Figure 1 -ATTACHMENT Figure 5 The technical solutions in the embodiments of the utility model will be described below with reference to the drawings of the embodiments of the utility model.

[0025] Embodiment one: as Figure 1The utility model discloses first specific embodiment provides a kind of cutting machine automatic feeding and positioning structure, including support platform 1, support platform 1 is provided with conveyor belt 2, several positioning blocks 21 are symmetrically provided on conveyor belt, every positioning block 21 has positioning pin 22 with one-to-one correspondence, cutting device 3 is slidably connected on support platform 1, two pieces of elastic suspension press plate 4 are symmetrically provided on the both sides of support platform 1, several air springs 40 are evenly provided in two pieces of elastic suspension press plate 4, vacuum chamber 5 is provided at the bottom of support platform 1, the top of support platform 1 is evenly provided with several first micro holes 50, several second micro holes 20 are evenly provided on conveyor belt 2.Conveyor belt 2 can continuously and stably convey the material to be cut to the below of cutting device 3 under the drive of power device, realizes automatic feeding function, improves cutting efficiency, the cooperation of positioning block 21 and positioning pin 12 can accurately position material during feeding process, ensure that the position of material is accurate without error when cutting, improve cutting precision, reduce cutting error caused by material position deviation.In addition, during cutting process, elastic suspension press plate 4 applies appropriate pressure to material through internal air spring 40, firmly fixes material on conveyor belt 2, prevents material from displacement or shaking when cutting, further improves cutting precision.And vacuum chamber 5 can produce adsorption effect on material when cutting through the first micro hole 50 at top and the second micro hole 20 on conveyor belt 2, so that material is more closely attached to conveyor belt 2, enhance the stability of material, prevent it from moving during cutting process.

[0026] Two pieces of elastic suspension press plate 4 are fixed on the both sides of support platform 1 by mounting bracket 6, wherein, mounting bracket 6 includes two symmetrically arranged support rods 61, connecting rod 62 is connected between the two support rods, hydraulic cylinder 63 is sleeved on connecting rod 62, and one end of hydraulic cylinder 63 away from connecting rod 62 is fixedly connected with elastic suspension press plate 4.The two symmetrically arranged support rods 61 serve as the main support structure of mounting bracket 6, can be stably fixed on the both sides of support platform 1, provide reliable mounting position for entire elastic suspension press plate 4, ensure that press plate does not displace or shake during working process due to external force.And by controlling the extension and retraction of hydraulic cylinder 63, the height of elastic suspension press plate 4 can be accurately adjusted, so that the distance between press plate and conveyor belt can be adjusted according to the thickness of different materials, thereby ensuring good fixing effect on materials of various thicknesses.

[0027] Each air spring 40 is vertically arranged in the elastic suspension platen 4. The air spring 40 is vertically arranged and can provide elastic force in the vertical direction, that is, the vertical air spring 40 can adaptively adjust the compression degree according to the thickness of the paper, and provide just the right pressure, which can ensure that the paper does not move during cutting, and also will not damage the paper due to excessive pressure. Moreover, the plurality of vertically arranged air springs 40 are uniformly distributed in the elastic suspension platen 4. This uniform distribution allows the pressure to be evenly transmitted to the material surface when the platen is pressed down, ensuring that the material is subjected to stable and uniform pressure throughout the cutting area, which is beneficial to improve the cutting accuracy. In addition, when the cutting device 3 is working, a certain vibration and impact force will be generated, and the air spring 40 can absorb these vibrations to prevent the vibrations from being transmitted to the material, avoid the material from being displaced due to vibration, and also reduce the damage of the vibrations to the equipment itself, prolonging the service life of the equipment.

[0028] The connecting rod 52 has a laser sensor 7 fixed at both ends. The laser sensor 7 can detect the edge position of the material. During feeding, the edge of the material is scanned by a laser beam, which can accurately determine whether the material is in the correct position. In addition, for some cases that need to be cut according to specific dimensions, the laser sensor 7 can monitor the size of the material in real time. By measuring the length, width and other dimensions of the material, the system can control the action of the cutting device 3 according to the preset cutting size requirements, thereby improving the automation and accuracy of cutting.

[0029] The vacuum chamber 5 is fixedly connected with a vacuum pump 8 through a pipeline. The main function is to extract the air in the vacuum chamber 5, so that a negative pressure environment is formed in the chamber. When the first micro air hole 50 at the top end of the vacuum chamber 5 and the second micro air hole 20 on the conveying belt 2 are in contact with the material, the negative pressure environment will generate an adsorption force, thereby preventing the material from being displaced due to vibration of the conveying belt, inertia of the material itself or external factors during conveying. Especially for some materials with light texture and smooth surface, relying solely on the positioning block 21 and the positioning pin 12 and the elastic suspension platen 4 may not be enough to ensure the stability of the material during cutting. The vacuum adsorption force generated by the vacuum pump 8 can work in cooperation with other fixing methods. That is, the vacuum adsorption can make the silk better adhere to the conveying belt 2, and in combination with the pressure of the platen, the stability of the material during cutting can be greatly improved, ensuring the cutting accuracy. Further, when debris and dust are generated during cutting, the vacuum pump 8 also helps to suck these impurities into the vacuum chamber 5 during operation. At the same time of extracting air to form negative pressure, the surrounding debris and dust will be sucked in with the airflow, which helps to keep the cutting work area clean and prevents the accumulation of debris from affecting the cutting quality.

[0030] The cutting device 3 is slidably connected with the support platform 1 through the first sliding support 31, wherein the first sliding support 31 comprises two first sliding rods 311 symmetrically arranged on the support platform 1, a first rotating rod 312 connected between the two first sliding rods 311, an extension rod 313 sleeved with the first rotating rod 312, and a cutting machine 30 fixed at one end of the extension rod 313 close to the support platform 1. The two symmetrically arranged first sliding rods 311 cooperate with the support platform 1 to enable the cutting device 3 to stably slide on the support platform 1. Through the sliding cutting device 3, the cutting position can be accurately adjusted to ensure the accuracy of cutting. In addition, the combination of the first rotating rod 312 and the sleeved extension rod 313 further increases the flexibility of the position adjustment of the cutting device 3. The first rotating rod 312 can make the cutting machine 30 rotate around the shaft by a certain angle, and the extension rod 313 can change the distance between the cutting machine 30 and the first rotating rod 312, thereby adjusting the height or length of the cutting machine 30, adapting to the cutting requirements of materials of different thicknesses, and better controlling the cutting depth.

[0031] A driving motor 9 is connected to one side of the first rotating rod 312 and fixed on the first sliding rod 311. The main function of the driving motor 9 is to provide rotating power for the first rotating rod 312. This rotating function can meet the cutting requirements of some special shapes or angles, such as cutting rectangular materials into trapezoidal or triangular shapes.

[0032] The hydraulic cylinder 63, the laser sensor 7, the vacuum pump 8, the extension rod 313, and the driving motor 9 are respectively connected with the terminal control device.

[0033] Working principle: in use, first of all, the material is placed on the conveyor belt 2, the conveyor belt 2 starts to run under the drive of the power device, and the material is transported to the cutting device 3. During the conveying process, the positioning block 21 on the conveyor belt moves with the material, and when the material reaches the position provided with the positioning pin 22 on the support platform 1, the positioning block 21 cooperates with the positioning pin 22 to preliminarily position the material, ensuring that the position of the material in the transverse direction is relatively accurate. After the material is positioned, the terminal control device controls the extension and retraction of the hydraulic cylinder 63 according to the thickness and other information of the material, so that the elastic suspension pressing plate 4 on both sides of the support platform 1 moves downward, and when the pressing plate contacts the material, the air spring 40 vertically arranged inside the elastic suspension pressing plate 4 is compressed, generating an upward elastic force, which gently presses the material. Because the air spring 40 is uniformly distributed, the pressure is uniformly distributed on the surface of the material. At the same time, the terminal control device controls the vacuum pump 8 to start working, and the air in the vacuum chamber 5 is pumped out to form a negative pressure environment in the chamber. The first micro air hole 50 at the top of the vacuum chamber 5 and the second micro air hole 20 on the conveyor belt 2 adsorb the material on the conveyor belt 2, together with the elastic suspension pressing plate 4, to fix the material from the top and bottom directions, enhancing the stability of the material during cutting. After the material is fixed, the laser sensor 7 scans the material and sends the edge position, size and other information of the material to the terminal control device, and the terminal control device judges whether the material is in the best cutting position according to the information. If there is deviation, adjust the position of the cutting device 3, two first sliding rods 311 enable the cutting device 3 to slide horizontally on the support platform 1, the first rotating rod 312 and the telescopic rod 313 connected with the outer sleeve can adjust the height of the cutting machine 30, that is, by controlling the terminal control drive motor 9 to drive the first rotating rod 312 to rotate, the cutting machine 30 can move relatively in the axial position of the first rotating rod 312, and correspondingly the telescopic rod 313 also extends and retracts under the control of the terminal control device, adjusting the height or extension length of the cutting machine 30 to adapt to the thickness and cutting depth requirements of the material. When the cutting device 3 is adjusted to the appropriate position and angle, the cutting machine 30 starts to work and cuts the fixed material. During the cutting process, the air spring 40 of the elastic suspension pressing plate 4 continues to provide stable pressure, and the vacuum adsorption also continuously maintains the fixed state of the material, ensuring the cutting accuracy. At the same time, the laser sensor 7 continuously monitors the material position, and if the material has a small displacement, the terminal control device will adjust the position of the cutting device 3 in time; the vacuum pump 8 also continuously works to maintain the vacuum adsorption, and can suck the debris and other impurities generated during the cutting process into the vacuum chamber 5, keeping the working area clean.
