Description

Technical Field

[0001] The present invention relates to the technical field of knitting cloth processing equipment, and in particular discloses a knitting cloth production equipment with a convenient disassembly and cutting mechanism. Background Art

[0002] In the field of knitting cloth production, traditional cutting equipment generally has problems such as single cutting function, cumbersome equipment debugging, high maintenance cost, and insufficient automation. In the prior art, a single knife group structure is difficult to balance the requirements of rough cutting and fine cutting. When replacing the cutting tool, the whole machine needs to be stopped for debugging, resulting in low production efficiency. The method of manually adjusting the tension and deviation correction has insufficient accuracy, which is easy to cause fabric wrinkles, deviation, and even waste, and it is difficult to meet the processing requirements of diversified fabrics. In addition, the linkage of each component of the traditional equipment is poor, and the modularization degree is low. During maintenance, the whole machine needs to be disassembled, which is time-consuming and laborious, and it cannot quickly adapt to the production of knitting cloth with different thicknesses and specifications, restricting the enterprise's response ability to the diversified market demands. With the increasing diversification of knitting cloth product specifications and the strengthening of the trend of automated production, there is an urgent need for a production equipment with flexible cutting function, high-precision control, and convenient maintenance to solve the technical bottlenecks of low efficiency, high cost, and poor adaptability in the traditional process, and to improve the intelligent and flexible level of knitting cloth production.

[0014] Beneficial effects of the present invention:

[0015] (1) The slitting mechanism is easy to disassemble and flexibly adapt to production needs: The slitting mechanism adopts a detachable first knife group and a second knife group design to separate the rough slitting and fine slitting functions. Operators can quickly replace the knife group according to the fabric specifications and switch production tasks without complicated debugging, which greatly shortens the downtime.

[0016] (2) Full-process automated control ensures accuracy and stability: The deviation correction component is linked to the sensor component, and the C-shaped photoelectric sensor is used to monitor the edge deviation of the fabric in real time. The control box drives the carrier plate to dynamically adjust the position of the unwinding shaft to achieve precise deviation correction. The swing arm component and the rheostat form a closed-loop tension control system, which uses the swing roller to provide real-time feedback of tension data and automatically adjust the swing amplitude to avoid wrinkles or breaks in the fabric. The limiter component is combined with the photoelectric component to dynamically adjust the position of the limiter based on beam obstruction to ensure the accuracy of the slitting path and reduce slitting errors and defective rates.

Detailed implementation manners

[0028] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0029] Please refer to Figures 1 to 9As shown in the figure, a knitting fabric production device with a convenient disassembly and cutting mechanism 4 of the present invention includes a frame 1, a unwinding mechanism 2 arranged on the frame 1, a deviation rectifying assembly 3, a cutting mechanism 4, a pressing roller assembly 5, a swing rod assembly 6, an output mechanism 7 and a control box 8; the unwinding mechanism 2 includes a unwinding shaft 21 rotatably arranged on the frame 1 and a magnetic powder brake 22 coaxially arranged at one end of the unwinding shaft 21, and the magnetic powder brake 22 is connected to the output shaft of the power source to adjust the unwinding tension of the unwinding shaft 21; the cutting mechanism 4 includes a first knife group 41 and a second knife group 42 which are detachably connected, the first knife group 41 is used for preliminarily and roughly cutting a large-width knitting fabric into several relatively wide fabric strips, and the second knife group 42 is used for further precisely cutting the fabric strips cut by the first knife group 41; the control box 8 is electrically connected to each mechanism and each component to control the production parameters of the knitting fabric production device.

[0030] During actual use, the combination of the unwinding shaft 21 and the magnetic powder brake 22 in the unwinding mechanism 2 can accurately adjust the unwinding tension, effectively avoiding the problems of slack wrinkles or excessive tightness and damage during the unwinding process of the knitting fabric, ensuring the flat conveying of the fabric, and laying a good foundation for subsequent processes. The cutting mechanism 4 adopts a detachable first knife group 41 and second knife group 42, realizing the step-by-step processing of rough cutting and precise cutting. This design not only improves the cutting efficiency, but also can flexibly replace the knife group according to different production requirements, enhancing the versatility and adaptability of the equipment, and meeting the requirements of diversified knitting fabric cutting specifications.

[0031] The deviation rectifying assembly 3 can monitor and correct the deviation of the knitting fabric in real time, ensuring that the fabric is always on the correct processing path, and reducing the material waste and defective products caused by the fabric running off. The pressing roller assembly 5 and the swing rod assembly 6 cooperate with each other to stably press and orderly convey the cut knitting fabric, ensuring that the fabric remains flat and does not loosen during the transmission process, and improving the quality and stability of the fabric output. The control box 8 is electrically connected to each mechanism and component, realizing the centralized control and precise adjustment of production parameters. The operator can quickly adjust the operating state of the equipment according to production requirements, improve production efficiency, and at the same time ensure the automation and intelligence of the production process, reduce the manual operation intensity and error, and improve the overall production efficiency and product quality.

[0032] The detachable first knife group 41 and second knife group 42 realize the functional separation of rough cutting and precise cutting, can quickly replace the knife group according to different production requirements, and meet the diversified knitting fabric cutting specifications. The disassembly and assembly process is simple and fast, greatly shortening the equipment debugging time, reducing the downtime loss caused by knife replacement, and improving the equipment utilization rate. At the same time, the modular knife group design is convenient for maintenance and repair, reducing the equipment maintenance cost, enabling the operator to replace, clean and maintain the knife more efficiently, ensuring the stable cutting quality, and providing an efficient, flexible and economical solution for knitting fabric production.

[0033] Specifically, the first cutter group 41 includes a cutter cover assembly 43 arranged on the frame 1, a cutter group motor, an upper cutter shaft group 411 rotatably arranged on the frame 1, and a lower cutter shaft group 412; a driving gear 413 is provided on the output shaft of the cutter group motor, driven gears 414 are provided at one end of both the upper cutter shaft group 411 and the lower cutter shaft group 412, the driven gear 414 of the upper cutter shaft group 411 is meshed and connected with the driven gear 414 of the lower cutter shaft group 412, and the driving gear 413 is connected with the driven gear 414 through a transmission belt; the cutter cover assembly 43 has a cutter cover shaft 431 rotatably arranged on the frame 1 and a cutter guard 432 mounted on the cutter cover shaft 431, the cutter guard 432 is located above the cutter shaft, the cutter guard 432 is arranged in an arc shape and a plurality of through holes 433 arranged linearly are provided on the cover surface, and a hand-pulling part 434 is provided on one side of the cutter guard 432 away from the cutter cover shaft 431.

[0034] During actual use, the cutter group motor realizes the synchronous rotation of the upper cutter shaft group 411 and the lower cutter shaft group 412 through the combined transmission of the driving gear 413, the transmission belt and the driven gear 414, ensuring the precise cooperation of the upper and lower cutters during the slitting process, effectively improving the efficiency and quality of rough slitting, and enabling the large-format knitted fabric to be quickly and evenly slit into wider fabric belts. This gear transmission structure has stable power transmission, can reduce the slipping phenomenon during transmission, reduce the risk of equipment failure, and ensure the continuity of production. The setting of the cutter cover assembly 43 greatly improves the safety and practicability of the equipment. The rotatably arranged cutter cover shaft 431 facilitates the operator to flexibly open and close the cutter guard 432. The arc-shaped cutter guard 432 cooperates with the linear through holes 433, which can not only prevent the fabric from splashing and the cutter from accidentally injuring people during the slitting process, but also does not affect observing the running state of the cutter and the slitting situation of the fabric, ensuring operation safety while facilitating real-time monitoring of the production status.

[0035] The design of the hand-pulling part 434 conforms to ergonomics, facilitating the operator to quickly and easily open and close the cutter guard 432, reducing the operation difficulty and labor intensity. In addition, this structural design makes the maintenance, repair and tool replacement of the first cutter group 41 more convenient. The operator can quickly access the cutter by opening the cutter guard 432, shortening the maintenance time, reducing the equipment downtime loss, improving the equipment utilization rate. At the same time, the standardized structural layout also facilitates the subsequent maintenance of the cutter group motor, transmission components, etc., further enhancing the stability and reliability of the equipment, and helping the knitted fabric production to operate efficiently, safely and stably.

[0036] In the tool guard assembly 43, the rotatable tool guard 432 is paired with a hand-pulling part 434, which facilitates quick opening and closing by the operator. When replacing the tool or repairing the tool shaft, the internal structure can be easily exposed, significantly shortening the disassembly and assembly time. The upper and lower tool shaft groups 412 are connected to the tool group motor through gears and transmission belts. This transmission method features a compact structure with independent components. When a fault occurs, it can be accurately positioned and quickly disassembled for repair or replacement. At the same time, this modular structure makes the overall replacement of the tool group more convenient. Different specifications of tools can be quickly switched according to production needs, improving the equipment's response speed to diverse production tasks, effectively enhancing production efficiency, and reducing maintenance costs.

[0037] Specifically, the second tool group 42 includes an upper tool holder 421, a lower tool holder 422, and a camshaft group 423. The camshaft group 423 is driven to rotate via a cam driver. The lower tool holder 422 is fixed on the frame 1, and the upper tool holder 421 is movably connected to the camshaft group 423 to form a cam-linkage mechanism. The upper tool holder 421 realizes the cloth-cutting action of opening and closing through the cam-linkage mechanism.

[0038] During actual use, the camshaft group 423 rotates precisely under the drive of the cam driver. Through the ingeniously constructed cam-linkage mechanism, the rotational motion is efficiently converted into the linear reciprocating opening and closing motion of the upper tool holder 421, enabling the upper tool holder 421 to cooperate with the fixed lower tool holder 422 to achieve precise fine-cutting of the cloth tape after rough cutting. This transmission method can provide a stable and regular motion trajectory. Compared with traditional transmission structures, it can ensure that the tool contacts the fabric with a constant pressure and speed during the cutting process, avoiding problems such as frayed edges and tearing of the fabric caused by uneven force or speed fluctuations, greatly improving the cutting accuracy and the quality of the fabric finished product. At the same time, the cam-linkage mechanism has a compact structure, high transmission efficiency, and small space occupation, which is conducive to optimizing the overall layout of the equipment and realizing the efficient cutting function within the limited space of the frame 1.

[0039] Its stable transmission performance can also reduce the noise and vibration during the operation of the equipment, reduce mechanical wear, extend the service life of the equipment, and lower maintenance costs. In addition, the cam driver is easy to adjust and control. It can flexibly adjust the rotation speed of the camshaft group 423 and the action parameters of the upper tool holder 421 according to knitted fabrics of different thicknesses and materials, meeting diverse fine-cutting requirements, enhancing the versatility and adaptability of the equipment, enabling the equipment to easily handle the production tasks of different specifications of knitted fabrics, and providing a reliable guarantee for the efficient, precise, and flexible operation of knitted fabric production.

[0040] The movable connection method between the upper tool holder 421 and the camshaft group 423 enables convenient disassembly of the tool assembly. Operators can quickly replace worn tool holders or cam components, reducing downtime. The independent control feature of the cam driver allows for adjustment of slitting parameters such as rotational speed and pressure without disassembling the entire mechanism, adapting to different fabric processing requirements. The compact structural layout reduces the number of connecting parts, lowering the complexity of disassembly and assembly. Meanwhile, the modular design enables the entire tool group to be quickly replaced, facilitating equipment upgrade or maintenance. This design not only ensures high-precision slitting quality but also greatly improves production flexibility and maintenance efficiency, embodying the core advantages of the easily disassembled and assembled slitting mechanism 4.

[0041] Specifically, the deviation rectifying assembly 3 includes a carrier 31 arranged on the frame 1, a carrier plate 32 slidably arranged on the carrier 31 and capable of moving along the axial direction of the unwinding shaft 21, and a deviation rectifying driver 33 for driving the linear motion of the carrier plate 32; the unwinding shaft 21 is installed on the carrier plate 32, and a rotatable deviation rectifying guide roller 34 is further arranged on the carrier plate 32. The unwinding shaft 21 and the deviation rectifying guide roller 34 are respectively installed on the upper and lower sides of the carrier plate 32; the carrier plate 32 is provided with a fixed shaft 35, and the output shaft of the deviation rectifying motor is provided with an annular part 36 sleeved on the fixed shaft 35. The deviation rectifying motor drives the carrier plate 32 to reciprocate through the annular part 36 and the fixed shaft 35 to achieve the deviation rectifying action.

[0042] During actual use, the sliding fit between the carrier 31 and the carrier plate 32, combined with the drive of the deviation rectifying driver 33, constructs a flexible and stable moving structure, enabling the unwinding shaft 21 to accurately move along the axial direction, effectively solving the problem of deviation of knitted fabric during the unwinding process caused by uneven tension, equipment installation errors, etc. The unwinding shaft 21 and the deviation rectifying guide roller 34 are respectively installed on the upper and lower sides of the carrier plate 32 to form a stable fabric transmission path. When the fabric deviates, the deviation rectifying motor, through the linkage of the annular part 36 and the fixed shaft 35, accurately drives the carrier plate 32 to reciprocate, timely adjusting the positions of the unwinding shaft 21 and the deviation rectifying guide roller 34, thereby correcting the deviation direction of the fabric and ensuring that the fabric is always smoothly conveyed along the predetermined path, reducing cutting deviations, material waste, etc. caused by fabric deviation.

[0043] This structural design enables the deviation rectifying action to respond quickly and adjust precisely, capable of real-time monitoring and correcting small deviations of the fabric, avoiding the generation of a large number of defective products caused by the accumulation of deviations. In addition, the deviation rectifying assembly 3 is independently arranged and easy to maintain. The connection structure between the carrier plate 32 and each component is simple and reliable. During equipment maintenance or when changing the fabric specification, operators can quickly adjust and maintain the assembly, reducing equipment downtime and improving production efficiency. Meanwhile, its modular design can be adapted to different models of knitted fabric production equipment, enhancing the versatility and applicability of the equipment, providing a strong guarantee for the continuity and stability of knitted fabric production, and effectively improving the production efficiency and product quality of the enterprise.

[0044] Specifically, a sensor assembly 11 is provided on the frame 1 in cooperation with the deviation rectifying assembly 3. The sensor assembly 11 includes a deviation rectifying inductor shaft 111 mounted on the frame 1 and a deviation rectifying sensor 112 mounted on the deviation rectifying inductor shaft 111. The deviation rectifying sensor 112 forms a C-shaped structure, and the side of the knitted fabric roll passes through the C-shaped opening of the C-shaped structure. The deviation rectifying sensor 112 feeds back the position signal of the knitted fabric roll to the control box 8 to control the deviation rectifying assembly 3 to perform a deviation rectifying action.

[0045] In actual use, the deviation rectifying inductor shaft 111 is stably mounted on the frame 1, providing reliable support for the deviation rectifying sensor 112 to ensure its stability during the operation of the equipment and accurately capture the position information of the knitted fabric roll. The deviation rectifying sensor 112 with a C-shaped structure is ingeniously designed, enabling the side of the knitted fabric roll to smoothly pass through the C-shaped opening, realizing all-round real-time monitoring of the edge position of the fabric. This structure can not only effectively avoid direct friction between the fabric and the sensor, reducing equipment wear, but also accurately sense extremely subtle offsets of the fabric, greatly improving the monitoring sensitivity. The deviation rectifying sensor 112 quickly and accurately feeds back the collected fabric position signal to the control box 8. The control box 8 quickly analyzes the degree of fabric offset based on the preset parameters and the feedback signal, and promptly issues an instruction to control the deviation rectifying assembly 3 to perform a deviation rectifying action.

[0046] This automated closed-loop control mechanism greatly improves the deviation rectifying response speed, can correct the deviation when the fabric just starts to deviate, prevent the deviation problem from expanding, ensure that the fabric is always conveyed along the correct path, effectively reduce slitting errors, fabric waste, etc. caused by fabric deviation, and significantly improve product quality and production efficiency. At the same time, the non-contact monitoring method of the sensor assembly 11 reduces the daily maintenance frequency and cost of the equipment, is easy to install and debug, works in coordination with the deviation rectifying assembly 3, endows the knitted fabric production equipment with intelligent and automated characteristics, and meets the requirements of modern industrial high-efficiency and precision production.

[0047] Specifically, the swing rod assembly 6 includes a swing rod shaft 61 rotatably provided on the frame 1, a limit post 62, a connecting plate 63 mounted on the swing rod shaft 61, and a swing roller 64 rotatably provided on the connecting plate 63. One end of the swing rod shaft 61 is driven to rotate by a swing rod driver. A transmission gear 65 is provided between the swing rod shaft 61 and the swing rod driver. The transmission gear 65 is meshed and connected to a gear shaft 66 mounted on the frame 1. A variable resistor 67 is coaxially provided at the end of the gear shaft 66. The number of the limit posts 62 is set to be multiple. The multiple limit posts 62 are used to limit the rotation angle of the connecting plate 63 around the swing rod shaft 61. Both the swing rod assembly 6 and the variable resistor 67 are electrically connected to the control box 8. The swing rod assembly 6 adjusts the tension of the knitted fabric roll material in real time through a swinging action. The variable resistor 67 converts the change in the tension of the roll material into an electrical signal and feeds it back to the control box 8. The control box 8 dynamically adjusts the swinging amplitude and frequency of the swing rod assembly 6 based on the electrical signal data to form a closed-loop tension control system.

[0048] During actual use, the swing rod shaft 61 is driven by the swing rod driver through the transmission of the transmission gear 65 and the gear shaft 66, driving the connecting plate 63 and the swing roller 64 to rotate flexibly. The tension of the knitted fabric roll material is sensed and adjusted in real time through the swinging action. The multiple limit posts 62 accurately limit the rotation angle of the connecting plate 63, ensuring that the swing rod assembly 6 operates within a safe and effective range, and preventing the fabric transmission and equipment safety from being affected due to excessive or out-of-control swinging amplitude. The variable resistor 67 accurately converts the change in the roll material tension into an electrical signal and feeds it back to the control box 8, enabling the control box 8 to obtain the dynamic data of the fabric tension in real time. Based on these accurate electrical signal data, the control box 8 can quickly and accurately calculate the parameters that need to be adjusted, and then dynamically adjust the swinging amplitude and frequency of the swing rod assembly 6 to achieve fine control of the fabric tension.

[0049] This closed-loop control system can promptly respond to the tension changes caused by factors such as fabric thickness variation and unwind speed fluctuation during the production process, automatically maintain the stability of the fabric tension, effectively avoid problems such as fabric wrinkles, stretching deformation, and breakage caused by uneven tension, and significantly improve the finished product quality of the knitted fabric. At the same time, the closed-loop control mechanism reduces the frequency and difficulty of manual intervention, reduces the risk of production accidents caused by human operation errors, and improves the production efficiency and the stability of equipment operation. In addition, the modular design of this system facilitates installation, debugging, and maintenance, can adapt to the production requirements of different specifications of knitted fabrics, enhances the versatility and practicality of the equipment, and provides strong support for knitted fabric production enterprises to enhance competitiveness and reduce production costs.

[0050] Specifically, the frame 1 is provided with a limiting component 12 located between the first knife group 41 and the second knife group 42. The limiting component 12 includes a horizontally arranged limiting plate 121, a strip-shaped hole 122 provided on the limiting plate 121, and a limiting member 123 installed in cooperation with the strip-shaped hole 122. The limiting plate 121 contacts the bottom surface of the coiled material, and the limiting member 123 is used to limit the position of the knitted fabric coiled material. The limiting member 123 adjusts its installation position along the strip-shaped hole 122.

[0051] During actual use, the horizontally arranged limiting plate 121 is in close contact with the bottom surface of the coiled material, forming a stable support plane, effectively preventing the knitted fabric from sagging or shifting due to gravity during transmission, ensuring that the fabric remains flat in the slitting path, and laying a good foundation for the subsequent slitting process. The cooperative design of the strip-shaped hole 122 and the limiting member 123 is extremely flexible and practical. Operators can flexibly adjust the installation position of the limiting member 123 along the strip-shaped hole 122 according to coiled materials of different specifications and widths, thereby accurately defining the transmission path and slitting boundary of the fabric. This adjustable limiting method can not only meet diverse production requirements but also quickly adapt to the processing of different batches of fabrics, greatly enhancing the versatility and adaptability of the equipment.

[0052] By arranging the limiting component 12 between the rough slitting of the first knife group 41 and the fine slitting of the second knife group 42, it can effectively prevent the fabric from deviating in position during the transition stage between the two slittings, ensure that the cloth tape after rough slitting enters the second knife group 42 in an ideal position, thereby improving the accuracy of fine slitting and the finished product quality, and reducing the slitting error and defective rate caused by improper fabric movement. In addition, the limiting component 12 has a simple structure and is convenient to install. Daily maintenance and adjustment operations are easy to perform, reducing the equipment maintenance cost and the working intensity of operators. At the same time, the stable limiting effect also helps to extend the service life of the slitting tool, improve the reliability and production efficiency of the overall equipment operation, and provide a reliable guarantee for the efficient and accurate operation of knitted fabric production.

[0053] Specifically, the frame 1 is provided with an optoelectronic component 13 in cooperation with the limiting component 12. The optoelectronic component 13 is located above the limiting component 12. The optoelectronic component 13 includes a slide rail 131 provided on the frame 1, a slide plate 132 slidably arranged on the slide rail 131, and an electro-optical eye component 133 installed on the slide plate 132. The slide plate 132 realizes horizontal position adjustment through the slide rail 131. The detection beam emitted by the electro-optical eye component 133 irradiates the surface of the coiled material. When the area of the beam blocked changes due to the edge offset of the coiled material, the electro-optical eye component 133 converts the optical signal into an electrical signal and transmits it to the control box 8. The control box 8 drives the limiting member 123 to move to a specified position along the strip-shaped hole 122 based on a preset threshold, forming a dynamic edge positioning system based on optoelectronic detection.

[0054] During actual use, the combination of the slide rail 131 and the slide plate 132 endows the electric eye assembly 133 with flexible lateral adjustment capabilities. Operators can quickly adjust the position of the electric eye assembly 133 according to the widths of different knitted fabric rolls, enabling its detection beam to accurately cover the edge area of the fabric and adapting to diverse production requirements. The detection beam emitted by the electric eye assembly 133 monitors the surface of the roll in real time. When the fabric edge shifts due to factors such as tension changes during transmission and equipment vibration, the area of the beam occlusion changes accordingly. The electric eye assembly 133 quickly converts this optical signal into an electrical signal and transmits it to the control box 8. The control box 8 analyzes and processes the electrical signal based on a preset threshold. Once it determines that the fabric deviation exceeds the allowable range, it immediately drives the limiting member 123 in the limiting assembly 12 to move to a specified position along the strip-shaped hole 122, timely correcting the fabric position and forming a fast-response closed-loop control process.

[0055] This dynamic positioning mechanism based on photoelectric detection significantly improves the timeliness and accuracy of fabric edge positioning compared to traditional manual monitoring and manual adjustment. It can intervene instantly when the fabric shifts, effectively avoiding cutting errors caused by the accumulation of deviations and reducing the defective product rate. At the same time, this system reduces manual participation, lowers labor intensity and human errors, and improves production efficiency and automation level. In addition, the modular photoelectric components 13 are easy to install and debug, and work stably and reliably in coordination with the limiting assembly 12, enhancing the overall operation stability and reliability of the equipment, providing a solid technical guarantee for high-precision and high-efficiency processing of knitted fabric production, and helping enterprises improve product quality and market competitiveness.

[0056] Specifically, the pressing roller assembly 5 includes a first pressing roller assembly 51 disposed after the first knife group 41 and a second pressing roller assembly 52 disposed after the second knife group 42. The pressing roller assembly includes an upper pressing roller 53 and a lower pressing roller 54 rotatably provided on the frame 1. The upper pressing roller 53 and the lower pressing roller 54 are arranged in parallel. The frame 1 is provided with a mounting seat 56 for mounting the upper pressing roller 53 and an adjusting assembly 55 for driving the mounting seat 56 to reciprocate. The adjusting assembly 55 adjusts the upper pressing roller 53 to approach or move away from the lower pressing roller 54 through the mounting seat 56 to adapt to knitted fabric rolls of different thicknesses.

[0057] In actual use, the first pressure roller assembly 51 and the second pressure roller assembly 52 are respectively arranged behind the first knife group 41 and the second knife group 42, which can compact and flatten the cloth in time after rough slitting and fine slitting, effectively eliminate the wrinkles, looseness and other problems generated during the slitting process, ensure that the cloth enters the subsequent process in a flat state, and improve the cloth quality and processing accuracy. The structural design of the upper pressure roller 53 and the lower pressure roller 54 arranged in parallel can evenly apply pressure to the surface of the cloth, ensure that the cloth is evenly stressed, and avoid deformation or damage to the cloth due to uneven pressure. The coordination between the mounting seat 56 and the adjustment assembly 55 is a highlight. The adjustment assembly 55 can drive the mounting seat 56 to flexibly reciprocate, and then accurately adjust the upper pressure roller 53 to approach or move away from the lower pressure roller 54. This adjustable design can quickly adapt to knitted cloth rolls of different thicknesses.

[0058] Whether it is a thin, soft and easily deformed fabric, or a thick, hard fabric, the pressing roller assembly 5 can adjust the pressure so that the upper and lower pressing rollers 54 fit tightly with the fabric without damaging the fabric, ensuring that the fabric remains stable during transmission and preventing slipping and deviation. At the same time, this structure reduces the restrictions of the equipment on fabric specifications, enhances the versatility and applicability of the equipment, and reduces the time and cost of frequent equipment adjustments due to changes in fabric specifications. In addition, the pressing roller assembly 5 has a simple structure and is easy to maintain. The stable pressing effect helps to extend the service life of the slitting tool, improve the overall operating efficiency and production benefits of the equipment, and provide strong support for the efficient and stable operation of knitted fabric production.

[0059] Specifically, the output mechanism 7 includes a fixing part 72, a discharge plate 71 and a support assembly 73. The two ends of the discharge plate 71 along the discharge direction of the knitted fabric are supported and fixed by the fixing part 72 and the support assembly 73 respectively; the support assembly 73 includes a sliding sleeve 74, a sliding rod 75 and a locking part 76. The sliding rod 75 slides through the sliding sleeve 74 and is fixed by the locking part 76. The end of the sliding sleeve 74 is movably connected to the frame 1, and the bottom of the discharge plate 71 is movably connected to the end of the sliding rod 75.

[0060] In actual use, the fixing member 72 and the support assembly 73 support the two ends of the discharge plate 71 respectively, and build a stable bearing structure to ensure that the discharge plate 71 remains stable when receiving the knitted fabric after slitting, avoiding poor fabric delivery or wrinkles on the surface due to shaking, and providing reliable protection for fabric output. The sliding matching design of the sliding sleeve 74 and the sliding rod 75 in the support assembly 73 is very ingenious. The operator can flexibly adjust the extension length of the sliding rod 75 in the sliding sleeve 74 according to actual production needs, thereby changing the height and tilt angle of the discharge plate 71 to adapt to the discharge requirements of knitted fabrics of different specifications. For example, thick fabrics require a larger tilt angle for smooth discharge, and thin fabrics require precise height control to prevent pulling and deformation.

[0061] This adjustable feature significantly enhances the versatility of the equipment and reduces the cost and time loss of replacing the output device due to changes in fabric specifications. The setting of the locking member 76 can firmly fix the slide bar 75 in the adjusted position, ensuring the stability of the structure of the discharge plate 71 during the output process. Even if it runs for a long time, it will not loosen or shift, ensuring stable output of the fabric. At the same time, the movable connection between the end of the slide sleeve 74 and the frame 1, the bottom of the discharge plate 71 and the end of the slide bar 75, on the basis of flexible adjustment, also facilitates the installation, disassembly and maintenance of the equipment. When the equipment fails or the layout needs to be adjusted, the operator can quickly inspect and adjust the output mechanism 7, effectively improve the equipment maintenance efficiency, reduce downtime, and help the knitted fabric production to be carried out efficiently and stably, providing strong support for enterprises to improve production efficiency and product quality.

[0062] In this embodiment, the first knife group 41 and the first pressure roller assembly 51 are connected via a first gear-belt transmission structure 14, and the frame 1 is provided with a first drive motor 15 acting on the first gear-belt transmission structure 14; the second knife group 42 and the second pressure roller assembly 52 are connected via a second gear-belt transmission structure 16, and the frame 1 is provided with a second drive motor 17 acting on the second gear-belt transmission structure 16.

[0063] In actual use, the gear-belt transmission structure combines the accuracy of gear transmission with the buffering and shock-absorbing characteristics of belt transmission, which can ensure that the upper knife shaft group 411 and the lower knife shaft group 412 of the first knife group 41 and the upper and lower pressure rollers 54 of the first pressure roller assembly 51 rotate synchronously, realize the precise engagement of the knives and the uniform pressure of the pressure rollers during rough slitting, and absorb the impact load during operation through the elastic deformation of the transmission belt, reduce the damage to the transmission system caused by sudden changes in cloth tension or equipment vibration, and improve the stability of equipment operation. The independent first drive motor 15 and the second drive motor 17 can respectively adjust the power output of the rough slitting and fine slitting processes. The operator can flexibly adjust the parameters of the two groups of transmission systems according to the characteristics of the cloth (such as thickness and elasticity). For example, by replacing gears with different numbers of teeth or adjusting the tension of the belt drive, the fine control of the slitting speed and the pressure of the pressure roller can be achieved, which can not only meet the strong slitting force required for thick cloth, but also avoid the deformation of thin cloth due to excessive extrusion during processing, and significantly enhance the process adaptability of the equipment.

[0064] The physical isolation design of the dual-drive system effectively avoids the process interference problem in the traditional single-drive mode. When a certain cutter group or pressure roller assembly needs maintenance, the corresponding drive system can be independently shut down, while the other system can still operate normally, ensuring production continuity and reducing production capacity losses caused by the shutdown of the whole machine. In addition, the modular design of the gear-belt drive structure facilitates quick disassembly, installation and maintenance. The replacement of the drive belt does not require complex tools, and the standardized design of the gear assembly also reduces the spare part cost. With the frequency conversion control function of the drive motor, the equipment can achieve efficient switching in different production scenarios, further improving production efficiency and the level of intelligence. This innovative drive solution provides comprehensive guarantee for the high-precision and high-reliability processing of knitted fabric production through the organic combination of precise transmission, independent control, anti-interference ability and convenient maintenance, helping enterprises achieve flexible production in diverse market demands.
