[0002] When sofa fabrics are used for sofas, anti-termite and antibacterial sofa fabrics are usually used to increase the service life of the sofa fabrics. During the production and processing of the sofa fabrics, the fabrics are cut. When the cutting device is cutting the fabrics, in order to be suitable for sofas of different specifications, the fabrics need to be cut at fixed distances of different specifications.

[0003] The publication number is CN217965376U, which discloses a sofa cushion fabric cutting device, including a base, a cutting seat connected to the center of the upper end of the base, a support frame B connected to the base is arranged above the center of the cutting seat, a through groove is opened at the upper end of the support frame B, and two symmetrically distributed I-shaped sliders are slidably connected to the through groove, and a vertically downward laser cutter is connected to the lower end of the I-shaped slider.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0059] Embodiment 1:

[0060] like Figure 1 and Figure 3 As shown, this embodiment provides a cutting device for cutting the edge of a sofa fabric, comprising a workbench 1 and a laser cutter 2, a feeding mechanism 3, and an adjustment mechanism 4 for adjusting the cutting position of the laser cutters 2 on both sides of the sofa fabric, characterized in that:

[0061] A sleeve plate 5 is sleeved on the laser cutting device 2;

[0062] A connecting plate 51 is arranged on the sleeve plate 5;

[0063] The connecting rod 52 is arranged on the left and right sides of the two connecting plates 51;

[0064] A limiting plate 53 is arranged between two connecting rods 52 on the same side;

[0065] The guide portion 54 is disposed on the workbench 1 and cooperates with the limit plate 53 to guide the sliding limit plate 53 .

[0066] In the present technical solution, the sleeve plate 5 is installed on the laser cutting device 2, and the connecting plate 51 is located on the sleeve plate 5. The arrangement of these two components ensures the close connection between the sleeve plate 5 and the laser cutting device 2, and provides a basis for subsequent operations. Connecting rods 52 are arranged on the connecting plates 51 on the left and right sides, and a limiting plate 53 is placed between the two connecting rods 52 on the same side. The limiting plate 53 helps to ensure that the sofa fabric is cut in the correct position and limits its range of movement. The guide part 54 is arranged on the workbench 1 and cooperates with the limiting plate 53. When the sofa fabric is cut, the sliding limiting plate 53 is guided by the guide part 54, which ensures the accuracy and stability of the cutting process. The cutting of the laser cutting device 2 is adjusted by the adjustment mechanism 4. The position of the sofa is set, and the laser cutting instrument 2 drives the sleeve plate 5 and the connecting plate 51 to move. The connecting plate 51 drives the connecting rod 52 to move, and the connecting rod 52 drives the limiting plate 53 to move, so that the limiting plate 53 limits the position of the sofa to prevent the sofa from being displaced during the cutting process and limits the movement range of the sofa. The feeding mechanism 3 uses a roller to feed the sofa, and the motor provides power to drive the roller to rotate, so that the roller can achieve the purpose of feeding the sofa. Under the action of the limiting plate 53, the movement range of the sofa is limited, so that the laser cutting instrument 2 can cut the sofa more accurately, improve the quality of cutting the sofa, and finally achieve accurate cutting of the edge of the sofa, and ensure the stability and accuracy of the cutting process.

[0067] like Figure 1 and Figure 3 As shown, in this embodiment, the guide portion 54 is optimized to include:

[0068] The fixing blocks 541 are arranged on the left and right sides of the front and rear sides of the top of the workbench 1;

[0069] The guide rod 542 is disposed on the left and right sides of the outer side of the limiting plate 53, and the guide rod 542 is slidably connected to the fixing block 541;

[0070] The elastic member 543 is sleeved on the guide rod 542 and disposed between the fixing block 541 and the limiting plate 53 .

[0071] In the present technical solution, the guide part 54 includes a fixed block 541, a guide rod 542 and an elastic member 543; the fixed block 541 is located at the front and rear sides of the workbench 1, and the guide rod 542 is arranged on the left and right sides of the outer side of the limiting plate 53, and is slidably connected to the fixed block 541, and the elastic member 543 is sleeved on the guide rod 542, playing a buffering role between the fixed block 541 and the limiting plate 53, and the guide rod 542 plays a guiding role in the sliding process of the moving plate, ensuring the accuracy and stability of the cutting process. When the adjustment component adjusts the position of the laser cutting instrument 2 for cutting the sofa cloth, the laser cutting instrument 2 drives the sleeve plate 5 and the connecting plate 51 to move, and the connecting plate 51 is connected. The plate 51 drives the connecting rod 52 to move, the connecting rod 52 drives the limiting plate 53 to move, the limiting plate 53 drives the guide rod 542 to move along the fixed block 541, and the elastic member 543 is compressed. After the laser cutting device 2 is adjusted to the position for cutting the sofa release, the limiting plate 53 also moves to limit the sofa release, thereby limiting the movement range of the sofa release to prevent the sofa release from displacement and affecting the cutting effect. When the cutting work is completed, the adjustment mechanism 4 drives the laser cutting device 2 to move and reset, and the limiting plate 53 also moves and resets, and the elastic member 543 resets accordingly, so that the limiting plate 53 can be guided, thereby ensuring the accuracy and stability of the cutting process.

[0072] like Figure 1 and Figure 3 As shown, in this embodiment, the elastic member 543 is optimized as a buffer spring.

[0073] In the present technical solution, a buffer spring is used as the elastic member 543, which not only has a good effect, but also has the characteristics of easy installation and low cost, thus saving production costs.

[0091] In the present technical solution, the width detection sensor 61 is arranged on the left side of the electric guide rail 43, and its main function is to detect the width of the sofa. When the sofa enters the cutting device, the width detection sensor 61 will measure the width of the sofa and send the relevant information to the control unit 65. The scale 62 is arranged between the upper ends of the two support columns 42, and the slide 63 is opened on the scale 62. The support rod 46 is slidably connected to the slide 63, so that it can be ensured that the support rod 46 can be accurately adjusted according to the scale of the scale 62. The pointer 64 is arranged on the left side of the electric slider 45 and is located on the upper side of the scale 62. The pointer 64 moves with the laser cutter 2. The position of the pointer 64 corresponds to the width of the sofa. The width information of the sofa can be intuitively understood through the position of the pointer 64 on the scale 62. The control unit 65 is electrically connected to the width detection sensor 61, receives the signal detected by the width detection sensor 61, and processes the signal to generate corresponding values. According to these values, the control unit 65 can determine the width of the sofa and control the electric guide rail 43 to adjust the position of the laser cutter 2 for cutting the sofa to ensure accurate cutting of the edge of the sofa. In this way, the detection and control of the width of the sofa is realized, and the position of the laser cutter 2 can be automatically adjusted to achieve accurate cutting of the edge of the sofa.
