[0022] The content of the present utility model will be further described in detail below in conjunction with specific embodiments:
[0023] like Figure 1 As shown, the utility model is applied to the folding of towel products. First, a transfer device (not shown) transfers a towel to a conveyor. At this time, the towel is in a flat state, and the center of the towel is on the conveyor, and the two sides are on the flaps. Then, the limit plate moves to the top of the towel, moves downward to press the towel, and the two limit plates are both between the two flaps. The flap first moves upward and then inward, so that the two sides of the towel are first folded upward and then inward. Finally, the two limit plates move slightly upward and toward each other, and the folded towel is conveyed by the conveyor and separated from the limit plates and transferred to the next process. Specifically, a towel folding device includes a conveyor 1, a folding device 2 arranged on both sides of the conveyor 1, and a limit device 3 arranged above the conveyor 1. The conveyor 1 includes a plurality of conveyor belts 11 arranged in parallel, and the plurality of conveyor belts 11 are spaced apart from each other and move synchronously.
[0024] The folding device 2 includes a flap 21, which is mounted on the side of the conveyor 1 and driven by a first cylinder 22 with a vertical direction. The piston end of the first cylinder 22 moves upward, and its piston end is connected to a second cylinder 23 with a horizontal direction. The flap 21 is connected to the second cylinder 23 and can move closer to or farther from the conveyor 1 under the drive of the second cylinder 23. In this embodiment, the folding devices 2 on both sides are arranged symmetrically; the upper end surfaces of the flaps 21 are horizontally arranged, and the sides of the two flaps 21 that approach each other are parallel to each other and parallel to the conveying direction of the conveyor 1.
[0025] The limiting device 3 includes two limiting plates 31, which are symmetrically arranged in the conveying direction of the conveyor 1. The limiting plates 31 can be plate-shaped, and the sides of the two limiting plates 31 that are away from each other are parallel to each other and parallel to the conveying direction of the conveyor 1. The limiting plates 31 can also be rod-shaped. The limiting plates 31 are connected to a third cylinder 32 at the end of the limiting plate 31 near the upward end of the conveying direction of the conveyor 1. The third cylinder 32 can drive the limiting plates 31 to move in the vertical direction. The third cylinder 32 is connected to a first drive device 33. The first drive device 33 is simultaneously connected to the two third cylinders 32 and can drive the two limiting plates 31 to move simultaneously in opposite or opposite directions by driving the two third cylinders 32.
[0026] Among them, the first driving device 33 includes a first bracket 331. A first motor 332 and two pulleys 333 arranged on the same horizontal plane are connected to the first bracket 331. A belt 334 is connected to the two pulleys 333. The first motor 332 is connected to one of the pulleys 333, and thus can drive the belt 334 to rotate. Two third cylinders 32 are respectively connected to the belt 334 above the pulley 333 and the belt 334 below the pulley 333. To further ensure the stability of the movement of the two third cylinders 32 and the two limit plates 31, two horizontally arranged guide rails 335 can be connected to the first bracket 331. The guide rails 335 can be arranged in two parallel lines. The third cylinder 32 is connected with a slider 336 that cooperates with the guide rail 335. When the first motor 332 drives the third cylinder 32 to move, the third cylinder 32 moves on the slide rail through the slider 336.
[0027] As Figure 1 and Figure 2 shown, when the towel is folded, first, other transfer devices transfer the towel to the conveyor 1. At this time, the towel is placed flat, and both sides of the towel are placed above the turning plates 21. The first motor 332 is started, and the belt drives the two third cylinders 32 to move synchronously and towards each other. Then, the two limit plates 31 move synchronously and towards each other and move to directly above the towel. Then, under the drive of the third cylinder 32, the limit plates 31 move downward to press against the towel. At this time, the two limit plates 31 are between the two turning plates 21, and in the horizontal direction, the distance between the edge of the limit plate 31 and the edge of the turning plate 21 is at least the thickness of one towel. Of course, the setting of the distance cannot be too large either. If the distance is too large, the limit plate 31 will not play a role in restricting the crease during folding. After that, under the drive of the first cylinder 22, the turning plates 21 move upward, and under the drive of the second cylinder 23, the turning plates 21 on both sides move towards each other, causing the towel to fold upward first and then inward to complete the folding of the towel. Among them, when the towel folds upward, it needs to abut against the turning plates 21. Therefore, the distance that the first cylinder 22 drives to move should not be too large, otherwise it will exceed the edge of the towel and cause it to be unable to fold. After folding, the turning plates 21 are reset under the drive of the first cylinder 22 and the second cylinder 23. Then, under the drive of the conveyor 1, the towel disengages from the limit plates 31 and is transported to the next process.
[0028] Among them, after the towel is folded, the limit plates 31 are equivalent to being wrapped inside the towel. Therefore, before the towel is transported, the limit plates 31 move slightly towards each other under the drive of the first motor 332, and at the same time move slightly upward under the drive of the third cylinder 32, so that the folded towel is in a relaxed state, facilitating the towel to disengage from the limit plates 31. In addition, the conveyor 1 being provided with multiple conveyor belts 11 can increase the friction on the towel and prevent the towel from slipping during transportation.
[0029] The above embodiments are only used to illustrate the technical concept and characteristics of the present utility model. The purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it accordingly, and it should not be used to limit the protection scope of the present utility model.
