Description

Technical Field

[0001] This application belongs to the field of textile equipment technology, and in particular relates to a fabric feeding mechanism for setting polyester fabric. Background Technology

[0002] In the production of polyester fabrics, the setting process is a core step in improving the fabric's dimensional stability, surface smoothness, and mechanical properties. However, existing setting equipment has significant deficiencies in the tension adjustment function of its fabric feeding mechanism, directly affecting the setting effect and the quality of the finished product.

[0003] Traditional fabric feeding mechanisms often employ fixed pressure roller assemblies or manually adjustable adjusting rollers, with tension regulation achieved by changing the height of the adjusting roller through the depth of screwing in a threaded rod. However, such mechanical adjustments rely on human experience and often use a single adjustment mode, failing to respond in real time to dynamic tension changes in the fabric caused by elastic fluctuations, humidity variations, or equipment vibrations during transport. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this application is to provide a fabric feeding mechanism for setting polyester fabrics, which can solve the above-mentioned problems.

[0005] The purpose of this application is to provide a fabric feeding mechanism for shaping polyester fabric, including a frame, a guiding mechanism, an adjusting device, and a control device;

[0006] The guiding mechanism is mounted on the frame and includes multiple guide rollers for conveying the fabric;

[0007] The adjustment device is located on the frame and on one side of the shaping device, and is used to fix the fabric.

[0008] The control device is connected to the guiding mechanism and the adjusting device to achieve coordinated control.

[0009] The aforementioned polyester fabric feeding mechanism for setting can compensate for tension fluctuations caused by elastic deformation and equipment vibration during fabric conveying in real time through the coordinated linkage of the control and adjustment devices. Compared with traditional fixed pressure rollers or manual threaded rod adjustment modes, the adjustment device of this application avoids the response lag problem of a single mechanical structure. Simultaneously, the multi-guide roller layout in the guiding mechanism forms a closed-loop feedback with the control device, achieving tension equalization in the pretreatment stage before the setting chamber. The control device here is the same as that used in traditional textile equipment and will not be described in detail here.

[0010] Furthermore, the adjusting device includes:

[0011] drive;

[0012] Two pairs of rotatable rods, with a first roller installed between one pair of rods and a second roller installed between the other pair of rods;

[0013] The driver drives two pairs of rods to rotate, and the two pairs of rods are arranged in a cross pattern through a gear meshing structure.

[0014] The actuator synchronously drives two pairs of rods to rotate via a gear meshing structure, causing the first and second rollers to move symmetrically up and down. The gear meshing ensures that the bidirectional tensile force generated during roller spacing adjustment is evenly distributed across the fabric, preventing fabric shift caused by stress concentration on one side. The cross-distribution of the two pairs of rods forms a support frame, helping to more stably fix the fabric and ensuring a more accurate fabric path as it passes the adjustment device. Simultaneously, the cross-distribution creates an asymmetrical height difference between the first and second rollers in the vertical plane, dynamically adjusting the wrap angle of the fabric path. Furthermore, the actuator here is a motor, which can adjust the fabric position or tension by adjusting the angle between the two rods.

[0015] Furthermore: the adjustment device also includes two sets of telescopic adjustment components, which are respectively connected to two pairs of rods. Each set of telescopic adjustment components includes:

[0016] The internal connector is pivotally connected to the rod body at one end.

[0017] External component, connected to the frame pivot.

[0018] When both rods rotate simultaneously, the outer and inner connectors move and extend relative to each other, thus buffering the adjustment process and preventing instability caused by rapid adjustments, ensuring the accuracy of angle adjustment. Simultaneously, the installation of the telescopic adjustment component creates a frictional damping effect through the axial relative displacement between the inner and outer connectors, dissipating most of the heat energy from the instantaneous impact of the driver and effectively suppressing fabric shaking caused by sudden acceleration changes in the adjusting roller.

[0019] Furthermore, the external component includes:

[0020] The outer shell has an internal cavity;

[0021] The inner sleeve is placed inside the cavity;

[0022] The first sliding assembly includes a first sliding piece and a second sliding piece located in the inner sleeve body and connected by a first elastic body.

[0023] It also includes a second elastic body, which connects the second slide plate and the inner sleeve.

[0024] When the angle between the two rods changes, the inner connector drives the first sliding assembly to move. This means the first and second sliders move within the inner sleeve, compressing the first and second elastic bodies. The first spring is compressed first, absorbing the initial impact of the rod rotation. As the displacement continues to increase, the second spring intervenes to provide secondary cushioning. The synergistic effect of the two springs decomposes the instantaneous impact force into multi-stage attenuation. Here, both the first and second elastic bodies are springs; their cooperation buffers the adjustment process of the two rods.

[0025] Furthermore, the internal connector includes:

[0026] The second sliding assembly includes a third sliding piece that slides within the inner sleeve, a fourth sliding piece that slides within the cavity, and a guide rod connecting the two.

[0027] The linkage assembly includes a first connecting arm that connects the third sliding plate and the first sliding plate, and a second connecting arm that extends out of the outer casing.

[0028] The second connecting arm is pivotally connected to the rod body.

[0029] The second sliding assembly works in conjunction with the linkage assembly. The guide rod is used to limit the direction of extension and retraction and to provide auxiliary guidance. The inner housing is provided with multiple through holes that are compatible with the guide rod. At the same time, a first connecting arm is provided, with one end connected to the third sliding plate and the other end connected to the first sliding plate. One end of the second connecting arm is connected to the fourth sliding plate and the other end extends out of the outer housing. Thus, the movement of the second connecting arm can drive the movement of the first connecting arm, which in turn drives the movement of the first and second sliding plates inside the inner housing, completing the buffering work of extension and retraction.

[0030] Furthermore, the internal connector also includes:

[0031] The first disc spring is located between the first connecting arm and the third slider;

[0032] The second disc spring is located between the second connecting arm and the fourth sliding plate;

[0033] Among them, the outer diameter of the first disc spring is smaller than the inner diameter of the inner sleeve, and the outer diameter of the second disc spring is smaller than the inner diameter of the cavity.

[0034] In this application, since both the first and second elastic bodies are springs, they are prone to jamming during repeated use and extension. In severe cases, this can cause the connected structure to become stuck, making adjustment impossible. However, this application installs a first disc spring and a second disc spring, both of which are elastic and can continue to provide a certain distance of displacement to the stuck structure, i.e., the first slide and the second slide, thereby avoiding damage to the overall structure.

[0035] Furthermore, a linear bearing is also installed on the inner sleeve, and the guide rod passes through the linear bearing and slides in fit.

[0036] The linear bearing is installed in the through hole, and the inner wall of the linear bearing forms a sliding connection with the guide rod, which significantly reduces the frictional resistance when the guide rod slides and reduces jamming.

[0037] The beneficial effects of this application are:

[0038] 1. Through the coordinated linkage of the control device and the adjustment device, the tension fluctuation caused by elastic deformation and equipment vibration during the fabric conveying process can be compensated in real time. Compared with the traditional fixed pressure roller or manual threaded rod adjustment mode, the adjustment device of this application avoids the response lag problem of a single mechanical structure.

[0039] 2. The multi-guide roller layout in the guiding mechanism and the control device form a closed-loop feedback, which completes tension equalization in the pretreatment stage before the shaping chamber;

[0040] 3. By installing the telescopic adjustment component, the axial relative displacement between the inner and outer components will generate a frictional damping effect, which can dissipate most of the heat energy of the instantaneous impact force of the driver and effectively suppress the fabric shaking phenomenon caused by the sudden acceleration of the adjustment roller.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0047] The fabric feeding mechanism for setting polyester fabric provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0048] Example 1:

[0049] like Figure 1 and Figure 2 As shown, this application embodiment provides a fabric feeding mechanism for shaping polyester fabric, including a frame 100, a guiding mechanism 200, an adjusting device 300, and a control device;

[0050] The guiding mechanism 200 is mounted on the frame 100 and includes a plurality of guide rollers 210 for conveying the fabric;

[0051] The adjusting device 300 is located on the frame 100 and on one side of the shaping device, and is used to fix the fabric.

[0052] The control device is connected to the guide mechanism 200 and the adjustment device 300 to achieve coordinated control.

[0053] In some embodiments of this application, such as Figure 1As shown, the above-mentioned polyester fabric setting feeding mechanism, through the coordinated linkage of the control device and the adjustment device 300, can compensate in real time for tension fluctuations caused by elastic deformation and equipment vibration during fabric conveying. Compared with the traditional fixed pressure roller or manual threaded rod adjustment mode, the adjustment device 300 of this application avoids the response lag problem of a single mechanical structure. At the same time, the multi-guide roller 210 layout in the guide mechanism 200 forms a closed-loop feedback with the control device, completing tension equalization in the pretreatment stage before the setting chamber. The control device here is the control device used in traditional textile equipment, which will not be described in detail here.

[0054] Example 2:

[0055] This application provides a fabric feeding mechanism for shaping polyester fabric. In addition to the above-mentioned technical features, the fabric feeding mechanism for shaping polyester fabric in this application also includes the following technical features.

[0056] like Figure 1 and Figure 2 As shown, the adjustment device 300 includes:

[0057] Drive 310;

[0058] Two pairs of rotatable rods 320, one pair of rods 320 with a first roller 330 installed between them, and the other pair of rods 320 with a second roller 340 installed between them;

[0059] The driver 310 drives two pairs of rods 320 to rotate, and the two pairs of rods 320 are arranged in a cross pattern through a gear meshing structure.

[0060] In this embodiment, the driver 310 synchronously drives two pairs of rods 320 to rotate via a gear meshing structure, causing the first roller 330 and the second roller 340 to form a symmetrical lifting motion. The gear meshing ensures that the bidirectional tensile force generated during the adjustment of the distance between the two rollers is evenly applied to both sides of the fabric, avoiding fabric shifting caused by stress concentration on one side. The cross-distribution of the two pairs of rods 320 forms a support frame, which helps to more stably fix the fabric and ensures a more accurate path for the fabric when passing through the adjustment device 300. Simultaneously, the cross-distribution creates an asymmetrical height difference between the first roller 330 and the second roller 340 in the vertical plane, dynamically adjusting the wrap angle of the fabric's travel path. Furthermore, the driver 310 here is a motor, which can adjust the position or tension of the fabric by adjusting the angle between the two rods 320.

[0061] Furthermore, the adjusting device 300 also includes two sets of telescopic adjusting components 350, which are respectively connected to two pairs of rods 320. Each set of telescopic adjusting components 350 includes:

[0062] The inner connector 400 is pivotally connected at one end to the rod body 320;

[0063] External component 500 is pivotally connected to frame 100.

[0064] When both rods 320 rotate simultaneously, the outer connector 500 and the inner connector 400 move and extend relative to each other, thus buffering the adjustment process of the rods 320, avoiding instability caused by rapid adjustment, and ensuring the accuracy of angle adjustment. At the same time, through the installation of the telescopic adjustment component, the axial relative displacement between the inner connector 400 and the outer connector 500 will generate a frictional damping effect, which can dissipate most of the heat energy of the instantaneous impact force of the driver 310, effectively suppressing the fabric shaking phenomenon caused by the sudden acceleration of the adjustment roller.

[0065] Example 3:

[0066] This application provides a fabric feeding mechanism for shaping polyester fabric. In addition to the above-mentioned technical features, the fabric feeding mechanism for shaping polyester fabric in this application also includes the following technical features.

[0067] like Figure 3 As shown, the external component 500 includes:

[0068] The outer casing 510 has an internal cavity 511;

[0069] The inner sleeve 520 is placed inside the cavity 511;

[0070] The first sliding assembly includes a first sliding piece 530 and a second sliding piece 540 that are slidably installed in the inner sleeve 520, and the two are connected by a first elastic body 550.

[0071] It also includes a second elastic body 560, which connects the second slide plate 540 and the inner sleeve 520.

[0072] In this embodiment, when the included angle between the two rods 320 changes, the inner connector 400 drives the first sliding assembly to move. That is, the first and second sliders move within the inner sleeve 520, thereby compressing the first elastic body 550 and the second elastic body 560. The first spring is preferentially compressed, absorbing the initial impact of the rod 320's rotation. As the displacement continues to increase, the second spring intervenes to form a secondary buffer. The synergistic effect of the two springs decomposes the instantaneous impact force into multi-stage attenuation. Here, both the first elastic body 550 and the second elastic body 560 are springs; the cooperation of the two elastic bodies buffers the adjustment process of the two rods 320.

[0073] Example 4:

[0074] This application provides a fabric feeding mechanism for shaping polyester fabric. In addition to the above-mentioned technical features, the fabric feeding mechanism for shaping polyester fabric in this application also includes the following technical features.

[0075] like Figure 3 As shown, the internal connector 400 includes:

[0076] The second sliding assembly includes a third sliding piece 410 that slides within the inner sleeve 520, a fourth sliding piece 420 that slides within the cavity 511, and a guide rod 430 that connects the two.

[0077] The linkage assembly includes a first connecting arm 440 connecting the third sliding plate 410 and the first sliding plate 530, and a second connecting arm 450 extending outside the outer casing 510.

[0078] The second connecting arm 450 is pivotally connected to the rod 320.

[0079] In this embodiment, the second sliding component works in conjunction with the linkage component. The guide rod 430 is used to limit the direction of extension and retraction and to provide auxiliary guidance. The inner housing is provided with multiple through holes that are adapted to the guide rod 430. At the same time, by providing a first connecting arm 440, one end of the first connecting arm 440 is connected to the third sliding plate 410 and the other end is connected to the first sliding plate 530. One end of the second connecting arm 450 is connected to the fourth sliding plate 420 and the other end extends to the outside of the outer housing 510. Thus, the movement of the second connecting arm 450 can drive the first connecting arm 440 to move, thereby driving the first sliding plate 530 and the second sliding plate 540 inside the inner housing to move, completing the buffering work of extension and retraction.

[0080] Furthermore, a linear bearing 570 is also installed on the inner sleeve 520, and the guide rod 430 passes through the linear bearing 570 and slides in fit.

[0081] The linear bearing 570 is installed in the through hole, and the inner wall of the linear bearing 570 forms a sliding connection with the guide rod 430, which significantly reduces the frictional resistance when the guide rod 430 slides and reduces the jamming phenomenon.

[0082] Example 5:

[0083] This application provides a fabric feeding mechanism for shaping polyester fabric. In addition to the above-mentioned technical features, the fabric feeding mechanism for shaping polyester fabric in this application also includes the following technical features.

[0084] like Figure 3 As shown, the internal connector 400 also includes:

[0085] The first disc spring 460 is located between the first connecting arm 440 and the third slider 410;

[0086] The second disc spring 470 is located between the second connecting arm 450 and the fourth slider 420;

[0087] Among them, the outer diameter of the first disc spring 460 is smaller than the inner diameter of the inner sleeve 520, and the outer diameter of the second disc spring 470 is smaller than the inner diameter of the cavity 511.

[0088] In this embodiment, since both the first elastic body 550 and the second elastic body 560 are springs, they are prone to jamming during repeated use and extension. In severe cases, this can cause the connected structure to become stuck, making adjustment impossible. However, this application installs the first disc spring 460 and the second disc spring 470, both of which are elastic and can continue to provide a certain distance of displacement to the stuck structure, i.e., the first slider 530 and the second slider, thereby avoiding damage to the overall structure.
