[0002] A cutting machine is a common fabric cutting device that typically uses CNC or laser methods to cut the fabric on a table along a path.
[0003] Existing cutting machines typically use adsorption to hold the fabric tightly against the cutting table surface, preventing the fabric from slipping during cutting and ensuring cutting accuracy. However, the adsorption area is usually set by the operator or by a pressure sensor, which has problems such as response delay and complex operation. It is difficult to achieve true on-demand adsorption, and there is a technical contradiction between energy waste and insufficient adsorption force.
[0004] Therefore, a new solution is needed to supplement the existing product categories of cutting machines. Summary of the Invention

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0018] A partitioned adsorption system for a cutting machine, such as Figures 1-4 As shown, it includes: The table device includes a guide frame 1 and several breathable panels 2. The several breathable panels 2 are joined together along the long side to form a conveying assembly. The guide frame 1 guides the movement of the breathable panels 2. The drive unit pushes the breathable plate 2 located in its drive area; Negative pressure chamber 4 is fixedly installed on the inner wall of the conveying component and is divided into multiple independent strip partitions along the movement direction of the conveying component; The negative pressure device 5 is connected to the negative pressure chamber 4 and is used to remove the air from the negative pressure chamber 4. Each strip section of the negative pressure chamber 4 is equipped with an on / off valve 14 at the end connected to the negative pressure device 5. Control device 17 is used to control the negative pressure device 5 and the drive device; The fabric coverage detection unit is used to detect the position of the fabric on the conveying assembly. The breathable panel 2 has a through-hole area 6, the negative pressure chamber 4 has a gap with several breathable panels 2, and the adjacent breathable panels 2 are connected by connectors 7 to form a close fit. The width of the negative pressure chamber 4 can cover the adsorption hole area 6 on the breathable panel 2. The conveying component surrounds the negative pressure chamber 4, the negative pressure device 5 and the driving device. The fabric coverage detection unit is connected to the control device 17 and the control device 17 independently controls the opening and closing of the corresponding on / off valve 14.
[0019] With this setup, during equipment operation, the negative pressure device 5 draws air from the negative pressure chamber 4 area, allowing air around the working area of the conveying component to flow through the adsorption hole area 6 of the conveying component and into the negative pressure chamber 4 area. This enables the fabric placed on the working area of the conveying component to be adsorbed, achieving a positioning effect during the fabric conveying and cutting processes. During the conveying of the breathable plate 2, the negative pressure chamber 4 and the conveying component are in close contact to reduce the amount of air drawn from the conveying component and the area around the negative pressure chamber 4. The user can control the drive device and the negative pressure device via the control device 17. The operation of 5 forms an automated control, which enables less air to be drawn from the area not covered by fabric between the negative pressure chamber 4 and the negative pressure device 5. The surrounding of the transmission component with the negative pressure chamber 4, the negative pressure device 5 and the drive device is used to bring the negative pressure chamber 4 closer to the fabric, so that the fabric is subjected to stronger suction formed by the negative air pressure. At the same time, it also reduces the problem of the ventilation panel 2 being inconvenient to turn. The negative pressure device 5 includes an air pump 12 and a connecting pipe 13. The connecting pipe 13 connects the air pump 12 and each strip section of the negative pressure chamber 4. Each on and off valve 14 is controlled by the control device 17, which facilitates centralized management by the control device 17.
[0020] The driving device includes a stepper motor 8 and a drive wheel 9 fixedly mounted on the output end of the stepper motor 8. Multiple sets of stepper motors 8 and drive wheels 9 are provided. The driving device synchronously pushes the breathable plate 2 through its drive wheels 9. Two rolling elements 10 are rotatably mounted at both ends of the breathable plate 2, extending into the guide frame 1 and guided by it. The drive wheel 9 is equipped with teeth 11, which push the breathable plate 2 and cause the rolling elements 10 to abut and rotate within the guide frame 1. The drive wheel 9 is driven by the stepper motor 8. The rotation is generated, and the teeth 11 push the breathable plate 2. The rolling elements 10 on the breathable plate 2 are respectively set at the four corners of the breathable plate 2 and extend into the guide frame 1. When the drive wheel 9 pushes the breathable plate 2, the rolling elements 10 reduce the friction between the breathable plate 2 and the guide frame 1 by rolling. The adjacent teeth 11, drive wheel 9 and guide frame 1 form abutment and clearance fit with the breathable plate 2 and the rolling elements 10 respectively, so that the drive wheel 9 pushes the breathable plate 2 more smoothly, and at the same time, it can better ensure the displacement accuracy of the breathable plate 2.
[0021] The fabric coverage detection unit is configured with several light sensing modules 16, which are fixedly installed in their respective negative pressure chambers 4. An illumination panel 15 is installed on the guide frame 1, with the illumination direction of the illumination panel 15 facing the conveying component. The control device 17 is configured to: when the light sensing module 16 above a certain strip section does not detect the light emitted by the illumination panel 15 and passing through the adsorption hole area 6 of the breathable plate 2 during equipment operation, it determines that the area is covered with fabric and opens the corresponding on / off valve 14; when light is detected, it immediately controls the corresponding on / off valve 14 to close.
[0022] The lighting panel 15 emits light. When no fabric is placed on the conveying component, the light passes through the adsorption hole area 6 and illuminates the light sensing module 16. The light sensing module 16 performs real-time monitoring and sends the corresponding signal to the control device 17. When the brightness value detected by the light sensing module 16 is low, it is determined that the corresponding area is covered. The control device 17 processes the data and controls the on / off valve 14 to switch between open and closed states. When the air pump 12 is running, it opens the on / off valve 14 to the negative pressure chamber 4 of the covered area. Conversely, when the brightness value detected by the light sensing module 16 is high, the control device 17 controls the on / off valve 14 to close, preventing too much air from being drawn away by the air pump 12 and ensuring the negative pressure value of other covered areas.
[0023] The connector 7 is set as a magnetic strip. The edge of the breathable plate 2 is provided with a groove for the magnetic strip to be inserted. The magnetic strip is inserted into the groove and its outer surface is flush with the surface of the breathable plate 2. The magnetic strip is set so that the long side of the adjacent breathable plates 2 can attract each other and form an edge fitting effect during the transmission process, so as to reduce the positional displacement that may be caused by inertia during acceleration or deceleration.
[0024] The guide frame 1 covers both ends of the conveying component in the working area. The part outside the working area of the conveying component is the turning area of the breathable plate 2. A gap will be formed between adjacent breathable plates 2 in this area. The covering of the turning area by the guide frame 1 can seal the gap area and prevent fabric or other debris from entering the gap and causing malfunction.
[0025] The cutting machine of this embodiment includes a cutting machine body for fixing to the guide frame 1 of the partition adsorption system. The cutting machine completes the feeding process by moving the conveying component and placing the fabric by the operator. This enables the cutting machine to identify the position of the fabric through its own cutting and identification components, and to perform automated cutting after positioning. The cutting gap can be controlled by the control device 17 to drive the drive device, so that the conveying component can move under the guidance of the guide frame 1 and the push of the stepper motor 8 and the drive wheel 9.
[0026] Working principle: When the air pump 12 is in the start state, the operator places the fabric in the working area of the conveying component. The light sensing module 16 installed in the negative pressure chamber 4 will generate different signals during the detection process and send them to the control device 17. Then, the control device 17 controls the on / off valve 14 at the corresponding position of the negative pressure chamber 4, so that the area of the on / off valve 14 changes from the closed state to the open state, and the air in the negative pressure chamber 4 can be drawn away. The outside air enters the negative pressure chamber 4 through the adsorption hole area 6 on the fabric and the breathable plate 2, thereby fixing the fabric by suction. Then, the user operates the stepper motor 8 through the operation of the control device 17, which drives the drive wheel 9 to rotate. The teeth 11 on the drive wheel 9 push the breathable plate 2 to move under the guidance of the guide frame 1.
