Description

Technical Field

[0001] This invention relates to textile trimming and processing, specifically to an intelligent ultra-wide precision shearing machine. Background Technology

[0002] In recent years, significant changes have occurred in the textile industry, from raw materials to finishing processes. In particular, the increasingly fierce competition faced by standard-sized textiles has impacted the healthy development of enterprises and the industry as a whole. The international advocacy for low-carbon production in recent years has placed increasingly higher demands on clean and energy-efficient manufacturing. The current situation of low-price competition and unstable orders has constrained the healthy development of enterprises, making refined production process control and intelligent, reduced-staff production imperative.

[0003] For the finishing industry, especially the shearing process, a large amount of polluted waste gas, waste wool, and dust particles are generated during the production process, causing pollution and waste of raw materials. More advanced management concepts and construction processes are needed. In particular, the shearing process is a material-consuming process, and ensuring the minimum shearing amount is a long-term and urgent requirement. However, to achieve this well, a highly stable and high-precision automated equipment is needed.

[0004] For shearing machines, especially precision shearing machines, the shearing amount is generally 0.5-1.5mm. However, for textiles with a total pile height of 2.5-3.5mm, the sheared portion already accounts for more than 15% of the fabric raw material. Moreover, the sheared portion directly becomes waste that is difficult to recycle and also causes environmental pollution, requiring professional methods for harmless treatment. In addition, each shearing production line has a daily capacity of more than 15,000 meters. If the shearing amount in the process could be reasonably reduced, even if the raw material loss is reduced by 50%, the social and economic benefits would be significant. However, due to structural and precision limitations, existing technologies are difficult to achieve this well.

[0005] The shearing amount of existing shearing machines is mainly determined by the effect after shearing, and the spacing is manually adjusted. In order to facilitate adjustment and ensure the quality of finished products, the shearing amount is generally increased to reduce the frequency of operation in the production process, so as to avoid human error causing defective and waste products. This is also why existing technologies generally have a large material loss.

[0006] A good shearing effect depends on the complete unfolding of the fiber filaments upon entering the shearing zone, and the removal of the tips with uniform straightness. This is why combing and ironing processes are necessary before shearing. However, the wool fibers undergo varying degrees of deformation during the weaving process. The fibers themselves are soft, and even after brushing and ironing, some shape and length differences remain. Therefore, strong suction is needed to straighten the fibers before trimming. Thus, the suction strength and volume determine the final shearing effect. Existing shearing suction devices mainly have two types: upper and lower air outlets, corresponding to different shearing amounts. Furthermore, the multiple suction pipes, due to spatial layout and other factors, result in varying suction resistance, leading to significant deviations in suction effect. Waste wool generated after shearing easily adheres to the inner cavity of the air hood and clumps up, falling onto the surface of the fabric to be sheared, further exacerbating the difficulty of shearing.

[0007] The degree of fiber filament extension entering the shearing zone and the angle between the fiber and the fixed flat blade during shearing are also key factors that directly affect the straightening of the fiber filaments by the suction system. However, existing technologies generally use a fixed shearing blade structure. When the pile height (the fiber length formed after shearing, which is also the finished fiber length) is adjusted, the shearing angle of the fiber filaments changes significantly. That is, what was originally a perpendicular shearing to the fiber filament direction becomes a slanted shearing. After shearing, a large slope surface is generated at the pile tip, which affects the brightness of the pile surface. In some cases, due to the excessively large shearing angle, the pile may not be cut properly or may stick together after shearing, requiring secondary shearing and resulting in production waste.

[0008] During the weaving process, due to space limitations in the equipment, the greige fabric is generally of a specific length. In the subsequent wet and dry finishing processes, it is sewn and spliced ​​as needed to form longer lengths for continuous production. Because the greige fabric is woven to a fixed length and then sewn, a large number of seams (seam ends) are generated. During finishing, especially dry finishing, the finishing device needs to avoid these seam ends. Current technologies generally use photoelectric detection or gravity-based micro-motion amplification, which are easily affected by factors such as dust, electromagnetic fields, and mechanical vibrations, leading to signal errors, malfunctions, or even production accidents. Therefore, the existing automatic seam end avoidance function is insufficient and cannot be stably promoted. Seam end avoidance still relies on manual operation, which poses a significant obstacle to achieving intelligent production in the future and is a problem that must be overcome at this stage.

[0009] During normal operation of shearing equipment, the circular blade assembly and the flat blade are in sliding friction contact, requiring good lubrication. Therefore, an oil felt lubrication system is installed. Current technology involves manual, periodic lubrication, which causes on-site contamination each time. Furthermore, the effectiveness of manual lubrication relies on experience and is therefore somewhat uncertain. Summary of the Invention

[0010] (a) Technical problems to be solved

[0011] To address the shortcomings of existing technologies, this invention provides an intelligent ultra-wide precision hair shearing machine that effectively utilizes the high weather resistance and anti-interference characteristics of lasers to achieve accurate and long-term stable non-contact measurement. The comprehensive application of photoelectric signal transmission technology solves the adverse effects of transmission process and distance, resulting in a significant improvement in signal transmission accuracy.

[0012] The effective application of precision electro-optical actuator measurement and control technology has effectively solved the problems of positioning accuracy and high response of automatic execution, avoided the reaction error of manual operation, realized autonomous seeking action, and effectively reduced unnecessary loss of production raw materials.

[0013] The effective application of alternating laminar flow suction dust removal technology, based on the airflow characteristics generated by the rotation of equipment components and the movement characteristics of entrained waste, optimizes the use of fluid dynamics technology to meet the suction needs of the shearing area and the centralized suction and conveying of waste wool after shearing with lower suction energy consumption. It solves the problems of unstable local area performance of the shearing suction system and easy dirt accumulation on the inner walls of each duct cavity.

[0014] The effective application of flexible variable cross-section technology in air ducts effectively solves the problem that the flow error of the branch pipes in the air suction system cannot be adjusted independently, and avoids problems such as dirt and blockage and difficulty in cleaning caused by the use of valve groups in the branch pipes of the air suction system.

[0015] By adopting a modular design scheme, the problems of insufficient rigidity and difficulty in forming ultra-long sheet metal components were solved.

[0016] The intelligent automatic timed lubrication system solves the problems of on-site contamination and uneven lubrication, effectively improving the stability of the shearing process and extending the service life of the shearing components.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example

[0049] like Figure 1-9As shown, one embodiment of the present invention proposes an intelligent ultra-wide precision shearing machine, comprising a machine frame 1, a fabric feeding and correction mechanism 2, a fabric feeding and tightening mechanism 3, a fabric feeding and spreading mechanism 4, a seam detection mechanism 5, a traction mechanism 6, an in-machine spreading mechanism 7, a shearing mechanism 8, a suction system 9, a fabric output and spreading mechanism 10, a crane mechanism 11, and a metal detector 12. This intelligent ultra-wide precision shearing design is mainly used for key processing steps in the finishing of textile products. By quantitatively trimming the fiber tips of textiles, it achieves... To achieve a uniform and even finish, this technology is primarily used in the carpet and large-format decorative pile industries for ultra-wide textiles. Its main components include a uniform pressure powerful suction device, an intelligent precision shearing device, and an automatic non-contact online detection and intelligent control system for seam ends. The shearing process utilizes a rotating circular blade with spiral blades on its surface and a fixed flat blade to create a shearing zone, trimming the tips of the pile. The finished pile surface has a uniform height of the tips, or a style where the highest points of the tips are even. Textiles, due to material specifications and process requirements during the weaving process... All of these fabrics are woven from bundles or threads composed of multiple fibers, and then processed through untwisting, combing, ironing, and finishing techniques to create a dense structure of single fibers on the fabric surface. During this process, the original single fibers are twisted or wrapped together into bundles. After untwisting and ironing, a certain number of single fibers grow out, making the entire surface appear messy and affecting its shine and overall style. Proper trimming through a shearing process is necessary to achieve the desired effect. The shearing process involves removing fibers at their highest point, i.e., fixed-height trimming. If a large number of bent single fibers remain during this process, they will straighten and grow outwards after trimming, affecting the trimming effect. To ensure that the fibers enter the shearing zone straight, a powerful suction system with a specific structure is used to straighten the fibers indiscriminately, effectively guaranteeing the desired result. To further enhance the suction effect, a support mechanism is installed on the back of the fabric within the suction zone, allowing the fabric to form sharp protrusions that enter the suction zone. The sharp corners allow the fibers on the front of the fabric to be fully separated, creating a structure that facilitates airflow and further enhancing the straightening effect.This invention addresses the production conditions of a shearing machine by employing a control scheme that combines automatic online measurement, electric precision adjustment of clearances, and manual stage error compensation. Combined with advanced process data processing and logic control execution, the machine achieves higher precision and a higher level of intelligence. At one end of the machine frame 1, from top to bottom, are sequentially arranged a fabric feeding and correction mechanism 2, a fabric feeding and tightening mechanism 3, and a fabric feeding and spreading mechanism 4. These mechanisms work together. A metal detector 12 is installed on the machine frame 1 between the fabric feeding and tightening mechanisms 3 and 4. A crane mechanism 11 is installed on the top of the crossbeam of the machine frame 1. A fabric outlet swing arm is installed at the other end of the machine frame 1. The fabric feeding and spreading mechanism 10, along with the fabric feeding and spreading mechanism 4, has a seam detection mechanism 5 mounted on the wall panel below the main frame 1. Below the seam detection mechanism 5, a traction mechanism 6 is mounted on the wall panel, working in conjunction with the fabric feeding and spreading mechanism 4. An internal fabric spreading mechanism 7 is mounted on the wall panel to one side of the traction mechanism 6. Above the internal fabric spreading mechanism 7, a shearing mechanism 8 and a suction system 9 are mounted on the wall panel. Through a combined structure and adaptation to the characteristics of the fabric to be processed, utilizing kinematics and fluid dynamics technologies, the entire machine is configured with functional work areas and specific structures according to the digital requirements of the process flow parameters. Through simulation verification, accurate control is achieved, efficiency is improved, and on-site construction, maintenance, and safe and efficient production are facilitated. Precision manufacturing is employed. The system utilizes a precision lead screw and servo drive to achieve high-response motion and precise digital positioning. Laser ranging technology is employed for accurate measurement of the shearing gap and height. Two independently set height-raising mechanisms enable rapid and accurate height positioning. A precision lead screw with an indexable joint allows for on-demand rotational fine-tuning and positioning compensation of the support knife, promptly compensating for changes in the fiber shearing angle caused by height adjustments, thus achieving autonomous and precise height adjustment. It can also perform large-stroke rotation of the support knife to achieve seam head avoidance. Laser ranging technology detects the seam head position, and a counting device on the traction power reducer simulates seam head position changes, achieving precise and stable seam head signal detection and ensuring rapid and accurate seam head avoidance. Currently, the time spent on seam avoidance is effectively reduced, preventing fabric waste and ensuring that unprocessed fabric is discarded during the rolling process. The combined suction hood structure avoids the problem of insufficient width in the forming equipment and facilitates other processing steps. The segmented structure also effectively ensures the dimensional accuracy of each cross-section of the cavity. The multi-point continuously distributed ventilation ducts are connected by flexible hoses, each equipped with a hose reducer, enabling fine-tuning compensation of the flexible hose cross-section for different sections. This reduces processing difficulty while improving the adaptability of the system's zoning function. A matching air distribution chamber component facilitates centralized airflow from each branch duct. The air distribution chamber has a cleaning port for regular cleaning, further ensuring system cleanliness and safety.The system features an adjustable-gap arc-shaped air regulating plate 9-12 behind the hood, which can be finely adjusted to match the amount of waste lint generated during shearing and the suction pressure under different working conditions. Utilizing laminar flow mechanisms and localized airflow technology, it prevents lint from directly contacting the inner cavity of the hood, thus avoiding adhesion and adsorption, further improving dust removal efficiency and achieving energy-saving dust removal and convenient maintenance. An automatic oiling device controlled by a PLC controls the oiling cycle period and oiling volume. The oiling pipe of the oiling device has evenly distributed oil inlets and is fixed to the lubrication felt frame via a hinge, allowing for manual lateral displacement of the oiling pipe as needed, further increasing the uniformity of oiling. An adjustable arc-shaped wind baffle with a wind helix cross-section shape conforming to fluid kinematics principles prevents clean airflow containing waste lint and other contaminants from directly impacting the working inner cavity of the suction hood, effectively preventing contamination of the hood's inner wall. The clean, fresh air laminar flow counteracts the waste lint and contaminant particles generated during the shearing process, increasing their upward buoyancy and accelerating their removal.

[0050] like Figure 2 As shown, in some embodiments, two symmetrically arranged conical air distribution chambers 9-02 are connected to a fixed crossbeam 9-03 by bolts to form the air distribution chambers of the whole machine; the air outlet of each air distribution chamber 9-02 faces outward and is fixed with a special reducing duct connector 9-01 by bolts for easy connection with an external dust collector fan; each air distribution chamber 9-02 has a cleaning window 9-04 on its inner side for easy periodic cleaning; the support legs provided under the air distribution chamber 9-02 are fixed to the fixed crossbeam to form the air intake and distribution channel of the whole machine; each air distribution chamber 9-02 has an air inlet connector with an angle on its lower side and is connected to the air outlet of the symmetrically arranged shearing suction hoods 9-07 by suction hoses 9-05, and is fastened with hose clamps; the left and right shearing suction hoods 9-07 are fixed to the flat blade holder by bolts, and the inner side plates of the left and right shearing suction hoods 9-07 are respectively equipped with... Bolted connections form a complete shearing suction hood 9-07 covering the entire shearing circular blade assembly. Each shearing suction hood 9-07 has an adjustable arc-shaped baffle 9-12 on its rear vertical section, connected via a fixed handle. The lower end of the arc-shaped baffle 9-12 forms an adjustable air inlet gap with the flat blade holder, creating a narrow airflow during operation to prevent lint and other dirt from reaching and adhering to the inner wall of the shearing suction hood 9-07. Suction cones with different air inlets are located at the center of the rear side of the shearing suction hood 9-07, connected to the air inlet of the air distribution chamber 9-02 via flexible hoses. The sucked-up lint is collected in the air distribution chamber and discharged. Side baffles 9-06 are located on the outermost two sides of the shearing suction hood 9-07, further strengthening the seal between the hood and the shearing mechanism, solving the problem of leakage at the outer ends of the hood during lint suction. Figure 4 This is a schematic diagram of the gas flow under the shroud.

[0051] like Figure 3As shown, in some embodiments, the shearing suction hood 9-07 is a symmetrically manufactured part, which is then assembled into a complete hood during fixing. The hood is formed by component welding. The reinforcing rib 9-7-01, the middle support leg 9-7-02, the fixed chamber 9-7-07, and the outer support leg 9-7-09 are welded together according to their dimensions. The fixed chamber 9-7-07 has a ventilation opening on its rear near-planar contour plate. The outer conical tube 9-7-08 and the middle conical tube 9-7-03 are welded to the outside of the opening from the outside to the middle, respectively. The outer openings of each conical tube are welded with round air ducts 9-7-05. The outer side of the curved part of the cavity of the fixed chamber 9-7-07 is welded with an arc plate 9-7-06 to strengthen the rigidity of the cavity, which finally constitutes the fixed part of the shearing suction hood 9-07. The movable middle side plate 9-7-13, the movable outer side plate 9-7-15, and the movable chamber 9-7 are also present. -14. The reinforcing cross brace 9-7-12 is welded to form the movable part of the shearing suction hood 9-07 according to the dimensions. A rotating lever arm 9-7-11 is welded to the outer side of the middle of the reinforcing cross brace 9-7-12 to form a rotation force point. The movable part of the shearing suction hood 9-07 is welded to the fixed part of the shearing suction hood 9-07 through a welded hinge 9-7-04 to form a complete single shearing suction hood 9-07. To ensure the safe rotation position of the movable part of the shearing suction hood 9-07, limit blocks 9-7-10 are welded to the inner cavity of each leg of the fixed part of the shearing suction hood 9-07. Adjustment bolts are provided on the movable part of the shearing suction hood 9-07 corresponding to the limit blocks 9-7-10, which realizes the rapid spatial position adjustment and safety restriction of the movable part of the shearing suction hood 9-07, and ensures the safe movement of the shearing suction hood 9-07.

[0052] like Figure 3As shown, in some embodiments, felt frames 9-08 are respectively installed on the exterior of the movable part on the front side of the shearing suction hood 9-07. The felt frames 9-08 have a round shaft head on the middle side, which is perforated and installed on the middle side plate of the shearing suction hood 9-07. The other end has a stepped shaft, which is fitted into the upward-facing opening of the outer side plate of the shearing suction hood 9-07. A safety lock plate 9-14 is bolted to the outer side plate of the shearing suction hood 9-07 to limit its movement. The outer ends of the felt frames 9-08 on the middle side are respectively bolted to connecting plates 9-15. The two connecting plates... The plate is bolted in place to prevent the central round shaft from falling out of the hole in the middle side plate of the shearing suction hood 9-07 due to lateral movement of the felt frame 9-08, thus further improving equipment safety. Lubricating felt 9-09 for lubricating the round blades is installed on the lower extension plate of the felt frame 9-08, and is secured by evenly distributed bolts connected to the felt pressure plate 9-10. A lubrication device 9-11 for periodically lubricating the lubricating felt 9-09 consists of multiple lubrication connecting plates 9-13 bolted to the outer side of the upper pipe section of the felt frame 9-08. The sliding connecting plate 9-13 has a long hole and a round hole at both ends for fixing, which facilitates the adjustment of the refueling pipe of the refueling device in terms of vertical and horizontal position as needed; a swing cylinder joint 9-16 is hinged to the rotating arm of the movable part of the shearing suction hood 9-07, and the cylinder rod of the swing cylinder 9-17 is fastened to the swing cylinder joint 9-16. The base is pin-connected to two cylinder seat plates 9-19, which are respectively bolted to the middle support leg of the shearing suction hood 9-07. The two cylinder seat plates 9-19 are connected to the shearing suction hood 9-07. The two middle support legs 9-7-02 are equipped with adjusting bolts 9-18 for safe and secure positioning; when the swing cylinder 9-17 is activated, it drives the moving part of the shearing suction hood 9-07 and the assembled components on it to rotate upward, realizing individual or linkage opening and closing as needed; the shearing suction hood 9-07 is equipped with a conical air duct, realizing wide-range uniform pressure suction, and the optimized design of the equivalent cross-sectional area of ​​the air inlet and outlet gaps effectively reduces the process wind resistance, ensuring the good condition of the wool entering the shearing zone, and providing a good guarantee for efficient shearing.

[0053] like Figure 5As shown, in some embodiments, bearing seats 5-01 are concentrically mounted on both ends of the support shaft 5-02 of the seam detection device and fixed to the two side wall plates with bolts. Two connecting plates 5-03 are coaxially fitted onto the tube body of the support shaft 5-02 with holes drilled at one end. A square support 5-04 is installed on the inner side in the middle, and its two ends are respectively bolted to the connecting plate 5-03. After alignment, it is positioned by set screws. Self-aligning bearings 5-06 are installed in the holes at both ends of the detection roller 5-05 and positioned by a hole retaining ring 5-07. One end of the detection roller core shaft 5-08 is concentrically mounted in the inner hole of the self-aligning bearing 5-06, and the other end is fixed to the connecting plate 5-03 with bolts. One end of the detection connecting plate 5-09 is fitted onto the support shaft near the wall plate and positioned by set screws. One end of the detection stop frame 5-10 is fixed to the detection plate with bolts. On the connecting plate 5-09, a detection stop 5-14 is installed at the other end, forming a rigid body that can rotate as a whole along the bearing seat 5-01; the detector 5-13 is fixed to the detector support 5-12 with screws, and the detector cover 5-11 fixed to the detector support 5-12 with screws provides light protection. Since the emitter and receiver of the laser detector are on the same side of the same instrument, isolating the natural light of a certain wavelength in the working environment can significantly increase the instrument's resistance to ambient light interference. The advantages of the laser beam, such as strong resistance to electromagnetic interference, strong penetration, and high feedback accuracy, are effectively utilized, improving the reliability of the seam detection system while also increasing the accuracy by orders of magnitude; the detection stop 5-10 adopts a multi-joint locking fixing method, which allows for convenient multi-dimensional adjustment of the spatial position and angle.

[0054] like Figure 6 As shown, in some embodiments, existing seam detection technologies mostly use capacitive and inductive instruments, requiring numerical calculation and conversion of displacement values ​​for comparison, i.e., real-time detection and comparative calculation. When detecting changes in electrical signal values ​​caused by positional changes, in most cases, the changes in electrical signal values ​​caused by positional changes are close to those caused by environmental factors. Therefore, signal amplification and re-acquisition are the only methods available. However, signal fluctuations caused by mechanical micro-vibrations cannot be eliminated. Thus, existing technologies can only be used in situations where the magnitude of the change is sufficient to cover errors caused by environmental conditions. The laser ranging technology of this invention uses a control method that switches the signal on / off after the detection distance exceeds the limit, directly shielding signal fluctuations within the range. The limit position value is directly set and modified by the PLC based on the fabric characteristic parameter values ​​or codes input into the production system, calling data from the equipment database, or manually set and modified via the touchscreen, and then stored. This is an intelligent process of automatic matching of process parameters, ensuring safety and reliability.

[0055] like Figure 7As shown, in some embodiments, the shearing mechanism consists of a circular blade assembly 8-01, a circular blade support assembly 8-02, a circular blade assembly 8-03, a circular blade transmission assembly 8-04, a flat blade holder assembly 8-05, a shearing blade assembly 8-06, and a hair height adjustment assembly 8-07.

[0056] like Figure 8 As shown, in some embodiments, the existing technology of the shearing blade assembly falls into two main categories. The first is a combination of an eccentric block and a flange ring. Due to structural limitations, the external dimensions are restricted, resulting in a short generatrix at the working contact surface, which is prone to wear and failure, and is also susceptible to overheating and jamming during operation. The second is a combination of a double connecting rod and an eccentric block, where the kinematic pair uses sliding friction. This type of technology requires extremely high precision and suffers from uneven wear, leading to excessive wear and failure of the connecting rod mechanism. This type of structure is gradually being phased out. Existing technologies are currently mainly used in light-load, low-speed applications, and their shortcomings have limited the expansion of shearing equipment. This invention, based on the current state of the technology, comprehensively solves the existing problems in terms of rigidity, stability, and high load capacity; the structure is as follows. Figure 8 As shown, the tool sleeve 8-1-02 is concentrically mounted on the shaft at one end of the round cutter via two deep groove ball bearings 8-1-01. The two deep groove ball bearings 8-1-01 and the tool sleeve 8-1-02 are respectively fixed to the outer side of the tool sleeve using hollow elastic retaining rings, and are locked to the shaft end of the round cutter using bolts and shaft end retaining rings, forming a component that can rotate with the round cutter assembly. Two tool pull plates 8-1-10 are respectively fixed to the outer side of the tool sleeve 8-1-02 by bolts, and have symmetrical flat... On the surface, the inner limiting plate 8-1-03 and the outer limiting plate 8-1-09 are fixed with bolts respectively, forming a cavity between the two plates; the cutter shaft 8-1-06, mounted on the reducer, passes through the anti-rotation elongated hole on the adjacent cutter pull plate 8-1-10 into the cavity, and the eccentric sleeve 8-1-04 and the cylindrical surface bearing 8-1-05 are respectively fitted on the cutter shaft 8-1-06, and the outer circle of the cylindrical surface bearing 8-1-05 and the outer limiting plate 8-1-09 are respectively fitted on the inner limiting plate 8-1-03 and the outer limiting plate 8-1-09. The inner wall groove of 09 has a rotatable gap with the inner groove of the inner limit plate 8-1-03. When the cutting shaft 8-1-06 rotates, the eccentric sleeve 8-1-04 pushes the cylindrical bearing 8-1-05 to perform a cycloidal motion of inner ring rotation and outer ring rolling, which in turn pushes the circular cutter assembly to move outward horizontally, completing unidirectional cutting. When the cutting shaft 8-1-06 continues to rotate more than 180°, it acts on the inner limit plate 8-1-03 to push the circular cutter assembly to perform a return horizontal movement. Continuous operation completes continuous alternating cutting. The cutting assembly and the circular cutter assembly move up and down synchronously. The reducer, which serves as the power source, is fixed to one side of the reducer plate 8-1-07 by bolts, and the other side is connected to the support shaft 8-1-08. The support shaft 8-1-08 is installed on the circular cutter support assembly by structural threads and locked by nuts to form a rigid connection mechanism. This achieves the anti-rotation of the cutting pull plate 8-1-10 and ensures horizontal movement space.

[0057] like Figure 9 As shown, in some embodiments, the core operating parameter for shearing equipment is the finished pile height of the trimmed fabric. Existing technologies involve manually pressing the pile fibers close to the base fabric using tools such as a straightedge to measure the entire pile height. For ease of operation, this requires stopping the machine for measurement. In situations requiring precise control, frequent machine stops are necessary, resulting in noticeable machine stop marks on the trimmed fabric surface, affecting fabric quality. The present invention... Figure 9As shown, online automatic measurement technology is adopted, solving the problem of real-time measurement without stopping the machine. Its structure consists of a support knife holder 8-6-04, whose two ends can rotate around a central support fixed to the wall panel. The upper end has a support knife edge, and the lower end is hinged to an electric cylinder connector 8-6-01. The front end of the electric cylinder 8-6-02 is connected to the electric cylinder connector 86-01, and the tailstock is hinged to an electric cylinder support 8-6-03 bolted to the wall panel. When the electric cylinder 86-02 executes the controller command, it pushes the support knife holder 86-04 to rotate on a fixed axis. By changing the spatial position of the support knife edge, it compensates for the flat knife and fiber generated during the height adjustment process. The angle of the wire changes; the 8-6-04 scissor holder is equipped with a scissor holder stop 8-6-05 fixed to the wall panel for extreme position protection, preventing the scissor blade from hitting the flat blade or the spiral blade on the round blade when trimming low-height trimming; the automatic adjustment of the trimming height is powered by two servo lifters 8-7-02, which are respectively installed on lifter supports 8-7-03 bolted to the inner side of the wall panel. The lead screw end of the lifter support 8-7-03 is concentrically mounted with a support flange 8-7-01, which serves as a support for the fine-tuning screw on the flat blade holder. The fine-tuning screw is used to adjust the trimming height after the equipment is pre-installed with a manual leveling flat blade holder and the mechanism experiences mechanical wear. The compensation is adjusted; the laser measuring instrument used for online measurement of the gross height is fixed on the support knife holder 8-6-04, located below the annular flange on the round knife used as the measurement reference; the theoretical gross height value formed by trimming is h, that is, the distance from the flat knife edge to the arc edge of the support knife, which is achieved by the change of ΔH1, which drives the fine adjustment bolt to drive the flat knife holder assembly, round knife assembly, etc. to rotate. The change value of ΔH1 is obtained by the PLC reading the target gross height value of the process parameters, performing a series of calculations, converting it into a pulse signal and sending it to the servo lifter 8-7-02 to act. During the lifting process of the servo lifter 8-7-02, the L3 dimension rotates, which in turn drives the L4 dimension to rotate. The relative angle change of the flat blade is converted into the number of action pulses of the electric cylinder 8-6-02 required for L5 dimension compensation angle, and then the angle variable is compensated. After the compensation is completed, the laser measuring instrument measures the change, and the PLC reads and compares the data for confirmation. If there is a difference exceeding the set limit, the PLC calculates the number of compensation pulses, and the servo lift performs fine-tuning compensation. Due to the secondary compensation function with detection and comparison, the accuracy of the trimmed height value is improved many times over, and the automatic compensation of the equipment is achieved within a certain wear range of the blade, which effectively reduces the labor intensity of manual operation and significantly reduces the maintenance downtime of the entire equipment.
