[0002] The carpet tufting machine is a modern carpet production equipment, which works by weaving yarn into the base fabric through tufting needles under computer control to form a carpet with rich patterns and colors;

[0003] Existing carpet tufting machines lack sufficient flexibility and adaptability, and cannot effectively deal with various deviations that may occur in the carpet fabric during the transmission process. When deviations occur, the carpet tufting machine may not be able to make adjustments in time, resulting in the tufting effect of the carpet being affected, and even causing the carpet to be rolled up, folded or wrinkled. Secondly, when dealing with deviations, existing carpet tufting machines produce excessive friction with the fabric, causing the fabric to wear or tear and damage the carpet material. Utility Model Content

[0004] The utility model provides a deviation correction mechanism for a carpet tufting machine, aiming to solve the problem that the existing carpet tufting machine lacks sufficient flexibility and adaptability and cannot effectively deal with various deviations that may occur in the carpet fabric during the transmission process. When the deviation occurs, the carpet tufting machine may not be able to make adjustments in time, resulting in the tufting effect of the carpet being affected, and even the rolling, folding or wrinkling of the carpet. Secondly, when dealing with the deviation, the existing carpet tufting machine generates excessive friction with the fabric, resulting in the wear or tear of the fabric and damage to the carpet material.

[0005] The utility model is implemented as follows: a deviation correction mechanism for a carpet tufting machine comprises a tufting machine body; a conveying platform arranged on one side of the tufting machine body; a deviation correction device arranged above the conveying platform; wherein the deviation correction device comprises: a group of assembly plates symmetrically arranged on both sides of the upper surface of the conveying platform; two guide rollers rotating between the two assembly plates; a first motor arranged on one side of the assembly plate, the output end of the first motor being fixedly connected with the end key of one of the guide rollers; connecting plates are arranged on the outer sides of the assembly plates; first hydraulic rods are arranged on the bottom sides of the two connecting plates; connecting frames are arranged at the output ends of the two first hydraulic rods; and correction rollers are rotatably matched between the two connecting frames.

[0006] Preferably, the deviation correction device further comprises: a set of fixing frames, two fixing frames are arranged on one side of the conveying platform adjacent to the tufting machine body; second hydraulic rods arranged on the top sides of the two fixing frames; and correction plates arranged on the output ends of the two second hydraulic rods.

[0007] Preferably, the correction plate includes: a plate body connected to the output end of the second hydraulic rod; a plurality of return springs arranged on the bottom side of the plate body, and dampers are arranged in the plurality of return springs; and a same flexible pad is connected to the side of the plurality of return springs away from the plate body.

[0008] Preferably, the two guide rollers are connected via a transmission belt.

[0009] Preferably, the guide roller on the side away from the connecting plate is higher than the other guide roller.

[0010] Preferably, the bottom side of the flexible pad is provided with anti-slip grooves.

[0011] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0012] First, the deviation-correcting device of the device can adjust the height of the connecting frame and the correction roller in real time through the dynamic adjustment of the first hydraulic rod and the second hydraulic rod. This flexibility enables the deviation-correcting device to adapt to the fabric deviation under different circumstances, ensuring the continuity of carpet production and the stability of product quality. The correction roller is adjusted to just above the carpet fabric, effectively limiting the range of movement of the fabric in the vertical direction. When the fabric deviates, it can quickly guide the fabric back to the correct transmission path. At the same time, the correction plate is dynamically adjusted according to the changes in the fabric to maintain close contact with the fabric. This design enables the deviation-correcting device to cope with carpet fabrics of different widths or thicknesses, ensuring effective deviation correction throughout the entire production process.

[0013] Second, the return springs and dampers set on the bottom side of the plate body provide additional buffering and stability for the correction plate. When the carpet fabric contacts the correction plate and generates pressure, the return springs and dampers can absorb and disperse the pressure, reducing the friction and damage of the fabric during the correction process. This design not only improves the smoothness of the correction process, but also helps to extend the service life of the carpet and the correction mechanism. The addition of the flexible pad further enhances the stability and accuracy of the correction mechanism. Its soft and elastic material can better adapt to the surface of the carpet fabric and reduce the possible jamming or scratching during the correction process. At the same time, the flexible pad can also increase the friction between the correction plate and the fabric, ensuring that the fabric can be guided and corrected more accurately.

DETAILED DESCRIPTION

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a carpet tufting machine deviation correction mechanism, such as Figure 1-4 As shown, it includes a tufting machine body 1; a conveying platform 2 arranged on one side of the tufting machine body 1; a correction device arranged above the conveying platform 2; the correction device includes a group of assembly plates 301 symmetrically arranged on both sides of the upper surface of the conveying platform 2; two guide rollers 302 rotating between the two assembly plates 301; a first motor 303 arranged on one side of the assembly plate 301, and the output end of the first motor 303 is fixedly connected with the end key of one of the guide rollers 302; the outer side of the assembly plate 301 is provided with a connecting plate 304; a first hydraulic rod 305 is arranged on the bottom side of the two connecting plates 304; a connecting frame 306 is arranged at the output end of the two first hydraulic rods 305; and a correction roller 307 is rotatably matched between the two connecting frames 306.

[0022] It should be noted that, due to the lack of sufficient flexibility and adaptability of the existing carpet tufting machine, it is unable to effectively deal with various deviations that may occur in the carpet fabric during the transmission process. When a deviation occurs, the carpet tufting machine may not be able to make adjustments in time, resulting in the tufting effect of the carpet being affected, and even the rolling folding or wrinkling of the carpet. Secondly, when dealing with deviations, the existing carpet tufting machine generates excessive friction with the fabric, resulting in the problem of fabric wear or tear causing damage to the carpet material. This solution achieves a high degree of dynamic adjustment and buffer stability. The introduction of the hydraulic rod allows the height of the connecting frame 306 and the correction roller 307 to be adjusted. Real-time adjustment can adapt to the fabric deviation in different situations. The coordinated work of the correction roller 307 and the correction plate 310 can ensure that the fabric is quickly guided back to the correct transmission path when deviation occurs, and the return spring 5 and damper on the bottom side of the plate body 4, as well as the additional flexible pad 6, provide additional buffering and stability for the correction process, effectively reducing the friction and damage of the fabric during the correction process. This comprehensive design improvement not only improves the accuracy and efficiency of the correction process, but also significantly extends the service life of the carpet and the correction device, providing a strong guarantee for the continuity of carpet production and the stability of product quality.

[0023] Specifically, in this embodiment, the scheme mainly includes a tufting machine body 1, a conveying platform 2 and a deviation correction device; the deviation correction device includes an assembly plate 301 and two guide rollers 302; the carpet fabric is placed on the conveying platform 2, and the carpet fabric is pulled from the upper guide roller 302 to the lower guide roller 302. When the first motor 303 is started, it drives the guide roller 302 fixedly connected to the key to rotate, and then drives another guide roller 302 to rotate through the conveying belt 7, thereby realizing continuous transmission of the carpet fabric; during the transmission process, the first hydraulic rod 305 will extend or retract as needed, thereby adjusting the height of the connecting frame 306 and the correction roller 307. The correction roller 307 is adjusted to the top of the carpet fabric, effectively limiting the range of movement of the fabric in the vertical direction. When the fabric deviates, the position adjustment of the correction roller 307 can guide the fabric back to the correct transmission path, thereby realizing the deviation correction function. This dynamic adjustment capability enables the carpet tufting machine deviation correction mechanism to cope with fabric deviations under different circumstances, ensuring the continuity of carpet production and the stability of product quality.

[0024] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the deviation correction device also includes: a group of fixed frames 308, two fixed frames 308 are arranged on one side of the conveying platform 2 adjacent to the tufting machine body 1: a second hydraulic rod 309 arranged on the top side of the two fixed frames 308; and a correction plate 310 arranged at the output end of the two second hydraulic rods 309.

[0025] In this embodiment, when the second hydraulic rods 309 are started, they will extend or retract, driving the correction plate 310 to move in the vertical direction. The position of the correction plate 310 can be adjusted as needed to adapt to carpet fabrics of different widths or thicknesses. During the deviation correction process, the correction plate 310 can serve as an auxiliary guide surface, working in conjunction with the correction roller 307 to guide the carpet fabric back to the correct transmission path. The presence of the correction plate 310 can increase the accuracy and stability of fabric deviation correction, especially when processing wider or thicker fabrics, it can provide better support and guidance. In addition, the telescopic function of the second hydraulic rod 309 also allows the correction plate 310 to be dynamically adjusted according to changes in the fabric, maintaining close contact with the fabric, thereby ensuring that effective deviation correction can be achieved throughout the entire production process.

[0026] In a further preferred embodiment of the present invention, Figure 4 As shown, the correction plate 310 includes: a plate body 4 connected to the output end of the second hydraulic rod 309; a plurality of return springs 5 ​​arranged on the bottom side of the plate body 4, and dampers are arranged in the plurality of return springs 5; and a same flexible pad 6 is connected to the side of the plurality of return springs 5 ​​away from the plate body 4.

[0027] In this embodiment, a plurality of return springs 5 ​​and dampers arranged on the bottom side of the plate body 4 provide additional buffering and stability for the correction plate 310. When the carpet fabric contacts the correction plate 310 and generates pressure, the return springs 5 ​​and the dampers can absorb and disperse the pressure, thereby reducing the friction and damage of the fabric during the correction process. At the same time, the presence of the damper can also reduce the vibration and shaking of the correction plate 310, thereby maintaining its stable position and posture. Finally, a plurality of return springs 5 ​​are connected to the same flexible pad 6 on the side away from the plate body 4. The material of the flexible pad 6 is soft and has a certain degree of elasticity, which can better adapt to the surface of the carpet fabric and reduce the possible jamming or scratching during the correction process. In addition, the flexible pad 6 can also increase the friction between the correction plate 310 and the fabric, thereby further improving the accuracy and stability of the correction.

[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, the guide roller 302 on the side away from the connecting plate 304 is higher than the other guide roller 302 .

[0029] In this embodiment, the guide rollers 302 at different heights are beneficial for the carpet fabric to be more inclined to remain in a taut state when it is subjected to downward force during the conveying process, thereby reducing the occurrence of looseness, which is crucial for maintaining the quality and appearance of the carpet.

[0030] In a further preferred embodiment of the present invention, Figure 4 As shown, the bottom side of the flexible pad 6 is provided with anti-slip grooves.

[0031] In this embodiment, when the carpet fabric contacts the flexible pad 6, the anti-slip pattern can effectively prevent the fabric from sliding or deflecting during the transmission process, thereby ensuring that the fabric can be accurately transmitted along a preset path.

[0032] Working principle: When the device is used, the carpet fabric is placed on the conveying platform 2, and the carpet fabric is pulled from the upper guide roller 302 to the lower guide roller 302. When the first motor 303 is started, it drives the guide roller 302 fixedly connected to it to rotate, and then drives another guide roller 302 to rotate through the conveying belt 7, thereby realizing the continuous conveyance of the carpet fabric;

[0033] During the conveying process, the first hydraulic rod 305 will extend or retract as needed, thereby adjusting the height of the connecting frame 306 and the correction roller 307. The correction roller 307 is adjusted to be just above the carpet fabric, effectively limiting the range of movement of the fabric in the vertical direction. When the fabric deviates, the position adjustment of the correction roller 307 can guide the fabric back to the correct conveying path, thereby realizing the correction function. This dynamic adjustment capability enables the correction mechanism of the carpet tufting machine to cope with fabric deviations in different situations, ensuring the continuity of carpet production and the stability of product quality.

[0034] When the carpet fabric is transmitted to the correcting plate 310, the second hydraulic rods 309 are activated, and they will extend or retract, driving the correcting plate 310 to move in the vertical direction. The position of the correcting plate 310 can be adjusted as needed to adapt to carpet fabrics of different widths or thicknesses. In the process of correcting, the correcting plate 310 can be used as an auxiliary guide surface, working in conjunction with the correcting roller 307 to guide the carpet fabric back to the correct transmission path. The existence of the correcting plate 310 can increase the accuracy and stability of fabric correction, especially when processing wider or thicker fabrics, it can provide better support and guidance. In addition, the telescopic function of the second hydraulic rod 309 also allows the correcting plate 310 to be dynamically adjusted according to the changes in the fabric, maintaining close contact with the fabric, thereby ensuring that effective correction can be achieved throughout the production process;

[0035] The plurality of return springs 5 ​​and dampers arranged on the bottom side of the plate body 4 provide additional buffering and stability for the correction plate 310. When the carpet fabric contacts the correction plate 310 and generates pressure, the return springs 5 ​​and the dampers can absorb and disperse the pressure, thereby reducing the friction and damage of the fabric during the correction process. At the same time, the presence of the damper can also reduce the vibration and shaking of the correction plate 310, thereby maintaining its stable position and posture. Finally, the side of the plurality of return springs 5 ​​away from the plate body 4 is connected to the same flexible pad 6. The material of the flexible pad 6 is soft and has a certain degree of elasticity, which can better adapt to the surface of the carpet fabric and reduce the jamming or scratching that may occur during the correction process. In addition, the flexible pad 6 can also increase the friction between the correction plate 310 and the fabric, thereby further improving the accuracy and stability of the correction.
