Description

Technical Field

[0001] The utility model belongs to the technical field of fabric production, and particularly relates to a three-roller fabric roll support device. Background Technique

[0002] A fabric inspection machine is an essential special equipment for inspecting extra-large-width, double-width, and single-width fabrics such as cotton, wool, linen, silk, and chemical fibers before production in the garment industry. During operation, the fabric is unrolled from the unwinding mechanism of the fabric inspection machine, then passes through the inspection table, and is then wound onto the winding mechanism.

[0009] The further setting of the utility model is: Second shaft ends are arranged at both ends of the fabric pressing roll, and a first opening groove in a U shape for the second shaft end to pass through is opened at the upper end of the vertical column.

[0010] The further setting of the utility model is: A first fixed arm is arranged on one side of the vertical column, a first brush roll abutting against the fabric surface is rotatably connected between the two first fixed arms, a second fixed arm is arranged on the side of the vertical column away from the first fixed arm, and a second brush roll abutting against the fabric surface is rotatably connected between the two second fixed arms.

[0011] The further setting of the utility model is: Third shaft ends are arranged at both ends of the first brush roll and the second brush roll, second opening grooves in a U shape for the third shaft end to pass through are opened at both ends of the first fixed arm and the second fixed arm, and the first fixed arm and the second fixed arm extend obliquely upward in the direction away from the vertical column.

[0012] A further setting of the present utility model is that: both the first brush roller and the second brush roller include a roller shaft, a flexible felt surface wrapped around the circumferential side of the roller shaft, and bristles provided on the outer surface of the flexible felt surface. A card slot is provided on the outer wall of the roller shaft, and the extending direction of the card slot is parallel to the extending direction of the roller shaft. Card strips are provided at both side edges of the flexible felt surface and are embedded in the card slot. A damping rubber strip for pressing against the inner wall of the card slot is provided on the side wall of the card strip.

[0013] To sum up, the present utility model has the following beneficial effects:

[0014] 1. Place the cloth roll to be unrolled between the three support rollers. The three support rollers can stably support the cloth roll. Then, the fabric inside the cloth roll is transmitted between the fabric guiding roller and the pressing roller. The first shaft end at the end of the support roller is rotatably connected in the bearing seat. At this time, the three support rollers can be rotatably connected between the two brackets. When the cloth roll is unrolled, rolling friction is generated between the cloth roll and the support rollers. Compared with sliding friction, the friction force of rolling friction is smaller. Therefore, it is beneficial to the smooth unrolling of the cloth roll. At the same time, use the baffle to abut against the end face of the cloth roll to position the position of the cloth roll on the three support rollers. At this time, whether the cloth roll with a paper tube embedded in the center or the cloth roll without a paper tube in the center can be stably unrolled on the three support rollers. Finally, the stable unrolling of different cloth rolls can be realized.

[0015] Among them, the fabric can be pressed against the fabric guiding roller by the pressing roller, which is beneficial to ensuring that the fabric transmitted between the fabric guiding roller and the pressing roller is relatively flat and reducing the possibility of the side of the fabric being folded. At the same time, the pressing force of the pressing roller on the fabric can generate a damping effect on the fabric, which is beneficial to keeping the fabric transmitted between the fabric guiding roller and the pressing roller in a taut state at all times.

[0016] 2. When unrolling cloth rolls of different widths of fabric, the lengths of the cloth rolls will be different. At this time, use the baffle. The sliding sleeve of the connecting rod is sleeved on the first baffle rod. At this time, the baffle can move back and forth along the first baffle rod until the two baffles abut against the end face of the cloth roll. Then, tighten the threaded adjusting shaft so that the lower end of the threaded adjusting shaft presses against the first baffle rod. Finally, the position of the baffle can be adjusted accordingly according to the length of the cloth roll.

[0017] 3. Use the second baffle rod provided at the position between the two brackets and below the first baffle rod. When the cloth roll becomes thinner as it is unrolled, use the second baffle rod to block the side position of the three support rollers to prevent the thinned cloth roll from slipping out of the gap between the first baffle rod and the support rollers.

[0018] 4. The cloth pressing roller is embedded in the first opening groove by using the second shaft end. At this time, the rotational connection of the cloth pressing roller between the two side columns can be realized. At the same time, after moving the cloth pressing roller upward, the cloth pressing roller can be separated from the cloth guiding roller, and the cloth pressing roller can press the fabric on the cloth guiding roller under the action of its own gravity;

[0019] 5. When the fabric is transmitted from the cloth roll, the fabric needs to pass through the first brush roller and the second brush roller before entering the position between the cloth guiding roller and the cloth pressing roller. At this time, the front and back surfaces of the fabric can be surface-cleaned by the first brush roller and the second brush roller, which helps to clean sundries such as lint on the fabric surface;

[0020] 6. The first brush roller and the second brush roller are embedded in the second opening groove by using the third shaft end. Since the first fixed arm and the second fixed arm extend along an inclined upward direction away from the column, at this time, the first brush roller and the second brush roller can be stably embedded in the second opening groove under the action of their own gravity and the extrusion action of the fabric transmission. When the first brush roller and the second brush roller need to be disassembled, only need to lift the first brush roller and the second brush roller upward, and the first brush roller and the second brush roller can be separated from the second opening groove. Finally, it is beneficial to the convenient disassembly and assembly of the first brush roller and the second brush roller;

[0021] 7. The first brush roller and the second brush roller both include a roller shaft, a flexible felt surface wrapped around the circumference of the roller shaft, and bristles arranged on the outer surface of the flexible felt surface. Among them, the flexible felt surface is embedded in the card slot of the roller shaft by using a card strip, and at the same time, it is tightened against the inner wall of the card slot by using a damping rubber strip. At this time, the convenient disassembly and assembly of the flexible felt surface on the roller shaft can be realized, and finally, it is beneficial to the rapid replacement of the flexible felt surface.
