DETAILED DESCRIPTION
[0024] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] A towel conveying mechanism of a fully automatic towel machine, such as Figure 1 to Figure 2 As shown, it includes a frame, a transmission shaft 1 rotatably connected to the frame, a rotating driving member driving the transmission shaft 1 to rotate, two conveying assemblies 2, and a conveying workbench 5. The rotating driving member is a motor. Each conveying assembly 2 includes a bracket 21 fixed to the frame, at least two upper pulleys 22 mounted on the bracket 21 and rotatable, at least two lower pulleys 23 mounted on the bracket 21 and rotatable, a belt 24 sleeved on the upper pulleys 22 and the lower pulleys 23, a swing arm 25 hinged on the bracket 21, a swing driving member 26 driving the swing arm 25 to swing, and an adjusting wheel 251 mounted on the swing arm 25. The upper pulley 22 and the lower pulley 23 are both synchronous pulleys, and the belt 24 is a synchronous belt 24. The swing arm 25 driving member is a cylinder, the cylinder body is hinged on the bracket 21, and the piston rod is hinged on the swing arm 25. The adjusting wheel 251 presses on the belt 24.
[0026] A conveying working gap 4 is formed between the belt 24 between the two lower pulleys 23 and the conveying worktable 5, and a feeding gap 3 is formed between the belt 24 between the adjusting wheel 251 and one of the lower pulleys 23 and the conveying worktable 5. In the conveying direction, the feeding gap 3 is located upstream of the conveying working gap 4. After the swing drive 26 drives the swing arm 25 to swing toward the conveying worktable 5, the feeding gap 3 decreases, and after the swing drive 26 drives the swing arm 25 to swing away from the conveying worktable 5, the feeding gap 3 increases. In each conveying assembly 2, there is an upper pulley 22 mounted and fixed on the transmission shaft 1. The motor drives the transmission shaft 1 to rotate, which can drive the belts 24 in the two conveying assemblies 2 to move synchronously.
[0027] The swing drive member 26 drives the swing arm 25 to swing away from the conveying workbench 5, thereby enlarging the feed gap 3. After the cut semi-finished towel is fed into the feed gap 3, the swing drive member 26 drives the swing arm 25 to swing toward the conveying workbench 5, thereby reducing the feed gap 3, until the belt 24 presses the semi-finished towel onto the conveying workbench 5 and feeds the semi-finished towel into the conveying working gap 4. The belt 24 in the conveying working gap 4 transports the semi-finished towel forward, thereby achieving the effect of efficiently and accurately receiving the cut semi-finished towel.
[0028] A tensioning arm 27 is hinged on the bracket 21, and a tensioning wheel 271 is installed on the tensioning arm 27. The tensioning wheel 271 presses on the belt 24, and a spring 28 is installed between the tensioning arm 27 and the bracket 21. One end of the spring 28 is fixed on the bracket 21, and the other end is fixed on the tensioning arm 27. The elastic force of the spring 28 drives the tensioning wheel 271 on the tensioning arm 27 to press on the belt 24 to keep the belt 24 tensioned. The elastic force of the spring 28 keeps the belt 24 always at a certain tension.
