[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] An automatic unloading mechanism for a cutting bed, such as Figures 1-7 As shown, it includes: The conveyor belt 11 and a plurality of first drive rollers 12 and irregular drive rollers 13 connected to the conveyor belt 11 are included. The upper surface of the conveyor belt 11 is the load-bearing area and the lower surface is the non-load-bearing area. Two restraint ropes 14 are provided, and the restraint ropes 14 are in contact with the conveyor belt 11. The first traction component changes the contact position between the binding rope 14 and the bearing area side of the conveyor belt 11; The second traction component alters the contact position between the restraint rope 14 and the non-load-bearing area side of the conveyor belt 11. The frame 15 positions the first drive roller 12, the irregular drive roller 13, the binding rope 14, the first traction component, and the second traction component. The third traction component slides on the frame 15 to tension the binding rope 14 and maintain the contact pressure on the conveyor belt 11. A third track 61 for the sliding of the third traction component is fixedly installed on the frame 15. Each binding rope 14 is equipped with a set of traction components one, two, and three. A synchronizer is installed between traction components one and two to allow them to move synchronously. A first track 21 and a second track 31 are fixedly installed on the frame 15 for the movement of traction components one and two, respectively. A limit switch is installed on traction component one, which can be positioned by abutting against the synchronizer. A controller 16 is installed on the frame 15, which provides drive control for the first drive roller 12, the shaped drive roller 13, and the traction component three. With this setup, during equipment commissioning and operation, the user can adjust the position of the binding rope 14 according to the actual width of the fabric using traction component one. The binding rope 14 can be located at the edge of the fabric. The traction component 2 is adjusted synchronously under the drive of the synchronizer, thereby causing the binding rope 14 to also adjust its position in the non-load-bearing area of ​​the conveyor belt 11. During the process of the fabric being conveyed by the conveyor belt 11, a pull is formed on the fabric. At the same time, when the fabric is conveyed to the area of ​​the shaped drive roller 13, it can continue to be conveyed for a distance on the side of the non-load-bearing area of ​​the conveyor belt 11, and then the binding rope 14 is released from its restriction, forming the effect of separating the cut material from the cut waste. The cut waste is discharged in the non-load-bearing area of ​​the conveyor belt 11. The setting of the shaped drive roller 13 allows the cutting area of ​​the fabric to be expanded, making it easier to separate the material from the waste.

[0021] The traction component includes a first sliding block 22 and a first positioning frame 23 fixedly arranged together. A limiter is fixedly arranged within the first sliding block 22 and the first positioning frame 23. A plurality of guide wheels 17 are rotatably arranged on the first positioning frame 23. The restraint rope 14 forms traction through the guide wheels 17 and forms contact with the conveyor belt 11. The first sliding block 22 is slidably arranged in the area of ​​the first track 21. The first sliding block 22 is positioned on the first track 21 by the limiter. The user changes the position of the first sliding block 22 by controlling the limiter, and restores the position of the first sliding block 22 after releasing the limiter. The guide wheels 17 arranged on the first positioning frame 23 change the traction direction of the restraint rope 14. Simultaneously, the restraining rope 14 is pushed towards the conveyor belt 11, so that the restraining rope 14 can maintain pressure on the conveyor belt 11, thereby forming traction on the fabric being cut. The second traction component includes a second sliding block 32 and a second positioning frame 33. The second sliding block 32 is slidably disposed in the area of ​​the second track 31. Several guide wheels 17 are also rotatably disposed on the second positioning frame 33. The restraining rope 14 forms traction through the guide wheels 17. The second sliding block 32 forms support for the second positioning frame 33, which allows the second positioning frame 33 to move along the direction of the second track 31. Its position change is synchronously displaced by the overall position change of the first traction component and the traction of the synchronizer, so that the restraining rope 14 can correspond to the positions of the first traction component and the second traction component.

[0022] The synchronizer includes a drive shaft 41, a gear belt 42, a first gear 43, and a second gear 44. The drive shaft 41 passes through the first track 21 and is rotatably connected to both the first track 21 and the second track 31. Two sets of gear belts 42, first gears 43, and second gears 44 are provided. The gear belt 42 forms a ring. The first gears 43 are fixedly mounted at both ends of the drive shaft 41, and two first gears 43 are respectively positioned in the areas of the first track 21 and the second track 31. The second gears 44 are rotatably mounted in the middle sections of the first track 21 and the second track 31. The first gears 43 and second gears 44 are drively connected to the gear belt 42, and the first gears 43 and second gears 44 maintain the gear belt 42. In the tensioned state of 2, one side of the first sliding block 22 is configured with teeth 45 that can engage with the gear belt 42, and the opposite side is configured as a plane, through which the limiter can extend and form a meshing and positioning of the gear belt 42. One side of the second sliding block 32 is also configured with teeth 45 that can engage with the gear belt 42, and it is on the same side as the first sliding block 22. During the change of position of the entire traction member, the movement of the first sliding block 22 in the traction member drives the gear belt 42 through the teeth 45 formed thereon. The transmission process of the gear belt 42 synchronously drives the first gear 43 and the second gear 44 to rotate. The first gear 43 drives the transmission shaft 41 to rotate. The second gear 44 is positioned on the first track 21 and the second track 31, thereby keeping the gear belt 42 in a taut state. The taut state of the gear belt 42 on the second track 31, combined with the engagement of the gear belt 42 with the second sliding block 32, drives the second sliding block 32, thus enabling the second positioning frame 33 to move synchronously with the first positioning frame 23. Both the first track 21 and the second track 31 have track grooves 18. The width of the track groove 18 is equal to the width formed by the engagement of the two gear belts 42 with the first sliding block 22 or the second sliding block 32. The width of the track groove 18 is designed to ensure that the gear belt 42 and the first sliding block 22 or the second sliding block 32 are always in a taut state. The interlocking state prevents excessive space and slippage of the gear belt 42 and the first sliding block 22 or the second sliding block 32. The limiter includes two mutually rotatably connected limit rods 51. The two limit rods 51 form an X-shaped structure, and a spring piece 52 is provided between them. The spring piece 52 is kept in a compressed state. The area of ​​the limit rod 51 that extends out of one end of the limiter is also set in a rack shape. The X-shaped structure formed by the two limit rods 51 and the arrangement of the spring piece 52 between the two limit rods 51 are the same as the principle of a clamp. The opening or closing of the spring piece 52 forms the effect of interlocking or opening with the gear belt 42, thereby fixing the first sliding block 22 in the area of ​​the first track 21.

[0023] The traction component three includes a third connecting frame 62 and a drive wheel rotatably mounted on the third connecting frame 62. The drive wheel is driven and controlled by the controller 16 and abuts against the third track 61. Guide wheels 17 are also rotatably mounted on the third connecting frame 62 and the frame 15. During the adjustment of the binding rope 14 by the first positioning frame 23 and the second positioning frame 33, there may be situations where the length of the binding rope 14 is excessive or the tension needs to be adjusted. In order to ensure that the binding rope 14 remains taut and maintains pressure on the conveyor belt 11, the drive wheel drives the third connecting frame 62, so that the guide wheel 17 on the third connecting frame 62 forms traction on the binding rope 14 to tighten the binding rope 14. The direction of movement of the third connecting frame 62 driven by the drive wheel is restricted by the third track 61 and is directed away from the irregular drive roller 13. The guide wheel 17 mounted on the frame 15 forms traction and guidance for the binding rope 14 between the second positioning frame 33 and the third connecting frame 62, and between the third connecting frame 62 and the first positioning frame 23.

[0024] The cross-section of the irregularly shaped drive roller 13 is set as a regular polygon with no fewer than three sides. The diameter of the circumcircle of the regular polygon is no larger than that of the first drive roller 12. The irregularly shaped drive roller 13 expands the cutting area of ​​the cut fabric, facilitating automatic unloading when the fabric reaches the conveyor edge. The first drive roller 12 drives the conveyor belt 11. The rotational speed of the irregularly shaped drive roller 13 is greater than that of the first drive roller 12. The outer surface of the irregularly shaped drive roller 13 is made of stainless steel. To expand the cutting area of ​​the fabric, the edge formed by the irregularly shaped drive roller 13 ensures that the fabric... It generates asynchronous contact, causing the cutting area to curl up at the bend, so that each area of ​​the fabric undergoes at least one support from the protrusion formed by the edge of the irregular drive roller 13, which facilitates peeling. A brush roller 19 is also rotatably mounted on the frame 15. The brush roller 19 is driven and controlled by the controller 16. The brush roller 19 is located at one end close to the irregular drive roller 13 and abuts against the conveyor belt 11. The brush roller 19 is used to peel the finished product required after cutting from the entire fabric, leaving only the cut fabric waste to continue to be transported, thereby achieving the effect of automatic separation of finished product and waste.
