Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0029] In one embodiment of this utility model, such as Figure 1-5As shown, a fabric opening and tearing device includes a frame 1, an opening assembly 2, a tearing assembly 3, and a fabric guide assembly 4. The opening assembly 2, the tearing assembly 3, and the fabric guide assembly 4 are respectively installed on the frame 1. The opening assembly 2 is located below the front side of the tearing assembly 3 and is used for opening the fabric width. The fabric guide assembly 4 is located above the rear side of the tearing assembly 3. The tearing assembly 3 includes a tearing element 31, a rotating rod 32, and a first driving part 33. The rotating rod 32 is rotatably installed on the frame 1. The tearing element 31 is installed on the rotating rod 32. The tearing element 31 has a tearing part 34, which is a raised arc structure and can protrude from the front side of the opening assembly 2. The first driving part 33 is used to drive the rotating rod 32 to rotate.In this embodiment, a fabric conveying device is provided on the front side of the frame 1, and a fabric traction device is provided on the rear side of the frame 1. Before opening and tearing, the rolled, twisted, wrinkled, or edge-sewn fabric needs to be sequentially arranged along the fabric conveying device, the opening and tearing device, and the fabric traction device. During operation, if the fabric is only rolled, twisted, or wrinkled and its two edges are not sewn together, tearing is not required. At this time, the first driving unit 33 drives the rotating rod 32 to rotate, and the rotating rod 32 drives the tearing piece 31 to swing backward, so that it is stored in the opening assembly 2 and the guide fabric. Between components 4, i.e., the tearing edge component 3 is inactive, then the fabric conveying device 1 begins to convey the fabric and the fabric traction device pulls the fabric. When the fabric passes the opening component 2, the opening component 2 opens the fabric, causing the rolled, twisted, or wrinkled fabric to spread out and flatten. The fabric is then smoothly conveyed to the fabric traction device at the rear via the fabric guide component 4. If the two sides of the fabric are sewn, tearing is required. At this time, the rotating rod 32 rotates, driving the tearing edge component 31 to rotate. The tearing edge portion 34 of the tearing edge component 31 swings forward until the tearing edge portion 34... 4 protrudes from the front side of the opening assembly 2. Then, the fabric conveying device 1 starts to convey the fabric, and the fabric traction device pulls the fabric. When the fabric passes through the opening assembly 2, the fabric with sewn edges becomes initially flat after the opening, making it easier for the tearing edge part 34 of the subsequent tearing edge part 31 to enter the sewn tearing point. When the fabric passes through the tearing edge part 3, the protruding arc-shaped tearing edge part 34 can tear the cylindrical fabric with the two sides sewn together, becoming flat fabric. After the fabric passes through the opening and tearing edge, the fabric guiding assembly 4 guides and conveys the fabric, so that the fabric can be smoothly conveyed and transitioned to the fabric traction device on the rear side. This application utilizes a frame 1, an opening assembly 2, a tearing assembly 3, a tearing piece 31, a rotating rod 32, a first driving part 33, a tearing part 34, and a guide assembly 4. During the fabric conveying process, the opening assembly 2 opens the fabric to make it flat, and the tearing part 34 with a raised arc structure tears the cylindrical fabric whose two edges are sewn together. The tearing efficiency is high. When tearing is not needed, the tearing piece 31 can be swung and stored to reduce space occupation. This achieves the purpose of both opening and tearing without the need for two separate machines for opening and tearing, which is convenient, fast, and has high production efficiency.

[0030] like Figure 1-3As shown, the tear-off piece 31 includes a first connecting segment 311, a second connecting segment 312, a third connecting segment 313, a fourth connecting segment 314, a fifth connecting segment 315, and a reinforcing segment 316. The two ends of the fifth connecting segment 315 are respectively connected to one end of the two fourth connecting segments 314, the other ends of the two fourth connecting segments 314 are respectively connected to one end of the two third connecting segments 313, the other ends of the two third connecting segments 313 are respectively connected to one end of the two second connecting segments 312, the other ends of the two second connecting segments 312 are respectively connected to one end of the two first connecting segments 311, the other ends of the two first connecting segments 311 are respectively connected to the rotating rod 32, and the two ends of the reinforcing segment 316 are respectively connected to the two fourth connecting segments 314. In this embodiment, the fifth connecting segment 315 is an arc structure. The fifth connecting segment 315 and the two fourth connecting segments 314 constitute the tear edge portion 34. The reinforcing segment 316 plays a reinforcing role, which helps to improve the structural stability of the tear edge portion 34 and make it less prone to deformation. Specifically, one end of the third connecting segment 313 and the second connecting segment 312 is an obtuse angle connection structure, and the other end of the second connecting segment 312 and the first connecting segment 311 is an obtuse angle connection structure. The two obtuse angle structures make the tear edge portion 34 tilted upward when tearing, which facilitates tearing the fabric. Preferably, the first connecting segment 311, the second connecting segment 312, the third connecting segment 313, the fourth connecting segment 314, the fifth connecting segment 315 and the reinforcing segment 316 are all round rod structures to prevent the sharp corners from scratching the fabric and to facilitate the fabric to slide through.

[0031] like Figure 1-2 and Figure 5 As shown, the tearing edge assembly 3 further includes a drive plate 35 and a connecting rod 36. One end of the drive plate 35 is mounted on the end of the rotating rod 32, and one end of the connecting rod 36 is connected to the other end of the drive plate 35. The other end of the connecting rod 36 is rotatably mounted on the output end of the first drive unit 33, which is hinged to the inner side of the frame 1. In this embodiment, the first drive unit 33 is a cylinder, and a hinge seat is provided on the top of the first drive unit 33. The first drive unit 33 is hinged to the inner side of the frame 1 through the hinge seat. During operation, the output end of the first drive unit 33 extends and retracts, thereby driving the rotating rod 32 to rotate through the connecting rod 36 and the drive plate 35. During the extension and retraction process, the first drive unit 33 will adaptively swing and adjust its position to prevent jamming.

[0032] like Figure 1-2 and Figure 4As shown, the flapping assembly 2 includes a flapping rod 21, a main rod 22, mounting blocks 24, height blocks 25, mounting rods 26, and a second drive unit 27. The two ends of the main rod 22 are respectively mounted on the two mounting blocks 24, and the two ends of the flapping rod 21 are respectively mounted on the two mounting blocks 24. The two flapping rods 21 are located on both sides of the main rod 22, and the flapping rods 21 are bent rod structures. The mounting rods 26 are mounted on the frame 1, and the two height blocks 25 are mounted on the mounting rods 26. The mounting blocks 24 are rotatably mounted on the height blocks 25. The second drive unit 27 can be used to drive the mounting blocks 24 to rotate. In this embodiment, there are two of each of the following: the flapping rod 21, the mounting block 24, and the height block 25. The mounting rod 26 is installed on the front side of the frame 1, and each mounting rod 26 has two height blocks 25 mounted on it. The two ends of the main rod 22 are respectively installed in the middle of the mounting block 24. The two ends of the two flapping rods 21 are respectively installed at the ends of the two mounting blocks 24. The two flapping rods 21 are located on both sides of the main rod 22. The two flapping rods 21 are curved rod structures with a bent and convex shape in the middle. The two mounting blocks 2 are installed on the inner side of the two height blocks 25. The second drive... The moving part 27 is installed on the outside of the left height block 25. The second driving part 27 is a motor. The output end of the second driving part 27 is connected to the mounting block 24 on the left. When working, the second driving part 27 drives the mounting block 24 to rotate, thereby adjusting the protruding position of the opening rod 21 on the front side of the frame 1, which facilitates subsequent opening. When the fabric passes the opening rod 21, the outer protrusion of the opening rod 21 abuts against the middle of the fabric, and the two ends of the fabric move to both sides under the action of the bending structure on both sides, so that the rolled, twisted or wrinkled fabric is spread out and laid flat, which is convenient and quick.

[0033] like Figure 1-2 and Figure 4 As shown, the flapping assembly 2 also includes a reinforcing rod 23, one end of which is connected to the main rod 22, and the other end of which is connected to the flapping rod 21. In this embodiment, there are two reinforcing rods 23. One end of each reinforcing rod 23 is connected to both sides of the main rod 22, and the other end of each reinforcing rod 23 is connected to the inner side of the bend of the flapping rod 21. This helps to improve the structural stability of the components consisting of the flapping rod 21, the main rod 22, and the reinforcing block 24, making them less prone to deformation.

[0034] like Figure 1-2As shown, the flap assembly 2 further includes a third drive unit. The mounting rod 26 is rotatably mounted on the frame 1, and the third drive unit can be used to drive the mounting rod 26 to rotate. In this embodiment, the third drive unit includes a motor, a first gear, and a second gear. The motor is mounted on the left side of the frame 1, and the first gear is mounted on the output end of the motor. The second gear is mounted on the left end of the mounting rod 26, and the second gear meshes with the first gear. Through the motor and gear structure, the mounting rod 26 can be driven to rotate, thereby adjusting the forward protrusion position of the flap rod 21, giving the flap rod 21 a greater range of adjustment.

[0035] like Figure 1-2 As shown, the fabric guiding assembly 4 includes a first guide roller 41, a second guide roller 42, and a third guide roller 43. The first guide roller 41, the second guide roller 42, and the third guide roller 43 are rotatably mounted on the frame 1. The first guide roller 41 is located below the front side of the second guide roller 42, and the third guide roller 43 is located above the rear side of the second guide roller 42. In this embodiment, the first guide roller 41, the second guide roller 42, and the third guide roller 43 are all driven rollers. The fabric is conveyed using a fabric conveying device on the front side of the frame 1 and a fabric traction device on the rear side of the frame 1. During operation, the fabric, after being opened and torn at the edges, sequentially winds between the first guide roller 41 and the second guide roller 42, then winds around the third guide roller 43 and moves towards the rear side below the frame 1, which is convenient, fast, and provides stable and reliable conveying.
