed number of filament bundles. When the number of filament bundles changes, the original guide structure cannot be easily adjusted to accommodate the orderly guidance of the new number of filament bundles. Simultaneously, the tensioning mechanism struggles to apply uniform and individually adjustable tension to each filament bundle, leading to poor tension consistency between different filament bundles. This not only affects the uniformity and forming quality of the bundled filaments but also limits the flexibility of the production line and product changeover efficiency, making it difficult to meet the needs of flexible bundling processing of multiple varieties and small batches of short fiber filament bundles.

[0029] Furthermore, the main assembly mechanism 102 is mounted on the mounting base 101, and the fixed guide plate 103 is fixedly mounted on the mounting base 101. Twelve side hole sleeves 105 are fixedly mounted on the rear outer ring of both the fixed guide plate 103 and the splicing guide plate 104. Twelve insertion side hole blocks 106 are fixedly mounted on the front outer ring of the splicing guide plate 104. The insertion side hole blocks 106 on the splicing guide plate 104 are inserted one-to-one into the side hole sleeves 105 on the fixed guide plate 103. Both the fixed guide plate 103 and the splicing guide plate 104 are provided with locking components to lock and limit the insertion side hole blocks 106 and the side hole sleeves 105 after mating. Both the fixed guide plate 103 and the splicing guide plate 104 are provided with wire guides for guiding single-strand short fiber bundles.

[0030] In this embodiment, the main assembly mechanism 102 is an existing corresponding assembly device. The fixed guide plate 103 is provided at the feeding end of the main assembly mechanism 102. The fixed guide plate 103 and the splicing guide plate 104 are both fixedly installed with a corresponding number of side hole sleeves 105 and insertion side hole blocks 106.

[0031] In this technical solution, twelve side hole sleeves 105 and twelve insertion side hole blocks 106 are installed. These twelve side hole sleeves 105 and insertion side hole blocks 106 are evenly distributed around the outer ring of the fixed guide plate 103 and the splicing guide plate 104. This allows the splicing guide plate 104 to rotate 30 degrees, 60 degrees, 90 degrees, and 120 degrees when the insertion side hole blocks 106 are inserted into the corresponding side hole sleeves 105. This prevents the splicing guide plate 104 from intersecting with the front side hole sleeves during subsequent guidance of the designated short fiber bundles. The structure interferes with each other. The side hole sleeve 105 and the insertion side hole block 106 are mainly used to realize the stable insertion and cooperation between the two corresponding guide plates. Therefore, the number of side hole sleeves 105 and insertion side hole blocks 106 can be determined according to the actual situation. In this scheme, setting twelve means that the two corresponding guide plates can rotate in a unit of thirty degrees when they are installed. If six are set, it means that the two corresponding guide plates can rotate in a unit of sixty degrees when they are installed, and so on, so that the designers can design flexibly according to the actual situation.

[0032] In actual operation, the number of short fiber bundles to be processed is determined in advance according to the actual processing requirements. Then, a corresponding number of splicing guides 104 are installed according to the number of short fiber bundles. During installation, the splicing guides 104 are inserted into the side hole sleeves 105 on the fixed guide 103 through the corresponding insertion side hole blocks 106. Then, the locking member locks the insertion side hole blocks 106 and the side hole sleeves 105 after the insertion is completed. After the installation of one splicing guide 104 is completed, it is decided whether to install a second splicing guide 104 according to the actual situation. When installing subsequent splicing guides 104, the splicing guide 104 being installed is installed through the insertion side hole blocks. 106 is inserted into the side hole sleeve 105 of another splicing guide plate 104. Then, the inserted side hole block 106 and the side hole sleeve 105 are locked together by the locking member. After the corresponding number of splicing guide plates 104 are spliced, the corresponding number of short fiber bundles are guided by the corresponding number of splicing guide plates 104 in conjunction with the wire component and the wire component of the fixed guide plate 103. The guided short fiber bundles are bundled by the bundling body mechanism 102. This allows the guide of the corresponding fibers to be adjusted according to the number of short fiber bundles to be bundled according to actual needs by the provided components, so as to flexibly adapt to the bundling of short fiber bundles with different numbers of fibers.

[0033] Furthermore, both the fixed guide plate 103 and the splicing guide plate 104 are rotatably mounted with the drive turntable 201 on the side near the side hole sleeve 105; each drive turntable 201 is fixedly mounted with twelve side fasteners 202, the side fasteners 202 are arranged one-to-one with the side hole sleeve 105, and the side fasteners 202 are adapted to the side slots provided by the side hole sleeve 105 and the insertion side hole block 106; the driving component is connected to the drive turntable 201 and is used to drive the corresponding drive turntable 201 to rotate.

[0034] Furthermore, each of the drive turntables 201 is fixedly mounted with a connecting plate 401; the fixed guide plate 103 and the splicing guide plate 104 are both fixedly mounted with arc-shaped cylinders 402 on the side near the connecting plate 401; each arc-shaped cylinder 402 is provided with an arc-shaped plug 403, and the arc-shaped plug 403 is fixedly connected to the corresponding connecting plate 401; the fixed guide plate 103 and the splicing guide plate 104 are both fixedly mounted with a hydraulic regulating pump 404 on the side near the arc-shaped cylinder 402, and the hydraulic regulating pump 404 is connected to the corresponding arc-shaped cylinder 402 to control the actual hydraulic data inside the corresponding arc-shaped cylinder 402.

[0035] In this embodiment, the drive turntable 201 is equipped with twelve side fasteners 202 that cooperate with the corresponding side hole sleeves 105. Both the side hole sleeves 105 and the insertion side hole blocks 106 are provided with corresponding side slots. By rotating the drive turntable 201, the corresponding side fasteners 202 can lock the side hole sleeves 105 and the insertion side hole blocks 106 after they have been inserted, ensuring the stable installation between the splicing guide plate 104 and the fixed guide plate 103, as well as between the splicing guide plate 104 and the splicing guide plate 104.

[0036] The drive turntable 201 is fixed with a corresponding connecting plate 401, which is connected to the corresponding arc-shaped plug 403. The arc-shaped cylinder 402 and the arc-shaped plug 403 form a corresponding hydraulic cylinder structure. The hydraulic pressure inside the arc-shaped cylinder 402 is controlled by the hydraulic regulating pump 404, which in turn drives the corresponding arc-shaped plug 403 to slide on one side of the arc-shaped cylinder 402.

[0037] The arc-shaped cylinder 402 is provided with a corresponding arc-shaped inner guide structure to facilitate the arc-shaped plug 403 to move in an arc direction, thereby realizing the corresponding limit locking operation and lock release operation.

[0038] Furthermore, three sliding frames 301 are slidably mounted on both the fixed guide plate 103 and the splicing guide plate 104; each sliding frame 301 is fitted with a corresponding sliding sleeve frame 302; each sliding sleeve frame 302 is rotatably mounted with a guide wheel 303; the sliding sleeve frame 302 is connected to the corresponding sliding frame 301 by the limiting bolt 304.

[0039] Furthermore, each of the sliding frames 301 is equipped with a corresponding adjusting screw 305 for driving; each adjusting screw 305 is fixedly mounted with a transmission bevel gear 306, and three adjusting screws 305 are rotatably mounted on both the fixed guide plate 103 and the splicing guide plate 104, with the three adjusting screws 305 corresponding to and cooperating with the three sliding frames 301 one-to-one; the main rotating bevel gear 307 is rotatably mounted on both the fixed guide plate 103 and the splicing guide plate 104, and correspondingly mounted on the fixed guide plate 103 and the splicing guide plate 104 are... The three adjusting screws 305 are connected to the corresponding main rotating bevel gear 307 via the transmission bevel gear 306; the main rotating shaft 308 is rotatably mounted on the fixed guide plate 103 and is fixedly connected to the main rotating bevel gear 307 mounted on the fixed guide plate 103; the output shaft of the main rotating motor 309 is connected to the main rotating shaft 308, and the main rotating motor 309 is fixedly mounted on one side of the fixed guide plate 103; the plug-in component is connected to the splicing guide plate 104 to ensure the synchronous rotation of the two main rotating bevel gears 307.

[0040] Furthermore, the rotating shaft 501 is rotatably mounted on the splicing guide plate 104 and fixedly connected to the main rotating bevel gear 307 provided on the splicing guide plate 104; the external toothed column 502 is fixedly mounted on the side of the rotating shaft 501 near the fixed guide plate 103; the toothed groove mating sleeve 503 is fixedly mounted on the side of the rotating shaft 501 away from the fixed guide plate 103, and the toothed groove mating sleeve 503 is fixedly mounted on the side of the main rotating shaft 308 near the external toothed column 502, and the toothed groove mating sleeve 503 is provided with corresponding toothed grooves that match the external toothed column 502.

[0041] Furthermore, the lateral shift inner plate 504 is slidably installed inside the splicing guide plate 104; the two sides of the abutment spring 505 are respectively connected to the lateral shift inner plate 504 and the splicing guide plate 104; the limiting tooth sleeve 506 is fixedly installed on the side of the lateral shift inner plate 504 near the outer toothed post 502, and the limiting tooth sleeve 506 is provided with a fitting groove that matches the outer toothed post 502.

[0042] In this embodiment, the sliding frame 301 is provided with multiple threaded holes of different heights. The installation position of the sliding sleeve frame 302 can be adjusted by changing the mating position of the limiting bolt 304. The sliding sleeve frame 302 is provided with corresponding guide wheels 303 for guiding the specified short fiber bundles. In this solution, both the fixed guide plate 103 and the splicing guide plate 104 are provided with three sliding frames 301. Each sliding frame 301 is provided with a corresponding sliding sleeve frame 302 and guide wheels 303 for guiding the specified short fiber bundles.

[0043] The sliding frame 301 is driven by the adjusting screw 305, which is connected to the corresponding main rotating bevel gear 307 via the transmission bevel gear 306. The main rotating bevel gear 307 synchronously drives the three corresponding transmission bevel gears 306, ensuring the synchronous rotation of the three adjusting screws 305. This allows the three sliding frames 301 on the same fixed guide plate 103 or splicing guide plate 104 to maintain consistency during driving, ensuring that the guide axis of the multi-strand short fiber bundle remains unchanged when adjusting the guide position.

[0044] The main bevel gear 307 mounted on the fixed guide plate 103 and the splicing guide plate 104 is driven by the main rotating shaft 308 and the belt shaft 501, respectively. The main rotating shaft 308 is directly driven by the main rotating motor 309. The belt shaft 501 is connected to the main rotating shaft 308 through the cooperation of the external toothed post 502 and the toothed groove mating sleeve 503. When the splicing guide plate 104 and the fixed guide plate 103 are installed and spliced, the external toothed post 502 can be inserted and engaged with the toothed groove mating sleeve 503, so that when the main rotating shaft 308 is driven to rotate by the main rotating motor 309, the belt shaft 501 can rotate together with the main rotating shaft 308, realizing the synchronous adjustment of all the sliding frames 301.

[0045] The main purpose of driving the sliding frame 301 is to change the guide diameter during the multi-strand short fiber bundle guidance process, so as to adapt to different processing conditions. Moreover, the tension adjustment of the multi-strand short fiber bundle can also be completed by adjusting the guide diameter. When it is necessary to adjust the tension of the multi-strand short fiber bundle uniformly, the subsequent adjustment can be completed by driving all the sliding frames 301 uniformly.

[0046] The splicing guide plate 104 is also provided with a corresponding side-shifting inner plate 504 and a limiting toothed sleeve 506. When the outer toothed post 502 is inserted into the corresponding toothed groove mating sleeve 503, the toothed groove mating sleeve 503 will squeeze the limiting toothed sleeve 506, causing the limiting toothed sleeve 506 and the side-shifting inner plate 504 to move backward until the limiting toothed sleeve 506 disengages from the outer toothed post 502. After that, the outer toothed post 502 can rotate under the drive of the corresponding toothed groove mating sleeve 503. When the splicing guide plate 104 needs to be disassembled later, once the toothed groove... As the docking sleeve 503 moves backward, the side-shifting inner plate 504, under the action of the abutment spring 505, will drive the limiting toothed sleeve 506 to engage with the corresponding outer toothed post 502. After the splicing guide plate 104 is completely disassembled, the limiting toothed sleeve 506 will be fully fitted onto the outer toothed post 502 to limit the outer toothed post 502 and prevent it from rotating. This ensures that during subsequent engagement, the extension distance of the multiple sliding brackets 301 on the splicing guide plate 104 and the multiple sliding brackets 301 on the fixed guide plate 103 remains consistent.

[0047] It should be noted that, in order to facilitate the installation of multiple sets of splicing guide plates 104, the main rotating shaft 308 needs to be set with a fixed reset point. That is, during disassembly and installation, the main rotating shaft 308 needs to drive the corresponding toothed mating sleeve 503 to rotate to a specified angle. At this time, the toothed groove of the toothed mating sleeve 503 needs to be consistent with the fitting groove of the corresponding limiting toothed sleeve 506, so that when the splicing guide plate 104 is disassembled, the limiting toothed sleeve 506 can fit into the outer toothed connector 502. Moreover, during installation, the outer toothed connector 502 can also be quickly fitted into the outer toothed connector 502.

[0048] Preferably, the guide adjustment assembly provided by the present invention further includes a side guide frame 601, a lifting bracket 602, a screw lifting mechanism 603, and a tensioning component, wherein the tensioning component includes a wheel frame 701, a tensioning wheel 702, a pressure sensor 703, and a controller 704.

[0049] Furthermore, each sliding sleeve 302 is fixedly mounted with a side guide 601 on its side; each side guide 601 is slidably mounted with a lifting bracket 602; each side guide 601 is mounted with a screw lifting mechanism 603, which is connected to the corresponding lifting bracket 602 and is used to drive the corresponding lifting bracket 602 to move; the tensioning member is connected to the side guide 601 in a one-to-one correspondence and is used to tension the specified single strand short fiber bundle.

[0050] Furthermore, each of the lifting brackets 602 is equipped with a wheel frame 701; each of the wheel frames 701 is rotatably mounted with a tension wheel 702; each of the wheel frames 701 is equipped with a pressure sensor 703 on the side near the corresponding lifting bracket 602; each of the sliding sleeve brackets 302 is provided with a controller 704, which is electrically connected to the corresponding pressure sensor 703 and to the corresponding screw lifting mechanism 603, for controlling the operation of the specified screw lifting mechanism 603.

[0051] In this embodiment, each sliding sleeve 302 is equipped with an independent tension adjustment structure. The lifting bracket 602 is driven by the corresponding lead screw lifting mechanism 603, which mainly consists of a lead screw and a motor. The wheel frame 701 is connected to the side platform of the lifting bracket 602 via a top connecting platform. A pressure sensor 703 is provided on the top of the wheel frame 701. The tension wheel 702 on the wheel frame 701 guides the corresponding short fiber bundle. The corresponding short fiber bundle passes under the tension wheel 702 and is then led out through the corresponding guide wheel 303. Therefore, the tension force of the corresponding single short fiber bundle can be sensed by the pressure sensor 703. Then, the engagement height of the tension wheel 702 is adjusted by moving the lifting bracket 602, thereby changing the tension force of the corresponding single short fiber bundle.

[0052] The controller 704 is electrically connected to the corresponding pressure sensor 703 and the control element of the lead screw lifting mechanism 603, so that it can drive the lifting bracket 602 through the lead screw lifting mechanism 603 according to the pressure data sensed by the pressure sensor 703, thereby completing the flexible adjustment of the tension of the corresponding single short fiber bundle and ensuring the stability of the subsequent short fiber bundle bundling process.

[0053] Please see Figure 10 A method for uniformly bundling short fiber bundles, using the aforementioned short fiber bundle uniform bundling device, includes the following steps. S1: Determine the number of short fiber bundles to be processed in advance according to the actual processing requirements, and then install the corresponding number of splicing guide plates 104 according to the number of short fiber bundles. S2: When the splicing guide plate 104 is installed, it is inserted into the side hole sleeve 105 on the fixed guide plate 103 through the corresponding insertion side hole block 106. Then, the insertion side hole block 106 and the side hole sleeve 105 are locked and limited by the locking component. S3: After completing the installation of one splicing guide plate 104, decide whether to install the second splicing guide plate 104 based on the actual situation; S4: When installing the splicing guide plate 104, the splicing guide plate 104 being installed is inserted into the side hole sleeve 105 of another splicing guide plate 104 through the insertion side hole block 106. Then, the locking member locks and limits the insertion side hole block 106 and the side hole sleeve 105 after the insertion is completed. S5: After the splicing of the corresponding number of splicing guides 104 is completed, the corresponding number of short fiber bundles are guided by the corresponding number of splicing guides 104 in conjunction with the wire components set therein and the wire components of the fixed guide 103. S6: The corresponding short fiber bundles that are guided are bundled together by the bundling main body mechanism 102.
