DETAILED DESCRIPTION
[0017] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0018] Embodiment 1:
[0019] like Figure 1~Figure 2As shown, the utility model provides a technical solution, a non-woven fabric Z-folding device, including a double-roller conveying device 15 for conveying a non-woven fabric 1, and also includes a bracket 2, a first traction roller 3, a second traction roller 4, a third traction roller 5, a fourth traction roller 6, a pressure rod 7, a pad 8 and a folding triangle plate 9, the first traction roller 3, the second traction roller 4, the third traction roller 5 and the fourth traction roller 6 arranged in parallel are rotatably installed on the bracket 2 in sequence, and the non-woven fabric 1 is sleeved on the upper part of the first traction roller 3, the lower part of the second traction roller 4, the upper part of the third traction roller 5 in sequence. The folding triangle plate 9 is fixedly installed on the bracket 2 and is located between the second traction roller 4 and the third traction roller 5. The pressure rod 7 and the pad 8 are fixedly installed on the bracket 2 and are located between the second traction roller 4 and the third traction roller 5. The pressure rod 7 is tilted upward from the side of the non-woven fabric 1 toward the middle of the non-woven fabric 1, so that the side of the non-woven fabric 1 is folded toward the center. The pad 8 is arranged between the folded parts of the non-woven fabric 1. The folding triangle plate 9 is fixedly installed on the bracket 2 tilted upward and is located between the fourth traction roller 6 and the double-roller conveying device 15. The sharp part of the folding triangle plate 9 is located on the middle section of the non-woven fabric 1.
[0020] The working principle is: the non-woven fabric 1, under the traction of the double-roller conveying device 15, passes through the upper part of the first traction roller 3, the lower part of the second traction roller 4, the upper part of the third traction roller 5, the lower part of the fourth traction roller 6, the folding triangle plate 9 and finally enters between the double-roller conveying device 15. The pressure rod 7 is inclined from the side of the non-woven fabric 1 toward the non-woven fabric 1, and under the interaction of the pad 8, the side of the non-woven fabric 1 is folded toward the center. The non-woven fabric 1 is folded for the first time when entering the third traction roller 5, and the folding direction is folded upward. After that, the folded non-woven fabric 1 is folded for the second time by the folding triangle plate 9 after passing through the folding triangle plate 9, and the folding direction is folded downward, thereby forming a Z-shaped folded non-woven fabric 1. The folding process does not require the operator to perform folding operations. The folded non-woven fabric 1 has a uniform folding specification and size, which improves product quality and greatly reduces the work intensity of the operator. In addition, the degree of automation is high, and the production efficiency is greatly improved.
[0021] In this embodiment, if Figure 1 As shown, the pressure rod 7 and the backing plate 8 are fixedly connected to one end with a sliding block 10, the bracket 2 is also fixedly connected to two connecting shafts 11, the sliding block 10 is key-connected to the connecting shafts 11, and the bracket 2 is also fixedly installed with two telescopic devices 12, the telescopic shafts of the telescopic devices 12 are respectively fixedly connected to the sliding blocks 10 on the two persons, so as to respectively adjust the positions of the pressure rod 7 and the backing plate 8 on the connecting shafts 11. The telescopic device 12 uses a small pneumatic cylinder, and the telescopic device 12 can be used to adjust the positions of the pressure rod 7 and the backing plate 8 on the non-woven fabric 1, and then the width of the first fold of the non-woven fabric 1 can be adjusted, which can meet the requirements of different specifications and has a wider applicability.
[0022] In this embodiment, the connecting shaft 11 is marked with scales to facilitate accurate positioning of the sliding block 10 to determine the folded width of the nonwoven fabric 1 .
[0023] In this embodiment, if Figure 1 As shown, one end of the second traction roller located on the folding side of the nonwoven fabric 1 is arranged inside the side edge of the nonwoven fabric 1. After the nonwoven fabric 1 passes through the second traction roller, the side edge not plane-defined by the second traction roller is more easily folded by the pressure rod 7, making it convenient for the pressure rod 7 to fold the nonwoven fabric 1.
[0024] In this embodiment, if Figure 1 , Figure 2 As shown, a pressing plate 13 is fixedly connected to the bottom of the pad 8, and the pressing plate 13 is parallel to and in contact with the non-woven fabric 1. The pressing plate 13 defines the plane of the non-woven fabric 1, is used to lay the non-woven fabric 1 flat, and also assists in folding the non-woven fabric 1.
[0025] In this embodiment, if Figure 1 , Figure 2 As shown, the folding triangle plate 9 is sleeved with a special-shaped cylinder 14 corresponding to its shape, and the special-shaped cylinder 14 is fixed on the bracket 2, and the non-woven fabric 1 passes through the special-shaped cylinder 14 when passing through the folding triangle plate 9. The special-shaped cylinder 14 is used to gather the non-woven fabric 1 passing through the folding triangle plate 9, so that the non-woven fabric 1 can smoothly enter the double-roller conveying device 15, so that the non-woven fabric 1 enters the double-roller conveying device 15 more flat, and the non-woven fabric 1 is prevented from being folded.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
