[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-7 As shown, this embodiment proposes... A pressureless conveyor roller cutting device, comprising: Rack 1; The first forming roller 2 is rotatably mounted on the frame 1 in an adjustable position; The second forming roller 3 is rotatably mounted on the frame 1. The first forming roller 2 and the second forming roller 3 form a forming gap 5, through which the semi-finished product passes. The first pressureless conveyor 6 is located at the inlet end of the forming gap 5; The second pressureless conveyor 7 is located at the discharge end of the forming gap 5. The first pressureless conveyor 6 and the second pressureless conveyor 7 have the same structure, both including: The first conveyor 8 has several first through holes 9. The first conveyor 8 is mounted on the frame 1 and is used to convey semi-finished products. The first air collecting box 10 is mounted on the frame 1, and the adsorption hole of the first air collecting box 10 is used to communicate with the first through hole 9.

[0019] In this embodiment, to address the problem that roller cutting devices in related technologies cannot guarantee that elastic materials are always conveyed without stretching during roller cutting, this solution designs a first pressureless conveying component 6 at the inlet end of the forming gap 5 and a second pressureless conveying component 7 at the outlet end of the forming gap 5. The first and second pressureless conveying components 6 and 7 work together to achieve pressureless conveying of the first forming roller 2 and the second forming roller 3 during the forming process. The pressureless conveying principle of both the first and second pressureless conveying components 6 and 7 is based on the adsorption force of the first air collecting box 10. The adsorption force of the first air collecting box 10 acts on the formed semi-finished product through the connected adsorption holes and the first through holes 9, achieving pressureless conveying of the semi-finished product. The several first through holes 9 on the first conveyor 8 move continuously during the conveying process of the semi-finished product. This solution designs several first through holes 9 so that during the movement of several first through holes 9 together, some first through holes 9 will always connect with the adsorption holes of the first air collecting box 10, achieving the purpose of uninterrupted adsorption and conveying of the semi-finished product. The first pressureless conveyor 6 conveys the semi-finished product at the same speed as the first forming roller 2 and the second forming roller 3, achieving simultaneous forming and feeding of the semi-finished product, thus ensuring uninterrupted operation of the equipment. To accommodate semi-finished products of different thicknesses, this solution adjusts the forming gap 5 by adjusting the position of the first forming roller 2.

[0020] Furthermore, the first transmission component 8 includes: The first rotating roller 11 is rotatably mounted on the frame 1 in an adjustable position; The second rotating roller 12 is rotatably mounted on the frame 1 in an adjustable position; The first conveyor belt 13 is movably mounted on the first rotating roller 11 and the second rotating roller 12. The first conveyor belt 13 has an installation space 14. The first through hole 9 is located on the first conveyor belt 13 and communicates with the installation space 14. The first air collection box 10 is located in the installation space 14. The first conveyor belt 13 has a support surface 15. After the first rotating roller 11 and the second rotating roller 12 slide, they are used to adjust the height difference between the supporting surface 15 and the forming gap 5.

[0021] In this embodiment, to achieve the effect of both conveying semi-finished products and always cooperating with the first air collection box 10, the first conveyor 8 is designed as a first conveyor belt 13 that is movable on the first rotating roller 11 and the second rotating roller 12. After adjusting the positions of the first rotating roller 11 and the second rotating roller 12, the height of the supporting surface 15 can be adjusted to ensure that the height difference between the supporting surface 15 and the forming gap 5 is 0. This also prevents the supporting surface 15 from tilting due to uneven ground on which the frame 1 is placed. If the supporting surface 15 is tilted, the semi-finished products will rub against the equipment at the next station when they are conveyed on the supporting surface 15, resulting in a pulling force. This solution can effectively avoid the pulling force by adjusting the first rotating roller 11 and the second rotating roller 12. The first conveyor belt 13 moves on the first rotating roller 11 and the second rotating roller 12, and at the same time, it moves the semi-finished products adsorbed on the first conveyor belt 13 into the forming gap 5.

[0022] Furthermore, it also includes a first feeding component 16, which includes: The first fabric roller 17 is rotatably mounted on the frame 1; The third pressureless conveyor 18 is mounted on the frame 1, and the third pressureless conveyor 18 includes: The second conveyor 19 has several second through holes 20, and one end is rotatably mounted on the frame 1, while the other end is used to abut against the first fabric roller 17. The second conveyor 19 is used to convey the upper fabric 33. The second air collecting box 22 is installed on the frame 1. The adsorption hole of the second air collecting box 22 is used to communicate with the second through hole 20. The second air collecting box 22 is used to generate suction. The first telescopic rod 23 is rotatably mounted on the frame 1 at one end and rotatably mounted on the second conveyor 19 at the other end. After the first telescopic rod 23 extends or retracts, it is used to drive the second conveyor 19 to rotate.

[0023] In this embodiment, since the purchased upper layer fabric 33 is purchased in rolls, in order to convey the purchased upper layer fabric 33 to the forming gap 5, this solution places the roll of upper layer fabric 33 on the first fabric roller 17. Since the first fabric roller 17 is above the forming gap 5, a third pressureless conveying component 18 is required to convey and feed the upper layer fabric 33, preventing the upper layer fabric 33 from being deformed due to pulling force when conveyed from the first fabric roller 17 to the supporting surface 15 of the first pressureless conveying component 6. In order to realize the pressureless conveying function of the third pressureless conveying component 18, this solution ensures that the other end of the second conveying component 19 always abuts against the upper layer fabric 33 placed on the first fabric roller 17. Since the diameter of the roll of upper layer fabric 33 continuously decreases during the feeding process, this solution uses the extension and retraction of the first telescopic rod 23 to drive the second conveying component 19 to rotate, so that the other end of the second conveying component 19 always keeps close to the roll of upper layer fabric 33. The second conveyor 19 is in close contact with the rolled upper fabric 33 but does not create pressure between them. The advantage of this close contact is that the upper fabric 33 can always be parallel to the second conveyor 19 when it is wound out of the first fabric roller 17. The suction force generated by the second air box 22 keeps the upper fabric 33 parallel and attracted to the second conveyor 19, without generating forces in other directions. The second conveyor 19 drives the upper fabric 33 to move, and the moved upper fabric 33 is then conveyed to the support surface 15 of the first conveyor belt 13.

[0024] Furthermore, the second transmission component 19 includes: The third rotating roller 24 is rotatably mounted on the frame 1; The connecting plate 25 has two parts, with the two ends of the third rotating roller 24 rotatably mounted on one end of the connecting plate 25, and the other end of the first telescopic rod 23 rotatably mounted on the connecting plate 25. The fourth rotating roller 26 is rotatably mounted at both ends of the connecting plate 25 at the other end; The second conveyor belt 27 is movably mounted on the third rotating roller 24 and the fourth rotating roller 26.

[0025] In this embodiment, in order to specifically achieve the effect of the second conveyor 19 conveying the upper layer of fabric 33 and the effect of the first telescopic rod 23 driving the second conveyor 19 to rotate after telescopic extension, this solution rotatably sets the third rotating roller 24 and the fourth rotating roller 26 on the connecting plate 25. The connecting plate 25 also has the function of connecting and supporting the third rotating roller 24 and the fourth rotating roller 26. The second conveyor belt 27 moves on the third rotating roller 24 and the fourth rotating roller 26. The first telescopic rod 23 and the connecting plate 25 rotate relative to each other. Therefore, after the first telescopic rod 23 extends or retracts, the connecting plate 25 will rotate. After the connecting plate 25 rotates, it will drive the third rotating roller 24 and the fourth rotating roller 26 to rotate simultaneously. Since the frame 1 is fixed, when the first telescopic rod 23 extends or retracts, the distance between the connection point and the connecting plate 25 will change, and the amount of change is consistent with the effective amount of change after the extension or retraction of the first telescopic rod 23. At the same time, the fixed point of the connecting plate 25 is at the connection point between the third rotating roller 24 and the frame 1. Therefore, the height of the fourth rotating roller 26 and the tilt angle of the connecting plate 25 will change, so that the other end of the second conveyor belt 27 is tightly attached to the rolled upper fabric 33.

[0026] Furthermore, it also includes: Thickness adjusting member 28, the thickness adjusting member 28 includes: The first pressure roller 29 is rotatably mounted on the frame 1; The second pressure roller 30 is rotatably mounted on the frame 1 in an adjustable position. The first pressure roller 29 and the second pressure roller 30 have a squeezing gap 54. The second conveyor 19 is used to convey the upper layer of fabric 33 into the squeezing gap 54. The second pressure roller 30 is used to adjust the size of the squeezing gap 54 after it moves. Also includes: The second feeding component 32 is rotatably mounted on the frame 1. The second feeding component 32 is used to feed the lower layer fabric 55 into the extrusion gap 54. The upper layer fabric 33 and the lower layer fabric 55 form the feeding space 56. The third feeding component 34 is installed on the frame 1 and is used to convey the middle layer material to the feeding space 56.

[0027] In this embodiment, to achieve the sequential extrusion of the upper fabric 33, middle material, and lower fabric 55 into a single unit, the thickness adjustment component 28 adjusts the thickness of the sequentially arranged upper fabric 33, middle material, and lower fabric 55, i.e., adjusts the thickness of the extruded semi-finished product. Different thicknesses achieve different effects, and different finished products require semi-finished products of different thicknesses to be made. Adjusting the position of the second pressure roller 30 allows for adjustment of the extrusion gap 54, which determines the thickness of the extruded semi-finished product. The lower layer fabric 55 is also purchased in rolls, so the second feeding component 32 can be the second fabric roller. After the second fabric roller rotates, it conveys the lower layer fabric 55 to the inlet of the extrusion gap 54. The middle layer material can be fabric or other materials or states of material. After the middle layer material is conveyed to the feeding space 56 by the third feeding component 34, it is also conveyed to the inlet of the extrusion gap 54. Before entering the forming gap 5, the upper layer fabric 33 will first form the feeding space 56 with the lower layer fabric 55 to support the middle layer material. It enters the extrusion gap 54 together with the middle layer material and the lower layer fabric 55 to form a semi-finished product. The rotation speed of the first pressure roller 29 and the second pressure roller 30 is the same as the feeding speed of the first feeding component 16, the second feeding component 32 and the third feeding component 34. The first pressure roller 29 and the second pressure roller 30 extrude material of qualified thickness without affecting the pressureless conveying of the material. The first pressure roller 29 and the second pressure roller 30 also have the same conveying speed as the first unpressurized conveyor 6 and the second unpressurized conveyor 7.

[0028] Furthermore, it also includes: The first wind support component 35 has several parts, all of which are set on the frame 1 and are located at the feeding end of the forming gap 5 respectively; The second wind support component 36 has several parts, all of which are set on the frame 1 and are located at the discharge end of the forming gap 5.

[0029] In this embodiment, due to the gap between the first pressureless conveyor 6 and the forming gap 5, when the semi-finished product is connected to the forming gap 5 on the first pressureless conveyor 6, the semi-finished product may sink at the gap. When the sunken semi-finished product enters the forming gap 5, friction inevitably occurs between the semi-finished product and the second forming roller 3, causing the second forming roller 3 to exert a pulling force on the semi-finished product, causing deformation and affecting the forming process. A gap will also occur between the forming gap 5 and subsequent equipment, causing the formed semi-finished product to sink at the gap. The sunken semi-finished product will then exert friction with subsequent equipment, causing the subsequent equipment to exert a pulling force on the semi-finished product, causing deformation and introducing errors in subsequent work, resulting in unqualified finished products. This solution designs a first wind-powered support 35 and a second wind-powered support 36 to generate stable wind force. The wind force exerts a pushing force on the semi-finished product, further filling the gap and preventing the semi-finished product from sinking. This solution uses wind-powered support instead of ordinary support structures. When supporting semi-finished products, wind generates little or no friction. The friction generated by the semi-finished products would become a pulling force on them. By using wind-powered support, the pulling force can be avoided, achieving pressure-free conveying without any pulling force throughout the entire process.

[0030] Furthermore, it also includes: a cutting output component 37, which includes: The first forming roller 38 is rotatably mounted on the frame 1 in an adjustable position; The second forming roller 40 is rotatably mounted on the frame 1 in an adjustable position. The first forming roller 38 and the second forming roller 40 form a first cutting gap 42. The first cutting gap 42 is connected to the support surface 15 and is used to cut the semi-finished product after pressing. The first receiving roller 43 is rotatably mounted on the frame 1 and is used to collect waste materials. The first conveyor 44 is mounted on the frame 1 and is used to convey finished products.

[0031] In this embodiment, after the semi-finished product is pressed into the required shape within the forming gap 5, it is transferred to the cutting part 37 to cut off the formed shape, thus completing the production of the finished product. Since the thickness of the semi-finished product is adjustable, the positions of the first forming roller 38 and the second forming roller 40 are also adjustable. After adjusting the positions of the first forming roller 38 and the second forming roller 40, the first cutting gap 42 and the forming gap 5 are connected. After the formed shape is cut within the first cutting gap 42, it falls onto the first conveyor 44, which transports the finished product to the next process. Other waste material is wound onto the first receiving roller 43.

[0032] Furthermore, it also includes a cutting output component 37, which includes: The third forming roller 45 is rotatably mounted on the frame 1 in an adjustable position; The fourth forming roller 46 is rotatably mounted on the frame 1 in an adjustable position. The third forming roller 45 and the fourth forming roller 46 form a second cutting gap 48, which is located directly below the discharge end of the second pressureless conveyor 7. The second receiving roller 49 is rotatably mounted on the frame 1 and is used to recycle waste materials. The fourth pressureless conveyor 50 is installed on the frame 1 and is used to convey finished products. Fan 51 is mounted on frame 1 and is located below the second cutting gap 48. Fan 51 is used to assist in the separation of finished products and waste materials.

[0033] In this embodiment, after the semi-finished product is pressed into the required shape within the pressing gap 5, it is transferred to the cutting outlet 37 to cut off the pressed shape, thus completing the production of the finished product. Alternatively, this solution can be implemented by designing the second cutting gap 48 directly below the discharge end of the second pressureless conveyor 7, allowing the cut finished product to fall freely. To facilitate the normal transport of the finished product and waste material on the fourth pressureless conveyor 50 after free fall, this solution uses a blower 51 to generate directional airflow, blowing the falling finished product and waste material into an arc shape, allowing the finished product to be transported by the fourth pressureless conveyor 50. The suction generated by the fourth pressureless conveyor 50 can adsorb the finished product adhering to the waste material. The blower 51 can also assist in winding the waste material onto the second receiving roller 49.

[0034] Furthermore, the cut-out part 37 also includes: The fifth pressureless conveyor 52 is slidably mounted on the frame 1, and the supporting surface 15 of the fifth pressureless conveyor 52 is in communication with the second cutting gap 48. Two baffles 53 are provided on the frame 1. The two baffles 53 are located at the discharge end of the first pressureless conveyor 6 and are used for guidance.

[0035] In this embodiment, to prevent the finished product and waste from oscillating in the air due to wind caused by external factors, a fifth pressureless conveyor 52 is designed to adsorb and convey the finished product and waste. There is a gap between the discharge end of the fifth pressureless conveyor 52 and the second cutting gap 48. In order to facilitate the entry of the finished product and waste into the second cutting gap 48, two baffles 53 are obliquely fixed on the frame 1. The gap formed by the two baffles 53 is connected to the second cutting gap 48. The gap formed by the two baffles 53 near the cutting gap is larger than the second cutting gap 48. The purpose is to ensure that the finished product and waste can still pass between the two baffles 53 after the second cutting gap 48 is changed.
