However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0028] The embodiments of this utility model relate to an A-frame roller fixing device, such as... Figures 1 to 4 As shown, it includes:

[0029] In this embodiment, an iron frame 1 is provided in the A-frame roller fixing device; the iron frame 1 mainly serves to support the fabric.

[0030] Wheels 2 are movably connected to both sides of the bottom of the iron frame 1; the wheels 2 serve to roll and transport the fabric.

[0031] Roller 5 is movably connected to the top of the iron frame 1; roller 5 is used to curl the fabric.

[0032] The grinding head friction device 10 is installed on the roller 7 on one side of the roller 5. During the rotation of the roller 5, the friction force is increased and the rotation speed of the roller 5 is controlled. The A-frame roller fixing device in this embodiment can improve stripes and creases. It can adjust the friction force according to the amount of fabric on the A-frame roller to prevent the A-frame roller from repeatedly pulling the fabric back and forth, and can also fix and lock the rolling roller. This solves the technical problem in the prior art that when the imitation suede automotive fabric is directly rolled up with the A-frame during the production process, it will produce irreversible stripes and creases on the surface of the fabric, causing the product to be scrapped.

[0033] To achieve the aforementioned technical effects, the A-frame roller fixing device in this embodiment, as follows: Figures 1 to 4 As shown, the iron frame 1 is an A-shaped iron frame; the two sides of the iron frame 1 are provided with inclined columns 8, and the round wheel 2 is movably connected below the inclined columns 8. A horizontal flat steel 9 is fixed at the intersection of the two inclined columns 8; the outer shell of the bearing seat 19 is fixed on the horizontal flat steel 9.

[0034] To achieve the aforementioned technical effects, the A-frame roller fixing device in this embodiment, as follows: Figures 1 to 4 As shown, the two iron frames 1 are connected and fixed at the same point on the iron frames 1 by square steel 18; a reinforcing rib is fixed at the connection between the inclined column 8 and the square steel 18.

[0035] To achieve the aforementioned technical effects, the A-frame roller fixing device in this embodiment, as follows: Figures 1 to 4 As shown, the rollers 7 at both ends of the roller 5 are fixed in the inner holes of the bearing housing 19; a handwheel 17 is fixed at one end of the roller 5; the outer shell of the bearing housing 19 is fixed to the top of the iron frame 1. The handwheel 17 is used to manually rotate the roller 5, which allows the fabric to be rotated manually.

[0036] To achieve the aforementioned technical effects, the A-frame roller fixing device in this embodiment, as follows: Figures 1 to 4 As shown, the grinding head friction device 10 also includes:

[0037] One end of the fixing shaft 11 is fixed on one side of the iron frame 1; the fixing shaft 11 is used to install and fix the friction grinding head 12;

[0038] Several fixed friction grinding heads 12 are fixed at the other end of the fixed shaft 11;

[0039] Above the fixed friction grinding head 12, on the outside of the bearing housing 19, several rolling friction grinding heads 13 are movably connected to the roller 7 of the drum 5 through the bearing clearance; the rolling friction grinding heads 13 are used to connect with the fixed friction grinding head 12.

[0040] An adjusting bolt 14 is threaded to one end of any one of the rolling friction grinding heads 13. The adjusting bolt 14 presses against the rolling friction grinding head 13, adjusting the friction between the rolling friction grinding head 13 and the fixed friction grinding head 12. When the adjusting bolt 14 moves upward, the friction between the rolling friction grinding head 13 and the fixed friction grinding head 12 increases; when the adjusting bolt 14 moves downward, the friction between the rolling friction grinding head 13 and the fixed friction grinding head 12 decreases. This allows for adjustment of the friction, preventing the A-frame roller from repeatedly pulling the fabric back and forth, and also locking the rolling roller 5 in place. This solves the technical problem in existing technology where, when using the A-frame for direct winding during the production of imitation suede automotive fabric, irreversible stripes and creases are created on the fabric surface, causing product scrap.

[0041] To achieve the aforementioned technical effects, the A-frame roller fixing device in this embodiment, as follows: Figures 1 to 4 As shown, the number of rolling friction grinding heads 13 and fixed friction grinding heads 12 installed can be increased or decreased according to the magnitude of the friction force.

[0042] To achieve the aforementioned technical effects, the A-frame roller fixing device in this embodiment, as follows: Figures 1 to 4 As shown, the rolling friction grinding head 13 is connected to the rolling friction grinding head 13 by key pins or welded together; the fixed friction grinding head 12 is welded together with the fixed friction grinding head 12.

Generally, when the friction patterns of the rolling friction grinding head 13 and the fixed friction grinding head 12 are set in the same direction, the friction force is less; when the friction patterns of the rolling friction grinding head 13 and the fixed friction grinding head 12 are set in opposite directions, the friction force can be adjusted in multiple levels.

[0044] To achieve the aforementioned technical effects, the A-frame roller fixing device in this embodiment, as follows: Figures 1 to 4 As shown, the depth of the friction pattern 15 is between 0.3mm and 1.5mm. Experiments have shown that setting the depth of the friction pattern 15 between 0.3mm and 1.5mm achieves the aforementioned technical effect.
