Description

Technical Field

[0001] This invention relates to the field of basalt microrib production and preparation, and particularly to a mechanism for cutting continuous multi-rib basalt structures. Background Technology

[0002] In existing microfiber generation and preparation processes, it is often necessary to cut a large number of parallel microfiber bundles into several segments at high speed and stably according to a predetermined length for subsequent processing and packaging.

[0003] Most existing cutting devices lack sufficient lateral constraint and arrangement design for parallel multi-strand fiber bundles: single roller conveying or wide groove guiding cannot guarantee that each fiber bundle is in a stable and orderly arrangement before entering the cutting zone when the fiber bundle has a large number of strands, a small bundle diameter, or inconsistent spacing. This often results in fiber bundles intertwining, moving around, or clustering together. Such irregular arrangement leads to cutting position deviation, uneven cuts, inconsistent cutting lengths, and a decrease in yield.

[0004] Especially in high-speed fixed-length cutting of more than 200 fibers at a rate of 220 times per minute, it is difficult to achieve accurate feeding and stable clamping by relying solely on traditional cylinder clamping or a single constant-speed roller drive. Inadjustable clamping force or insufficient lateral constraint can lead to slippage, jumping, adhesion, or changes in the relative position of fiber bundles, directly affecting the cutting length accuracy and repeatability.

[0005] Traditional cutting methods often employ simple reciprocating linear or rotary cutting mechanisms. However, when dealing with micro-fiber bundles that possess a certain degree of rigidity or fragility, insufficient effective cutting force at the moment of blade entry can easily lead to localized fiber bundle breakage, burrs, or scattering of broken filaments. Conversely, simply increasing blade rigidity or sharpness to obtain greater cutting force increases the risk of brittle fracture or blade deformation. Furthermore, insufficient guidance control of the moving blade (existing lateral oscillation or nonlinear motion) will result in unstable cut quality, reduced tool life, and safety hazards.

[0006] Furthermore, industrial production requires equipment to be adaptable to different beam diameters, parallelisms, and materials, while also being easy for operators to observe, adjust, and maintain. Many existing devices lack adjustable feed clamping structures and effective feed guide combinations, making it difficult to quickly adjust on-site to adapt to changes in workpieces; the visibility of the housing, fault indications, and modular installation are also often overlooked, leading to time-consuming on-site troubleshooting and maintenance, and affecting production continuity. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to solve the problems in the prior art and provide a continuous multi-ribbed basalt structure rib cutting mechanism that can accurately cut a large number of ribs at high speed.

[0008] The technical solution of the present invention: The continuous multi-basalt structure micro-rib cutting mechanism of the present invention includes a conveying component and a cutting component. The conveying component includes an upper roller support component and a lower roller support component. The cutting component includes a fixed cutting blade component, a movable cutting blade component, and a cutting drive component that drives the movable cutting blade component to reciprocate up and down relative to the fixed cutting blade component. At least one guiding mechanism is provided in front of the cutting assembly. The guiding mechanism includes a guide partition and several guide grids evenly spaced on the guide partition. A micro-ribbed guide channel is formed between two adjacent guide grids, allowing the profile to pass through. The micro-ribbed guide channel prevents irregular arrangement of workpieces and improves the yield rate.

[0009] Furthermore, a mounting base plate is provided between the conveying assembly and the cutting assembly; A lower roller support assembly and an upper roller support assembly are fixedly installed on one side of the mounting base plate. A fixed cutter assembly and a moving cutter assembly are fixedly installed on the other side of the mounting base plate.

[0010] Furthermore, a linear guide rail is provided along the movement direction of the moving cutter assembly, and the moving cutter assembly is connected to the linear guide rail through a cutter guide block.

[0011] Furthermore, the cutting drive assembly includes a drive motor and a rotary support assembly connecting the drive motor and the moving cutter assembly; The rotating support assembly includes an eccentric wheel base and an eccentric wheel; the eccentricity of the eccentric wheel is the relative cutting blade opening and closing distance between the fixed cutting blade assembly and the moving cutting blade assembly.

[0012] Furthermore, the conveying assembly includes a feeding clamping roller assembly disposed at the front end of the upper roller support assembly and the lower roller support assembly; the feeding clamping roller assembly includes a set of roller assemblies with relatively adjustable distances.

[0013] Furthermore, a feed guide plate for supporting the fiber bundle to be cut is provided between the feed clamping roller assembly and the mounting base plate; guide partitions are provided on both sides of the feed guide plate.

[0014] Furthermore, the eccentric wheel base is fixedly connected to the moving cutter assembly via a cutter connecting seat, and the eccentric wheel is connected via a fixing pin.

[0015] Furthermore, the continuous multi-basalt structure micro-rib cutting mechanism also includes a support base for supporting and fixing the conveying component and the cutting component, and the support base is provided with a housing that encloses the conveying component and the cutting component.

[0016] Furthermore, the machine housing is provided with viewing windows on both sides for observing the feeding process.

[0017] Furthermore, the housing is equipped with indicator lights.

[0018] The beneficial effects of this invention compared to the prior art are as follows: 1. This invention provides at least one set of guiding mechanisms before the cutting assembly. These guiding mechanisms consist of guide partitions and guide grids evenly spaced on the guide partitions, creating micro-rib guiding channels between adjacent guide grids for the profile to pass through. This structural design directly aligns and orients multiple micro-ribs according to the channels before they enter the cutting zone, guiding them along a fixed path and into the cutting zone in an orderly manner. Combined with the upper and lower roller support components of the conveying assembly, which provide longitudinal support and propel the micro-ribs, it avoids irregular movement or cross-linking of the workpiece before cutting. Therefore, this invention, through the clearly defined structural means of the micro-rib guiding channels formed by guide partitions and guide grids, directly improves the consistency of workpiece arrangement, thereby increasing the yield rate.

[0019] 2. Compared to existing designs, the cutting drive assembly in this invention includes a drive motor and a rotary support assembly. The rotary support assembly comprises an eccentric wheel base and an eccentric wheel, with the eccentricity limited to the relative opening and closing distance between the fixed and moving cutter assemblies. This eccentric mechanism effectively converts the rotational motion of the drive motor into the reciprocating motion of the moving cutter assembly, and generates a downward inertial component at the beginning and end of the motion. Essentially, it converts part of the rotational inertia into cutting impact force, increasing the effective cutting force of the tool during instantaneous entry, which is beneficial for high-speed and clean cutting of micro-rib bundles with a certain degree of rigidity. Furthermore, a linear guide rail is provided along the movement direction of the moving cutter assembly and connected by a cutter guide block. This guiding mechanism ensures the linear and controlled movement of the moving cutter, reduces lateral vibration, and improves the consistency of tool contact. Therefore, through the synergistic technology of the eccentric and rotary support structure and the linear guide, this invention enhances the instantaneous cutting power and ensures the linearity and stability of the tool movement, thereby achieving reliable and non-fragile cutting quality even under high-volume, high-frequency cutting requirements.

[0020] 3. In this invention, the feed clamping roller assembly at the conveying end is a "set of roller assemblies with adjustable distances," and a feed guide plate is provided between the feed clamping roller assembly and the mounting base plate, with guide partitions on both sides of the feed guide plate. This combination of adjustable clamping rollers, feed guide plate, and guide partitions, through adjustable clamping force and lateral constraint, can adapt to fiber bundles with different cross-sections or diameters, and maintain the stable force and position of the bundles during high-volume and high-speed conveying, significantly reducing slippage, jumping, or clustering, thereby improving the system's throughput and feeding stability. Furthermore, the arrangement of the mounting base plate, support base, casing, and its viewing windows and indicator lights facilitates real-time observation of the feeding status by operators, allowing for quick identification of abnormalities and maintenance or adjustment, while also facilitating the installation, debugging, and daily maintenance of the entire machine. Therefore, compared to existing designs, this invention achieves stable and high-capacity processing of high-parallel-count fiber bundles through the adjustable clamping and guiding combination, and improves on-site operability and maintenance convenience through reasonable installation and human-machine interface configuration.

Detailed Implementation

[0022] To enhance understanding of the present invention, we will now describe it in further detail with reference to the accompanying drawings. These embodiments are for illustrative purposes only and do not constitute a limitation on the scope of protection of the present invention.

[0023] Example 1 like Figure 1-3 As shown, the continuous multi-ribbed basalt structure micro-rib cutting mechanism of this embodiment includes: The conveying assembly mainly consists of an upper roller support assembly 21 and a lower roller support assembly 22, which are used to provide longitudinal support and propel multiple micro-ribs. The cutting assembly includes a fixed cutter assembly 11, a movable cutter assembly 12, and a cutting drive assembly 10 for driving the movable cutter assembly 12 to reciprocate up and down relative to the fixed cutter assembly 11. At least one set of guide mechanisms 5 is provided in front of the cutting assembly. The guide mechanism consists of a guide partition 51 and several guide grids 52 that are evenly and equidistantly arranged on the guide partition 51. A micro-rib guide channel 50 is formed between two adjacent guide grids 52 for the micro-ribs to pass through.

[0024] Preferably, the guide grid 52 consists of several parallel vertical bars arranged at equal intervals, forming narrow, elongated channels 50 with consistent shapes between adjacent grids. The channel spacing is determined based on the total cross-section and single bundle diameter of the microrib bundles, ensuring that the microribs are laterally positioned and arranged before entering the cutting area.

[0025] The upper roller support assembly 21 and the lower roller support assembly 22 are positioned opposite each other. The rollers are made of a surface material suitable for the friction coefficient of basalt microribs to achieve stable traction without damaging the surface of the microribs. The axial arrangement of the upper and lower rollers corresponds to the channel formed by the guide grid 52, ensuring that the microribs in each channel maintain linear movement along the guide channel under the clamping and driving of the rollers.

[0026] The fixed cutter assembly 11 and the moving cutter assembly 12 are arranged opposite to each other. The moving cutter assembly 12 is driven by the cutting drive assembly 10 to perform reciprocating motion to achieve shearing. More preferably, the blade material, blade shape, and cutting edge angle can be selected according to the brittleness of basalt fibers and the required cutting quality, for example, high-hardness alloy or coated blades can be selected.

[0027] During operation, multiple parallel microribs are guided through the microrib guide channel 50 of the guide mechanism 5; the upper roller support assembly 21 and the lower roller support assembly 22 provide longitudinal support and propel the microribs, so that the microribs reach the cutting gap in a stable state; the cutting drive assembly 10 drives the moving cutter assembly 12 to move up and down relative to the fixed cutter assembly 11 to complete the cutting, and the cut microribs are collected and stored.

[0028] Example 2 This embodiment, based on embodiment 1, further includes: The mounting base plate 3 is located between the conveying assembly and the cutting assembly and serves as a common mounting platform for both. A lower roller support assembly 22 is fixedly installed on one side of the mounting base plate, and an upper roller support assembly 21 is fixedly installed above the lower roller support assembly 22. A fixed cutter assembly 11 and a moving cutter assembly 12 are fixedly installed on the other side of the mounting base plate.

[0029] Preferably, a linear guide rail 40 is provided along the movement direction of the moving cutter assembly 12, and the moving cutter assembly 12 is connected to the linear guide rail 40 through the cutter guide block 121 to achieve precise linear guidance of the moving cutter.

[0030] The cutting drive assembly 10 specifically includes a drive motor 101 and a rotary support assembly 102 that transmits the motion of the drive motor 101 to the moving cutter assembly 12. The rotary support assembly 102 includes an eccentric wheel base 1020 and an eccentric wheel 1021. The eccentricity of the eccentric wheel 1021 is set as the relative cutter opening and closing distance between the fixed cutter assembly 11 and the moving cutter assembly 12. The eccentric wheel base 1020 is fixedly connected to the moving cutter assembly 12 via a cutter connecting seat 1023 and to the eccentric wheel 1021 via a fixing pin 1024 to ensure transmission rigidity and reliable positioning.

[0031] More preferably, the surface of the mounting base plate 3 may be provided with grooves or mounting holes to facilitate the fixing of the upper and lower roller support assemblies 21 and 22, the linear guide rail 40, and the fixed and moving blade assemblies 11 and 12. The thickness and rigidity of the mounting base plate should be able to withstand the cutting inertial load and the feeding torque.

[0032] The linear guide can be a roller / ball linear guide, and the cutter guide block 121 adopts a slider structure with extremely small mating clearance and is provided with a lubrication channel to reduce friction and wear.

[0033] The drive unit 101 can be a servo motor or a high-response servo driver. For example... Figure 4 As shown, the eccentricity between the eccentric wheel 1021 and the eccentric wheel base 1020 is precisely equal to the predetermined blade opening and closing distance. When the eccentric wheel rotates, it transmits the reciprocating motion to the moving cutter assembly 12 through the tool connecting seat 1023. The eccentric wheel is fastened to the rotating shaft by a fixing pin 1024 or a key lock to ensure the safety and reliability of power transmission.

[0034] The blades of the fixed cutter assembly 11 and the moving cutter assembly 12 can be designed in a modular form with replaceable blades, and the tool connector 1023 can realize quick-release replacement of the tool, which is convenient for maintenance.

[0035] More preferably, the drive motor 101 adopts servo control, which can set the reciprocating frequency, stroke, and phase of the moving blade to achieve electronic synchronization with the conveying speed, thereby ensuring the accuracy of fixed-length cutting. Driven by the servo motor, the eccentric mechanism rotates at a set angular velocity, causing the moving blade assembly 12 to perform a controlled up-and-down reciprocating stroke. The eccentric structure generates an additional axial inertial force at the moment of entry, thereby amplifying the instantaneous cutting force, which is beneficial for cutting high-rigidity micro-rib bundles without solely relying on blade sharpness. The linear guide rail 40 and the blade guide block 121 maintain the linear movement of the moving blade, suppressing lateral sway and vibration, ensuring consistent blade positioning each time it enters the blade, thereby reducing the probability of fiber breakage and extending blade life.

[0036] Example 3 Based on Example 2, combined with Figure 5 and 6 This embodiment further includes: The front end of the conveying assembly is provided with a feeding clamping roller assembly 53, which includes a set of roller assemblies with adjustable distance for adjusting clamping of the micro-rib bundles at the feeding end; a feeding guide plate 61 is provided between the feeding clamping roller assembly 53 and the mounting base plate 3, and guide partitions 51 are provided on both sides of the feeding guide plate 61, which cooperate with the guide grid 52 to form a continuous guiding path; The device is also provided with a support base 1 for supporting and fixing the conveying component and the cutting component. The support base 1 is provided with a housing 13 that wraps the conveying component and the cutting component. The housing 13 has viewing windows 14 on both sides for observing the feeding. The housing 13 is provided with indicator lights 15 for indicating the operating status or fault. Regarding the connection between the rotary support assembly 102 and the moving cutter assembly 12, the eccentric wheel base 1020 is fixedly connected to the moving cutter assembly 12 through the cutter connecting seat 1023, and connected to the eccentric wheel 1021 through the fixing pin 1024 to ensure rigid transmission.

[0037] More preferably, the feed clamping roller assembly 53 consists of several pairs of rollers. The relative distance between the roller pairs can be adjusted along the axial direction using a screw or cylinder mechanism, allowing for adjustment of clamping force from light to large for micro-ribs with different total cross-sections or numbers of strands. The roller surface material can be natural rubber or PU to balance gripping force with no damage to the fibers. To ensure feeding stability for high-speed fixed-length cutting, the clamping force can be adjusted using techniques such as spring preload, manual screw, or cylinder control, and force or position sensors can be added for closed-loop adjustment.

[0038] The housing 13 covers the critical movement and cutting tool areas to improve safety, while impact-resistant transparent windows 14 are provided on both sides as viewing windows, allowing operators to observe the feeding and cutting process in real time. Indicator lights 15 are installed on the housing to display the equipment status, such as green: working, yellow: standby / warning, red: fault, and can be linked to the protection circuit to automatically shut down the machine in case of abnormality.

[0039] The above specific embodiments are only for illustrating the technical concept and structural features of the present invention, and are intended to enable those skilled in the art to implement them. However, the above content does not limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit and essence of the present invention should fall within the scope of protection of the present invention.
