Description

Technical Field

[0001] This utility model relates to the field of textile equipment, and more specifically, it relates to a multi-functional machine for sizing and attaching lint to knitted and woven fabrics. Background Technology

[0002] The textile industry often involves many different steps in fabric processing, including fabric feeding, sizing, drying, washing, and lint removal. Each step requires corresponding textile equipment, which has led to the emergence of multi-functional sizing machines that integrate sizing, drying, and other functions.

[0003] For example, Chinese Patent No. CN208395456U discloses a fabric sizing machine based on inkjet printing. Its key technical features are: it includes a sizing tank, a drying box, and a roll-up device. The drying box is equipped with a fabric conveyor belt that runs through the box. The feed end of the fabric conveyor belt is equipped with a corresponding hard bristle pressing wheel. An intermediate roller is provided between the discharge end of the sizing tank and the feed end of the drying box. An intermediate roller is provided between the discharge end of the drying box and the feed end of the roll-up device. The feed end of the roll-up device is also equipped with a trimming wheel for trimming the side of the fabric.

[0004] In the textile industry, knitted and woven fabrics exhibit distinctly different characteristics due to the different forms of yarn within the fabric. Knitted fabrics typically possess better elasticity and extensibility, while woven fabrics exhibit structural stability and a smooth surface. On fabric production lines, the fabric exiting the sizing machine directly enters downstream textile equipment. Because of the significant differences in characteristics between knitted and woven fabrics, knitted fabrics require lower tension and a shorter stroke from the sizing machine's output structure to quickly enter the downstream textile equipment and avoid edge curling. Conversely, woven fabrics require higher tension and a longer stroke from the sizing machine's output structure to maintain a smooth surface before entering the downstream equipment. Existing multi-functional sizing machines cannot simultaneously handle both knitted and woven fabrics, thus necessitating a new solution to address this issue. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-functional machine for sizing and lint-removing knitted and woven fabrics.

[0011] The fabric correction roller is located downstream of the tension adjustment frame and the tension release frame, and is a universal correction device for both knitted and woven fabrics.

[0012] The fabric edge detection mechanism is located downstream of the fabric feeding correction roller. It monitors the edge position of knitted or woven fabrics in real time and generates feedback signals. It then corrects the subsequent fabric through the upstream fabric feeding correction roller.

[0013] The fabric raising synchronous roller, tension adjustment frame, guide roller and fabric exit correction roller sequentially form the fabric exit path of the woven fabric;

[0014] The fabric feeding synchronous roller, tension release frame, and fabric exit correction roller sequentially form the fabric exit path of the knitted fabric.

[0015] The present invention is further configured such that: the tension release frame is provided with a plurality of rollers, and the plurality of rollers and the fabric raising synchronous roller are driven by the same driving mechanism.

[0016] The present invention is further configured such that the roller body is a filament splitting roller.

Detailed Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0029] A multi-functional machine for feeding, sizing, and linting fabric, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes a frame 1, a fabric feeding mechanism, a sizing mechanism 14, a conveyor belt mechanism, and a fabric output mechanism, wherein:

[0030] The fabric feeding mechanism includes a guide rod 16, a fabric tensioner 17, a fabric feeding and correction roller 15, a flattening roller 18, and a pressure roller 19. The guide rod 16 is a smooth, curved metal rod installed at the inlet of the frame 1 to ensure that the fabric enters the subsequent process smoothly, reducing wrinkles or mechanical jamming caused by path deviation, guiding the fabric along a predetermined path, and preventing deviation or entanglement. The fabric tensioner 17 adjusts the tension through a mechanical or pneumatic device to prevent the fabric from being too loose (leading to accumulation) or too tight (leading to deformation or breakage), and is used for adjustment and control. The fabric tension is maintained at a uniform tightness, ensuring stable tension during continuous processing and ensuring process consistency. The feed correction roller 15 detects the position of the fabric edge through a sensor, ensuring that the fabric always runs in the center and automatically corrects the lateral position deviation of the fabric in the equipment. The flattening roller 18 has a spiral pattern on its surface, which applies a lateral expansion force to the fabric through rotation, eliminating wrinkles or curling on the fabric surface and making it flat and unfolded. The pressing roller 19 applies pressure through a structure such as a cylinder, making the fabric fit tightly against the conveyor belt mechanism. Knitted fabric 32 enters the conveyor belt 24 of the conveyor belt mechanism through the guide rod 16, the tensioner 17, the feed correction roller 15, the flattening roller 18, and the pressing roller 19 for subsequent processes. Woven fabric 31 enters the conveyor belt 24 of the conveyor belt mechanism through the tensioner 17, the feed correction roller 15, the flattening roller 18, and the pressing roller 19 for subsequent processes. The guide rod 16, the tensioner 17, the feed correction roller 15, the flattening roller 18, and the pressing roller 19 are all commonly used components in fabric processing equipment and are conventional structures well-known to those skilled in the art. Therefore, their mechanical structure and control principle will not be elaborated here. The feed correction roller 15, in conjunction with the subsequent output correction roller 6, forms a secondary correction, improving the flatness of both knitted fabric 32 and woven fabric 31.

[0031] The sizing mechanism 14 is a rotary screen sizing device or a gravure screen sizing device, and several sets of rotary screen sizing devices or gravure screen sizing devices can be set. In this embodiment, the sizing mechanism 14 is a rotary screen sizing device, which includes a rotary screen 20 and an iron rod 21 located inside the rotary screen 20. The frame 1 is provided with an adjustable magnetic platform 22 for adsorbing the iron rod 21. The sizing function in this embodiment is realized through the rotary screen 20 structure. An iron rod 21 is placed inside the rotary screen 20, and a magnetic platform 22 with an applied magnetic force is placed under the conveyor belt 24. After being energized, a magnetic force is generated to adsorb the iron rod 21, thereby achieving adjustable pressure on the sizing material. Compared to traditional immersion sizing, this method allows for precise control of sizing thickness on fabrics of varying thicknesses, saving significant amounts of sizing material and greatly reducing costs. The rotary screen sizing device sizes only one side of the fabric, minimizing sizing usage and eliminating the need for additional drying equipment during the sizing-to-printing process. Furthermore, it ensures uniform sizing. For special fabrics requiring small sizing amounts, the sizing method can be changed to gravure sizing with a smaller output. For special fabrics requiring large sizing amounts, a two- or multi-color rotary screen 20 and gravure can be added to the existing single-set rotary screen 20 and gravure, achieving precise control of the sizing amount. For knitted fabrics 32 and woven fabrics 31, the pressure of the sizing mechanism 14 can be adaptively adjusted via the pressure control of the magnetic table 22. Both rotary screen sizing devices and gravure sizing devices are commonly used components in fabric processing equipment and are conventional structures well-known to those skilled in the art; therefore, their mechanical structures and control principles will not be elaborated upon here.

[0032] The frame 1 is equipped with a penetrating roller 23 located behind the sizing mechanism 14, which is used to provide secondary pressure to the sized fabric surface. The penetrating roller 23 can be adjusted up and down. The adjustment method can be a linear reciprocating adjustment method commonly used in mechanical fields, such as cylinder drive, hydraulic cylinder drive, or screw structure. Therefore, it will not be described in detail here. The penetrating roller 23 behind the rotary screen 20 can provide secondary pressure to the sized fabric surface, making the sizing surface more uniform and the sizing material penetrating into the fabric surface better. The penetrating roller 23 achieves uniform liquid penetration through high pressure extrusion, which directly affects the color fastness and functional finishing effect. Another key technical point is the pressure control accuracy. The vertically adjustable penetrating roller 23 can easily control the pressure of the penetrating roller 23.

[0033] The conveyor belt mechanism includes a conveyor belt 24 for conveying fabric. A cleaning device is mounted on the frame 1 for cleaning the conveyor belt 24. By incorporating the conveyor belt mechanism and cleaning device, adhesive can be applied to the conveyor belt 24, allowing the fabric to be processed synchronously with the conveyor belt 24. It can also remove lint and debris from the fabric surface, which is then immediately washed away by the cleaning device, achieving a fabric cleaning function. Furthermore, if no sizing is applied, this device can also be used independently as a fabric lint remover, broadening its functionality. Specifically, the cleaning device includes a frame 25 and a... The frame 25 is provided with a washing component 26, a drying component 27, and a scraper component 28 arranged in sequence. The washing component 26 sprays water onto the conveyor belt 24 through a water nozzle, which can wash away the lint and debris stuck to the conveyor belt 24. Correspondingly, a water storage tank is provided below the frame 25 for storing water. The drying component 27 wipes the conveyor belt 24 with a soft material wiping block, which can further clean the lint and debris on the conveyor belt 24. The scraper component 28 squeezes the conveyor belt 24 with a scraper to achieve an effective water scraping effect and can also scrape away more stubborn debris.

[0034] The above mechanisms enable the multi-functional sizing and lint-removing machine for knitted and woven fabrics to achieve the same effect. These mechanisms can also be applied to both knitted fabric 32 and woven fabric 31, and are suitable for both types of fabrics.

[0035] The core invention of this utility model lies in the fabric dispensing mechanism, which includes:

[0036] Fabric raising synchronous roller 2, such as Figure 4 and Figure 5 As shown, this is used for conveying fabric after sizing;

[0037] Tension adjustment bracket, such as Figure 1 and Figure 3 As shown, it is located downstream of the fabric raising synchronous roller 2 and is used for tension adjustment and conveying of the woven fabric 31;

[0038] Tension release frame 3, such as Figure 4 As shown, a tension release chamber 4 is set downstream of the fabric raising synchronous roller 2 for conveying and releasing the tension of the knitted fabric 32. It includes a tension release chamber 4 for relaxing the knitted fabric 32, so that the knitted fabric 32 forms a relaxed forward path in the chamber, thereby releasing the tension and preventing curling. Furthermore, several roller bodies 8 are mounted on the tension release frame 3 through bearing seats. The roller bodies 8 and the fabric raising synchronous roller 2 are driven by the same drive mechanism. This same drive mechanism is a motor and pulley assembly, which is a commonly used drive mechanism in the mechanical field, so it will not be described in detail here. The roller body 8 can play the role of transporting the knitted fabric 32. Preferably, the roller body 8 is a splitting roller. The splitting roller can flatten the knitted fabric 32 through the thread structure on its surface, preventing the fabric from wrinkling or curling.

[0039] Guide roller 5, such as Figure 1 As shown, it is fixed to the frame 1 by bearing seat and set downstream of the tension adjustment frame. It is used for conveying woven fabric 31 and can also change the forward angle of woven fabric 31 to facilitate its entry into the downstream fabric output correction roller 6 for correction.

[0040] Fabric straightening roller 6, such as Figure 1 and Figure 4 As shown, it is located downstream of the tension adjustment frame and tension release frame 3, and is a universal correction device for knitted fabric 32 and woven fabric 31. Its principle and control method are the same as the feed correction roller 15. The combination of the two can form a secondary correction effect.

[0041] Fabric edge inspection agency 7, such as Figure 1 and Figure 4 As shown, the device is located downstream of the fabric feeding correction roller 6. It monitors the edge position of the knitted fabric 32 or woven fabric 31 in real time and generates a feedback signal. It then corrects the subsequent fabric through the upstream fabric feeding correction roller 6. It uses a photoelectric through-beam sensor with the transmitter and receiver located on both sides of the fabric edge. When the fabric edge deviates, the light signal at the receiver changes and is converted into an electrical signal, which is fed back to the correction roller control system of the fabric feeding correction roller 6 to trigger the correction action.

[0042] The fabric raising synchronous roller 2, tension adjustment frame, guide roller 5, and fabric exit correction roller 6 sequentially form the fabric exit path of woven fabric 31; the fabric raising synchronous roller 2, tension release frame 3, and fabric exit correction roller 6 sequentially form the fabric exit path of knitted fabric 32. By setting two sets of transportation systems on the fabric exit mechanism for transporting woven fabric 31 and knitted fabric 32, and by using corresponding parameter control, the fabric raising synchronous roller 2, tension adjustment frame, guide roller 5, and fabric exit correction roller 6 can form the fabric exit path of woven fabric 31, and the fabric raising synchronous roller 2, tension adjustment frame, guide roller 5, and fabric exit correction roller 6 can form the fabric exit path of knitted fabric 32. Through the dual-path design, the differences between knitted fabric 32 and woven fabric 31 are adapted, so that the sizing multi-functional function can simultaneously meet the fabric exit requirements of both knitted fabric 32 and woven fabric 31.

[0043] Furthermore, such as Figure 4 and Figure 5 As shown, Figure 1 and Figure 4As shown, the fabric lifting synchronous roller 2 includes: two rollers 29: the core components of the fabric lifting synchronous roller 2, typically made of high-strength materials, used for supporting and conveying materials; synchronous pulleys 30: fixed at both ends of the rollers 29, used to cooperate with the synchronous belt to achieve synchronous rotation of the two rollers 29; a synchronous belt: wrapped around multiple synchronous pulleys 30, driving the rollers 29 to rotate through friction, thus conveying materials; a drive device: typically a motor or geared motor, used to provide power to drive the synchronous pulleys 30 and the synchronous belt to rotate; and a tensioning device: used to adjust the tension of the synchronous belt to ensure good cooperation between the synchronous belt and the synchronous pulleys 30. One roller 29 is used for transporting the fabric above the conveyor belt 24, and the other is used for driving the conveyor belt 24, thereby achieving synchronous movement of the fabric and the conveyor belt 24.

[0044] like Figure 1 and Figure 3 As shown, the tension adjustment frame includes a rotating frame 9, a tension sensor, an adjusting roller 10, and a drive cylinder 11. The rotating frame 9 is rotatably connected to the machine frame 1. The output end of the drive cylinder 11 is movably connected to one side of the rotating frame 9. Specifically, the piston rod of the drive cylinder 11 is movably connected to the free end of the rotating frame 9 through a fisheye joint. The rotating frame 9 swings around the hinge axis, and the output end of the drive cylinder 11 moves up and down, which can drive the rotating frame 9 to rotate. The adjusting roller 10 is rotatably connected to the rotating frame 9 through a bearing seat, and as the rotating frame 9 rotates, it realizes a vertical arc motion, thereby changing the fabric wrap angle and adjusting the tension to control the tension of the woven fabric 31. A tension sensor monitors the fabric tension in real time (a commonly used sensor in fabric processing, not shown in the figure) and adjusts it via a drive cylinder 11 to achieve precise control of the fabric tightness. Specifically, it is installed next to the bearing seat of the adjusting roller 10, and detects the tension value of the woven fabric 31 in real time, forming a closed-loop control with the drive cylinder 11: when the tension is too high, the cylinder piston rod moves upward → the rotating frame 9 swings upward → the adjusting roller 10 moves upward → the fabric wrap angle decreases → the tension decreases; when the tension is too low, the cylinder piston rod moves downward → the rotating frame 9 swings downward → the adjusting roller 10 moves downward → the fabric wrap angle increases → the tension increases. The woven fabric 31 requires high tension (50~200N, adjusted according to weight), and the precise control of the swing angle of the adjusting roller 10 ensures that the fabric surface is flat.

[0045] Furthermore, such as Figure 4 As shown, the fabric feeding mechanism also includes an edge blowing mechanism 12. The edge blowing mechanism 12 includes a slub nozzle 13 for blowing the edge of the knitted fabric 32 flat. The slub nozzle 13 corresponds to the edge position of the knitted fabric 32 and is connected to a high-pressure air source to spray out a flat airflow to smooth the edge curl of the knitted fabric 32, ensuring that the fabric edge is flat when entering the downstream equipment. The edge blowing mechanism 12 can also be attached to the fabric feeding mechanism to directly blow the fabric on the downstream equipment, thereby acting on the knitted fabric 32 during the transportation process of the downstream equipment, assisting the downstream equipment, and preventing the phenomenon of edge curling during the transportation of the fabric in the downstream equipment.

[0046] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
