[0034] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Embodiment 1

[0035] like Figures 1 - 7 As shown, the automatic folding curtain machine comprises a frame 1, a moving frame 3 is provided on the frame 1 and reciprocates in a horizontal direction under the drive of a driving device 2, two traction rollers 4 with opposite rotation directions are provided on the moving frame 3, and a material transfer space is formed between the two traction rollers 4, the bamboo curtain passes through the material transfer space, and the bamboo curtain and the traction rollers 4 are in friction contact to guide the bamboo curtain to continuously feed, and at least one traction roller 4 is connected to a rotation driving component 5;

[0036] The rotary drive assembly 5 drives one traction roller 4 to rotate. At this time, since the bamboo curtain contacts another traction roller 4, the other traction roller 4 is forced to rotate as well, thereby achieving the purpose of feeding.

[0037] The rotating drive assembly 5 controls two traction rollers 4 rotating in opposite directions to pull the raw material for transportation, and then the output end of the driving device 2 outputs forward and reverse to control the moving frame 3 to reciprocate on the frame 1, so that the raw material is reciprocated in the frame 1 to form a stack, avoiding the low efficiency of manual folding and improving the folding efficiency.

[0038] The two traction rollers 4 stop rotating when the bamboo curtain is bent, and the driving device 2 moves in the folding direction so that the folding can be neat.

[0039] For example, when the driving device 2 drives the moving frame 3 to move to the left folding position, the two traction rollers 4 stop rotating, and the bamboo curtain is driven by the driving device 2 to fold to the right. When the driving device 2 drives the moving frame 3 to move to the right folding position, the two traction rollers 4 stop rotating, and the bamboo curtain is driven by the driving device 2 to fold to the left. Embodiment 2

[0040] like Figures 1 - 7As shown, the two traction rollers 4 here can be defined as the first traction roller and the second traction roller. Both ends of one of the two traction rollers 4 (the first traction roller) are rotatably connected to the moving frame 3, and the rotation drive assembly 5 drives the traction roller 4 to rotate. The other traction roller 4 (the second traction roller) is connected to the moving frame 3 through a swing adjustment mechanism 7. The swing adjustment mechanism 7 can facilitate the initial material to enter between the two traction rollers 4 and can form the friction force adjustment of the initial material, improving the stability during the conveying process of the initial material. At both ends of the other traction roller 4 (the second traction roller), swing arms 72 are rotatably connected. The swing arms 72 are hinged to the moving frame 3. On the moving frame 3, there is a swing drive 71 for driving the swing arms 72 to swing to adjust the size of the material passing space. By driving the swing arms 72 to adjust the size of the material passing space, the initial material with different thicknesses can be conveyed. The swing drive 71 is any one of a cylinder and an oil cylinder. The rotation drive assembly 5 is any one of a chain drive assembly, a belt drive assembly, and a gear drive assembly. The chain drive assembly is a first driving sprocket, a first driven sprocket, and a first endless chain. The first driving sprocket is fixedly connected to the motor output end of the rotation drive assembly 5, the first driven sprocket is fixedly connected to the traction roller 4, and the first endless chain is drivingly connected between the first driving sprocket and the first driven sprocket. Of course, the belt drive assembly and the gear drive assembly can also meet the usage requirements and are both prior arts.

[0041] The frame 1 and the moving frame 3 are connected through a motion guiding mechanism 6. The motion guiding mechanism 6 is any one of a walking wheel guiding mechanism, a linear guide rail pair, and a linear guide rod pair. For example, the walking wheel guiding mechanism includes a plurality of walking wheels provided on the moving frame 3. On the top of the frame 1, there is a walking wheel rail, and the walking wheels move back and forth on the walking wheel rail. On the frame 1, there is a linkage rod 13. When the moving frames 3 on both sides of the frame 1 move on the frame 1, the linkage rod 13 can make them move in a consistent manner. The driving device 2 is any one of a chain drive device 2, a belt drive device 2, and a gear drive device 2. The chain drive device 2 includes a second driving sprocket, a second driven sprocket, and a second endless chain. The second driving sprocket is fixedly connected to the output end of the driving device 2, the second driven sprocket is fixed on the frame 1, and the second endless chain is drivingly connected between the second driving sprocket and the second driven sprocket. The moving frame 3 is arranged on the second endless chain and is located between the second driving sprocket and the second driven sprocket. One side of the moving frame 3 is fixed with a fixing plate 14, and the moving frame 3 is fixed on the second endless chain through the fixing plate 14. By controlling the forward and reverse reciprocating output of the output end of the driving device 2, the forward and reverse movement of the second endless chain is controlled, so that the moving frame 3 moves horizontally back and forth.

[0042] On the frame 1, there is also a feeding guide roller group 9. The feeding guide roller group 9 and the two traction rollers 4 are arranged in sequence according to the conveying direction. The feeding guide roller group 9 is fixed on one side of the frame 1, facilitating the movement of the starting material along the feeding guide roller group 9 during the initial material conveying, and further ensuring the smoothness during the initial material conveying. The feeding guide roller group 9 includes several feeding rollers that are spaced upward from the bottom on one side of the frame 1. At least one feeding guide roller group 9 is provided with a tension detection sensor. The sensors used in this embodiment are all commercially available.

[0043] On the frame 1, there is also a stacking limit mechanism 10 with a stacking limit state and a cancel stacking limit state. The stacking limit mechanism 10 forms a limit on the stacked material at the bending position of the stacked material. The stacking limit mechanism 10 can be any one of a telescopic limit mechanism and a swinging limit mechanism. On the frame 1, there is a stacked material height detector. The stacking limit mechanism 10 is arranged on the lifting drive assembly 8. The lifting drive assembly 8 performs lifting adjustment according to the stacked material height detected by the stacked material height detector, and the lifting drive assembly 8 can be any one of a screw rod lifting adjustment mechanism, a cylinder or an oil cylinder lifting adjustment mechanism. The stacked material height detector is a photoelectric sensor. Through the detection of the photoelectric sensor, the folding height can be detected. The stacking limit mechanism 10 includes two swinging limit rods 11 whose one ends are respectively hinged on the lifting drive assembly 8. The two swinging limit rods 11 alternately limit the stacked material (that is, one swinging limit rod 11 is in the above-mentioned left folding position during limiting, and the other swinging limit rod 11 is in the above-mentioned right folding position during limiting), so as to stack the stacked material. On the lifting drive assembly 8, there is a power driver 12 connected to drive the swinging limit rod 11 to swing in a plane perpendicular to the vertical direction. By controlling the lifting drive assembly 8, the stacking limit mechanism 10 is controlled to move upward, so that the swinging limit rod 11 can always alternately stack the starting material. The power driver 12 is a cylinder or an oil cylinder.

[0044] The screw rod lifting adjustment mechanism includes two vertically arranged screw rods and a lifting frame body threadedly connected to the screw rods. One end of the swinging limit rod 11 is hinged to the lifting frame body, and the other end of the swinging limit rod 11 is suspended.

[0045] The power driver 12 can drive the swinging limit rod 11 to be in the stacking limit state and the cancel stacking limit state. The cancel stacking limit state can avoid interference with the bamboo curtain. And the stacking limit state can form a limit on the bending position of the bamboo curtain, so that the folding of each layer is in the same position.

[0046] Of course, in order to make the lifting of the lifting drive assembly 8 more smooth, there are rollers on the lifting drive assembly 8 that contact the frame 1 vertically on the frame 1 and travel on the frame 1.

[0047] Working principle: As Figures 1 - 7As shown in the figure, the rotation drive assembly 5 controls two traction rollers 4 with opposite rotation directions to traction the starting material for conveying. Then, through the forward and reverse outputs of the output end of the drive device 2, it controls the moving frame 3 to reciprocate on the frame 1, so that the starting material is reciprocally conveyed in the frame 1 to form a stack, avoiding the low efficiency of manual folding and improving the folding efficiency.
