[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1-5 As shown, a loose fabric guide roller structure for acrylic-polyester fabric includes a guide roller 1, a wrinkle-removing structure 2, a guide rod 22, a connecting sleeve rod 21, a limiting member 3, a limiting rod 31, a shrink-fitting insertion rod 35, and a mounting insertion rod 33. To reduce wrinkles when the acrylic-polyester fabric contacts the guide roller 1, the wrinkle-removing structure 2 is positioned on one side of the guide roller 1. It should be noted that the wrinkle-removing structure 2 includes a guide rod 22 and a connecting sleeve rod 21. Specifically, the guide rod 22 is positioned on one side of the guide roller 1. Specifically, the guide rod 22 is as follows: Figure 1 As shown in the wrinkle-removing structure 2, it has an "n"-shaped design, and the guide rod 22 has rounded corners on all sides. When the acrylic fabric comes into contact with the guide rod 22 and the guide roller 1, the rounded corners of the guide rod 22 will reduce the damage to the acrylic fabric. At the same time, the distance between the guide rod 22 and the guide roller 1 is relatively close, which will greatly reduce the phenomenon of wrinkles when the surface of the guide roller 1 comes into contact with the acrylic fabric. Both sides of the guide rod 22 are connected to the connecting sleeve rod 21, and the connecting sleeve rod 21 and the guide rod 22 are detachably connected by bolts or the like.

[0024] Among the above components, since acrylic polyester fabric is prone to static electricity, the guide roller 1 and guide rod 22 need to be made of anti-static materials, such as carbon fiber reinforced nylon or chrome-plated metal. At the same time, the surfaces of the guide roller 1 and guide rod 22 also need to meet the requirements of high wear resistance. The polyester has high hardness, and the roller surface hardness is recommended to be ≥HRC50.

[0025] During use, the orientation of the acrylic fabric and the guide roller 1 changes due to varying heights. To accommodate these height variations, a limiting member 3 is connected to the end of the connecting sleeve rod 21 away from the guide rod 22. The limiting member 3 includes a limiting rod 31, a shrink-fitting insertion rod 35, and a mounting insertion rod 33. Specifically, the limiting rod 31 is connected to the outer periphery of the connecting sleeve rod 21 away from the guide rod 22. The limiting rod 31 and the outer periphery of the connecting sleeve rod 21 are welded together. Both the limiting rod 31 and the connecting sleeve rod 21 are circular, with the diameter of the limiting rod 31 being larger than the diameter of the connecting sleeve rod 21. Specifically, the connecting sleeve rod 21 has a slot for the shrink-fitting insertion rod 35 to slide into. A shrinkable plug rod 35 is slidably inserted into the inner sleeve 21. The shrinkable plug rod 35 is cylindrical and is inserted into a slot in the connecting sleeve 21. The diameter of the inner cavity of the slot is smaller than the diameter of the open end. The shrinkable plug rod 35 has a convex plate inside the slot that is smaller than the diameter of the inner cavity of the slot. The diameter of the convex plate is larger than the diameter of the open end of the inner cavity of the slot. The end of the shrinkable plug rod 35 away from the connecting sleeve 21 is connected to a mounting plug rod 33. Specifically, multiple circular slots are provided on the vertical plate of the connecting guide roller 1 for the mounting plug rod 33 to be inserted. The circular slots should be arranged in a circumferential array around the center of the guide roller 1 to facilitate adjustment of the position of the guide rod 22, so as to adapt to guide rollers 1 of different heights or acrylic fabrics.

[0026] To facilitate the installation of the connector rod 33, a retraction spring 32 is sleeved on the outside of the retractable connector rod 35, wherein the retraction spring 32 is as follows: Figure 5 The maximum tension design is shown. When the guide roller 1 is installed, the maximum tension contraction spring 32 will insert the mounting plug rod 33 into the circular groove on the vertical plate connecting the guide roller 1. When the position of the guide rod 22 needs to be adjusted, push the mounting plug rod 33 to push the contraction plug rod 35 into the connecting sleeve rod 21, and the installed circular groove can be removed and replaced. One end of the contraction spring 32 is connected to the end of the limit rod 31, and the other end of the contraction spring 32 is connected to the end of the mounting plug rod 33.

[0027] To facilitate the separation of the mounting rod 33 from the circular groove, a push rod 34 is connected to the periphery of the mounting rod 33 located on the end face of the retraction spring 32. Both the push rod 34 and the mounting rod 33 are circular, and the diameter of the push rod 34 is larger than the diameter of the mounting rod 33.

[0028] The guide rod 22 is connected to a sleeve rod 23 at the end located outside the guide roller 1. A bearing 24 is connected to the outside of the sleeve rod 23. The bearing 24 is used to connect the guide rod 22. The guide rod 22 will rotate or be fixed under the action of the bearing 24 and the sleeve rod 23 without being disturbed by the connecting shaft 11.

[0029] The effect achieved by the entire first embodiment is that, during use, the spring 32 contracts as follows: Figure 5 The diagram shows the maximum tension design. When the guide roller 1 is installed, the maximum tension contraction spring 32 will engage the mounting insertion rod 33 with the circular groove on the vertical plate connecting the guide roller 1. To adjust the position of the guide rod 22, push the mounting insertion rod 33 to push the contraction insertion rod 35 into the connecting sleeve rod 21, allowing for the removal and replacement of the mounting groove. Simultaneously, the guide rod 22 has rounded corners on all sides. When the acrylic fabric abuts against the guide rod 22 and the guide roller 1, the guide rod 22... The rounded corner design of guide rod 22 reduces damage to the acrylic fabric. At the same time, the close distance between guide rod 22 and guide roller 1 greatly reduces the occurrence of wrinkles when the surface of guide roller 1 comes into contact with acrylic fabric. In addition, multiple circular grooves are provided on the vertical plate connecting guide roller 1 for inserting the plug rod 33. The circular grooves should be distributed in a circumferential array around the center of guide roller 1 to facilitate adjustment of the position of guide rod 22 and to adapt to guide rollers 1 of different heights or acrylic fabrics.

[0030] Example 2

[0031] like Figure 1-5 As shown, a loose fabric guide roller structure for acrylic-polyester fabric is provided. Both ends of the guide roller 1 are connected to a connecting shaft 11. Both the connecting shaft 11 and the sleeve rod 23 are circular. The connecting shaft 11 and the guide roller 1 are welded together, and the connecting shaft 11 and the guide roller 1 have a through slot.

[0032] The sleeve rod 23 is a circular design with a diameter larger than that of the connecting shaft 11. The sleeve rod 23 and the connecting shaft 11 are sleeved together, so that the sleeve rod 23 and the guide roller 1 are concentrically designed, which is used to adjust the position of the guide rod 22.

[0033] The connecting shaft 11 and the bearing 24 are connected by a sleeve rod 23, so that the connecting shaft 11 and the guide rod 22 can rotate or be fixed without mutual interference.

[0034] The end face of the connecting shaft 11 away from the guide roller 1 is connected to a connecting groove 12. The connecting groove 12 is used to detachably connect with the upright plate through bolts, flanges, etc. to support the connecting shaft 11 and the guide roller 1. The connecting groove 12 and the connecting shaft 11 are connected by a sleeve.

[0035] The effect achieved by the entire second embodiment is that the guide roller 1 and the upright plate are detachably connected by bolts, flanges, etc. through the connecting groove 12 to support the connecting shaft 11 and the guide roller 1. At the same time, the sleeve rod 23 is sleeved with the connecting shaft 11, so that the sleeve rod 23 and the guide roller 1 are designed to be concentric, which is used to adjust the position of the guide rod 22. At this time, the connecting shaft 11 and the bearing 24 are connected through the sleeve rod 23, so that the connecting shaft 11 and the guide rod 22 can rotate or be fixed without mutual interference.

[0036] Working principle: When using the loose fabric guide roller structure of this acrylic-polyester fabric, the guide roller 1 and the upright plate are first detachably connected by bolts, flanges, etc. through the connecting groove 12 to support the connecting shaft 11 and the guide roller 1. At the same time, the sleeve rod 23 is sleeved with the connecting shaft 11, so that the sleeve rod 23 and the guide roller 1 are designed to be concentric, which is used to adjust the position of the guide rod 22. At this time, the connecting shaft 11 and the bearing 24 are connected by the sleeve rod 23, so that the connecting shaft 11 and the guide rod 22 can rotate or be fixed without mutual interference.

[0037] Secondly, when using it, retract spring 32 as follows: Figure 5 The diagram shows the maximum tension design. When the guide roller 1 is installed, the maximum tension contraction spring 32 will engage the mounting plug rod 33 with the circular groove on the vertical plate connecting the guide roller 1. To adjust the position of the guide rod 22, push the mounting plug rod 33 to push the contraction plug rod 35 into the connecting sleeve rod 21, allowing for the removal and replacement of the mounting groove. Simultaneously, the guide rod 22 has rounded corners on all sides. When the acrylic fabric abuts against the guide rod 22 and the guide roller 1, the rounded corners of the guide rod 22 reduce the impact on the fabric. Damage to the acrylic-polyester fabric is minimized. Furthermore, the close distance between the guide rod 22 and the guide roller 1 significantly reduces wrinkles that occur when the surface of the guide roller 1 contacts the acrylic-polyester fabric. Multiple circular grooves are provided on the vertical plate connecting the guide roller 1 for inserting the connecting rod 33. These grooves should be arranged in a circular array around the center of the guide roller 1 to facilitate adjustment of the guide rod 22's position, adapting to guide rollers 1 of different heights or acrylic-polyester fabrics. This ultimately completes the work of the loose guide roller structure for the acrylic-polyester fabric.
