Description

Technical Field

[0001] This utility model relates to the field of guide rollers, and more specifically, it relates to a guide roller for a coating device used in processing quick-drying sports nylon fabrics. Background Technology

[0002] Sports nylon fabric is a common material used in the production of sportswear. In order to give the fabric properties such as quick-drying, waterproof and stain-resistant properties, sports nylon fabric is often coated.

[0003] Existing coating equipment generally includes a feeding module, coating head, substrate conveying module, drying module, winding module, and control system. The substrate conveying module uses multiple guide rollers to transport and guide the fabric substrate. To improve coating accuracy, some coating equipment add limiting rings to both sides of the guide rollers. These limiting rings restrict the movement path of the fabric substrate, ensuring it moves along a preset trajectory and preventing positional deviations that could affect the coating effect. In actual production, adjusting the relative positions of the limiting rings is necessary when coating fabric substrates of different sizes. However, adjusting the existing limiting rings is cumbersome, which reduces production efficiency to some extent.

[0004] Based on the above, the purpose of this utility model is to provide a guide roller for a coating device used in processing quick-drying sports nylon fabrics, so as to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a guide roller for a coating device used in processing quick-drying sports nylon fabrics. This invention involves setting sleeves on both sides of the roller body, slidingly connecting limiting rings to the sleeves, setting racks on the limiting rings, and setting drive gears on the roller body to drive the racks to move. Users can adjust the relative positions of the limiting rings on both sides by rotating the drive gears, making the position adjustment of the limiting rings more convenient.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a guide roller for a coating device for processing quick-drying sports nylon fabric, comprising a roller body, sleeves provided on both sides of the roller body, a limiting ring slidably connected to each sleeve, a rack fixedly connected to one end of the limiting ring, the other end of the rack slidably connected to the sleeve, a drive gear meshing with the rack being rotatably connected inside the roller body, and a drive mechanism for driving the drive gear to rotate being provided on the roller body.

[0007] By adopting the above technical solution, the guide roller is rotatably installed in a suitable position in the coating device. When the fabric is conveyed, it is limited by the limiting rings on both sides. When it is necessary to adjust the position of the limiting rings on both sides, the drive mechanism drives the drive gears on both sides to rotate. The drive gears drive the limiting rings on both sides to move through the rack, thereby achieving the effect of quickly adjusting the relative position of the limiting rings on both sides as required.

[0008] The present invention is further configured such that: the driving mechanism includes a worm wheel and a worm shaft, both of which are rotatably connected to the roller body; the worm wheel is fixedly connected to the driving gear; the worm shaft meshes with the worm wheel; a handwheel is provided on the worm shaft, one end of which is fixedly connected to the handwheel; and the other end of the handwheel extends outside the roller body.

[0009] The present invention is further configured such that a synchronizing rod is fixedly connected between the two worm gears, and the threads of the worm wheels and worm gears on both sides are oriented in opposite directions.

[0010] The present invention is further configured such that: a plurality of limiting rods are provided on the limiting ring, one end of which is fixedly connected to the limiting ring, and the other end of the limiting rod is slidably connected to the sleeve.

[0011] The present invention is further configured such that: limiting strips are fixedly connected to both sides of the rack, and the sleeve is provided with limiting grooves for the limiting strips to be inserted and moved.

[0012] In summary, this utility model has the following beneficial effects:

[0013] This invention features sleeves on both sides of the roller body, with slidable connection between the limiting rings and the sleeves. A rack is also installed on the limiting rings. A drive gear that moves the rack and a worm gear mechanism that rotates the drive gear are both installed on the roller body. Users can drive the drive gear through the worm gear mechanism and adjust the relative positions of the limiting rings on both sides as needed, making the position adjustment of the limiting rings more convenient. The self-locking function of the worm gear mechanism also prevents the limiting rings from shifting during operation, resulting in a more stable limiting and guiding effect on the fabric.

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] A guide roller for a coating device used in processing quick-drying sports nylon fabric, such as Figures 1-3 As shown, the roller body 1 is included. Both sides of the roller body 1 are fixedly connected to sleeves 2. Limiting rings 3 are slidably connected to both sleeves 2. The limiting rings are also slidably connected to the outer surface of the roller body. One end of the limiting ring is fixedly connected to the rack 4. The other end of the rack 4 is slidably connected to the sleeve 2. A drive gear 5 that meshes with the rack 4 is rotatably connected inside the roller body 1. The roller body 1 is provided with a drive mechanism that drives the drive gear 5 to rotate.

[0023] Furthermore, the drive mechanism includes a worm wheel 6 and a worm 7, both of which are rotatably connected to the roller body 1. The worm wheel 6 is fixedly connected to the drive gear 5, and the worm 7 meshes with the worm wheel 6. A handwheel 8 is provided on the worm 7, with one end fixedly connected to it, and the other end of the handwheel 8 extends outside the roller body 1.

[0024] Furthermore, a synchronizing rod 9 is fixedly connected between the two worm gears 7, and the threads of the two worm wheels 6 and the worm gears 7 face opposite directions.

[0025] Furthermore, the limiting ring 3 is provided with several limiting rods 10, one end of which is fixedly connected to the limiting rod 10, and the other end of the limiting rod 10 is slidably connected to the sleeve.

[0026] Furthermore, limit strips are fixedly connected to both sides of the rack 4, and the sleeve 2 is provided with limit grooves for the limit strips to be inserted and moved. The design of the limit strips can prevent excessive friction between the rack and the roller body.

[0027] Working principle: The guide roller is rotatably installed in a suitable position on the coating device. Bearings can be installed on the sleeve 2 or the roller body 1, and the roller is rotatably connected to the coating device through the bearings. When the guide roller needs to rotate to transport the fabric, a pulley or toothed ring can be installed on the sleeve or the roller body 1. The guide roller is driven to rotate by an external motor, pulley rotation assembly or gear. When transporting the fabric, the fabric is limited by the limit rings 3 on both sides to prevent the fabric from shifting position during movement.

[0028] When the position of the two limiting rings 3 needs to be adjusted, the handwheel 8 is rotated to drive the worm gear 7 to rotate, which in turn drives the drive gear 5 to rotate through the worm wheel 6. The drive gear 5 drives the two limiting rings 3 to move through the rack 4. The synchronizing rod can make the two worm gears rotate synchronously, so that the two limiting rings move synchronously relative to each other, thereby achieving the effect of quickly adjusting the relative position of the two limiting rings 3 as needed, and making the position adjustment of the limiting rings 3 more convenient. The self-locking function of the worm gear 7 mechanism can also prevent the limiting rings 3 from shifting position during operation, making the limiting rings 3 more stable in limiting and guiding the fabric.

[0029] 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.
