Technical Field

[0001] This utility model belongs to the field of roller mechanism technology, and particularly relates to a roller mechanism with adjustable pitch. Background Technology

[0002] The roller mechanism is a cylindrical rotating part in textile machinery that plays a role in feeding, drafting, and outputting. It has the meanings of both roller and shaft. According to its function, it is divided into drafting roller, feeding roller, pressing roller, working roller, etc. Its main function is to draft the yarn and control the yarn tension to make the yarn output uniform.

[0003] However, existing technologies have some problems: existing roller mechanisms are usually fixedly installed on the equipment, and their height needs to be adjusted by adding or removing pads. This method is very inconvenient. Usually, the position is fixed after factory debugging. If adjustment is needed, workers must add rollers to continue the weaving operation, which is very troublesome and has certain limitations. Therefore, we propose a roller mechanism with adjustable spacing. Utility Model Content

[0023] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0024] like Figures 1 to 4 As shown in the figure, an adjustable roller mechanism provided by this utility model includes: a mounting frame 1, on the upper surface of which a first roller shaft 2 and a second roller shaft 3 are disposed, and a driving mechanism 5 is disposed on one side of the mounting frame 1, the driving mechanism 5 being drivenly connected to the first roller shaft 2 and the second roller shaft 3; an adjustment component 4, of which two sets are disposed, the two sets of adjustment components 4 being disposed inside the vertical plates on both sides of the mounting frame 1, and the second roller shaft 3 being located between the two sets of adjustment components 4; and a tensioning component 6, disposed on one side of the mounting frame 1, the tensioning component 6 being drivenly connected to both the driving mechanism 5 and the adjustment component 4.

[0025] Specifically, such as Figure 1 As shown, the first roller shaft 2 remains stationary. The second roller shaft 3 can be adjusted by simultaneously activating the adjustment components 4. Both adjustment components 4 simultaneously drive the two ends of the second roller shaft 3 to slide above the mounting bracket 1, thereby adjusting the distance between the first roller shaft 2 and the second roller shaft 3. This allows for convenient adjustment according to different thicknesses of textile threads, increasing the applicability and functionality of the equipment. Furthermore, the simple and quick adjustment method avoids tedious disassembly and improves work efficiency.

[0026] During the adjustment process, the sliding of the adjusting component 4 will drive the tensioning component 6 to move synchronously. The tensioning component 6 controls the tension of the drive mechanism 5. After the adjustment is completed, the drive mechanism 5 is started, and the drive mechanism 5 can normally provide power to the first roller shaft 2 and the second roller shaft 3, thereby avoiding the problem of unstable fastening and improving the stability during use.

[0027] Furthermore, the drive mechanism 5 includes a drive motor 501 and two sets of rotating seats 504. One end of the output shaft of the drive motor 501 is located at one end of one set of rotating seats 504. One end of each set of rotating seats 504 is provided with a wheel 502, and a transmission belt 503 is provided between the two sets of rotating wheels 502.

[0028] Specifically, such as Figure 1and Figure 3 As shown, when the drive motor 501 is started, the two sets of rotating seats 504 are rotated simultaneously through the cooperation of the two sets of rotating wheels 502 and the transmission belt 503, thereby driving the first roller shaft 2 and the second roller shaft 3 at the same time, thus achieving the effect of convenient use.

[0029] Furthermore, the adjustment component 4 includes an electric push rod 401, which is located on the upper side of the mounting frame 1. A sliding block 402 is provided at one end of the piston rod of the electric push rod 401. Slide grooves 7 are provided on both sides of the mounting frame 1, and the sliding block 402 is slidably installed inside the slide grooves 7.

[0030] Specifically, such as Figures 1 to 3 As shown, the electric push rod 401 is activated to make the sliding block 402 slide up and down inside the slide groove 7, thereby moving the second roller shaft 3 up and down, thus adjusting the distance between the first roller shaft 2 and the second roller shaft 3. This avoids the need for workers to manually add roller shafts and improves the convenience of adjustment.

[0031] Furthermore, guide grooves 8 are provided on both sides of the inner wall of the slide groove 7, and guide blocks 403 are fixedly installed on both sides of the sliding block 402, with the guide blocks 403 slidably installed inside the guide grooves 8.

[0032] Specifically, such as Figure 2 and Figure 3 As shown, during the sliding process of the sliding block 402 in the sliding groove 7, the guide blocks 403 on both sides slide inside the guide groove 8 to limit the sliding block 402, so that the sliding trajectory of the sliding block 402 can only move up and down, thereby achieving stability during adjustment and avoiding deviation.

[0033] Furthermore, the tensioning assembly 6 includes a tensioning wheel 601 and a lead screw 602. A slot 9 is provided on one side of the mounting bracket 1. The lead screw 602 is disposed inside the slot 9. A connecting sleeve 603 is provided on the outer surface of the lead screw 602. The tensioning wheel 601 is disposed at one end of the connecting sleeve 603. One side of the tensioning wheel 601 is in contact with the transmission belt 503.

[0034] Specifically, such as Figure 3 and Figure 4 As shown, by means of the design of the tensioning wheel 601 being in contact with the transmission belt 503, the tensioning wheel 601 controls the tension of the transmission belt 503. When the transmission belt 503 shrinks with the first roller shaft 2 and the second roller shaft 3, and the center distance of the transmission belt 503 cannot be adjusted, the transmission belt 503 will become loose. In this way, the connecting sleeve 603 is driven to slide to one end by the lead screw 602 to tighten the transmission belt 503, so as to avoid the situation of looseness, which would cause the driving effect to fail after adjustment.

[0035] Furthermore, the slot 9 and the guide slot 8 are interconnected so as not to affect the transmission effect. A toothed plate 404 is provided on one side of the guide block 403, and a gear 604 is provided on one end of the lead screw 602. The gear 604 meshes with the toothed plate 404.

[0036] Specifically, such as Figures 1 to 4 As shown, the guide block 403 slides up and down in the guide groove 8, and the toothed plate 404 on one side of the guide block 403 slides accordingly. When the toothed plate 404 slides up and down, it drives the gear 604 to rotate, thereby driving the lead screw 602 to operate and causing the tension wheel 601 to slide. Thus, when the spacing is adjusted, the tension wheel 601 slides at the same time to limit the tightness of the transmission belt 503, avoid loosening, and prevent the roller mechanism from operating normally, thereby improving the stability after adjustment.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
