[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0021] like Figure 1-Figure 9 As shown, in some embodiments, the present invention relates to a cutting device for producing woven bags, including a frame 8. In particular, a cutting assembly 2, a traction assembly 4 and a guide assembly 5 are provided on the frame 8. Among them, the cutting assembly 2 is arranged at the front end position of the traction assembly 4, and the traction assembly 4 pulls the woven bag 9 to be cut forward along the correct route. It should be particularly noted that the moving distance of the traction assembly 4 is determined according to the length of the woven bag 9. The guide assembly 5 is arranged on one side of the traction assembly 4 to ensure that the woven bag 9 can be accurately moved in the correct direction after cutting. The design of this equipment is intended to improve the efficiency and accuracy of the woven bag 9 production process while ensuring the quality of the product.

[0022] Specifically, the cutting assembly 2 includes two impurity removal mechanisms 25 and a cutting mechanism 27. The two impurity removal mechanisms 25 are respectively arranged at the two ends of the incision of the woven bag 9. The cutting mechanism 27 is respectively connected to the impurity removal mechanism 25 during the movement to ensure that the impurity removal mechanism 25 can effectively remove the debris remaining in the process of cutting the woven bag 9 by the cutting mechanism 27 to ensure the stable operation of the cutting mechanism 27.

[0023] In particular, the cutting mechanism 27 includes a cutter 271 for cutting the woven bag 9. The impurity removal mechanism 25 includes a plurality of impurity removal blocks 251, which are arranged on both sides of the cutter 271, and their main function is to remove impurities attached to the surface of the cutter 271 when cutting the woven bag 9, to ensure the cleanliness and smoothness of the cutting process, and to improve the neatness of the cut of the woven bag 9.

[0024] In addition, the traction assembly 4 includes an adsorption mechanism 42, which is used to firmly adsorb one end of the cut woven bag 9 so that the woven bag 9 can be accurately moved forward. By accurately adjusting the moving distance of the adsorption mechanism 42, it is ensured that the length of the woven bag 9 meets the production requirements. In the process of using the adsorption mechanism 42 to pull the woven bag 9 forward, the stability of its moving path is ensured, the woven bag 9 is effectively prevented from tilting, and the cut woven bag 9 is ensured to maintain a good squareness.

[0025] The guide assembly 5 includes a roller mechanism 53, which is used to guide the movement of the woven bag 9 from above to ensure that the woven bag 9 can stably move to the next operating station after cutting. The design of the roller mechanism 53 takes into account the movement requirements of the woven bag 9 during the cutting process. Through precise guidance and control, it can ensure that the woven bag 9 can move quickly after cutting to avoid overlapping of the woven bag 9, thereby improving cutting efficiency and quality.

[0026] It is worth noting that when one end of the woven bag 9 is sucked by the adsorption mechanism 42 and moved forward along with the adsorption mechanism 42, when the woven bag 9 moves to the specified position, the cutter 271 cuts along the transverse direction of the woven bag 9 to divide the woven bag 9 into independent parts. When the cutter 271 works, the adsorption mechanism 42 moves to the initial position. When the cutter 271 completes the cutting, the roller mechanism 53 conveys the cut woven bag 9 forward along the conveying track to continue the sewing of the woven bag 9 and other operations.

[0027] like Figure 5 As shown, in some embodiments, the frame 8 includes a cutting table 81 and a conveying table 83. The cutting table 81 is arranged on the side of the conveying table 83. The woven bag 9 is first cut at the cutting table 81, and then the conveying table 83 moves the cut woven bag 9 to the next process.

[0028] In particular, a cutting groove 82 is specially provided on the surface of the cutting table 81, and the cutting groove 82 is designed to cooperate with the cutting assembly 2. The cutter 271 in the cutting assembly 2 can smoothly pass through the cutting groove 82, thereby accurately cutting the woven bag 9. At the same time, a conveying groove 84 is also provided on the conveying assembly 7, and the conveying groove 84 corresponds to the position of the pressing roller mechanism 53. Such a design ensures the stability and accuracy of the woven bag 9 during the conveying process, thereby improving the efficiency and quality of the entire production process.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, in some embodiments, the cutting assembly 2 also includes a first screw rod 21, a first slider 22, a first motor 23, two accommodating frames 24 and a guide frame 26. Specifically, both ends of the first screw rod 21 are connected to the lower part of the cutting table 81 to ensure its stability and precise cutting position. The first motor 23 is arranged at one end of the first screw rod 21 and is responsible for driving the first screw rod 21 to rotate. The first slider 22 is transmission-connected to the first screw rod 21 so that the first slider 22 can move along the axial direction of the first screw rod 21, thereby realizing the precise positioning of the cutting mechanism 27. The cutting mechanism 27 is fixedly connected to the first slider 22 to ensure that the cutting mechanism 27 can move synchronously when the first slider 22 moves to complete the cutting of the woven bag 9.

[0030] In addition, two receiving frames 24 are respectively arranged at both ends of the guide frame 26, and the receiving frame 24 and the guide frame 26 are integrally installed in the cutting groove 82. The impurity removal mechanism 25 is arranged in the receiving frame 24, and its function is to remove impurities attached to the cutter 271 when cutting the woven bag 9 during the cutting process, so as to prevent these impurities from affecting the quality of the next cutting.

[0031] Furthermore, in some embodiments, the impurity removal mechanism 25 further includes a plurality of damping rods 252, which are arranged in a corresponding relationship with the plurality of impurity removal blocks 251. Specifically, there are four impurity removal blocks 251, which are arranged symmetrically in pairs, and each impurity removal block 251 is fixedly connected to the inner wall of the containing frame 24 through the damping rod 252. Such a design enables the damping rod 252 to effectively adjust the distance between the impurity removal block 251 and the cutter 271, so that the impurity removal block 251 can effectively remove impurities on the cutter 271, so as to improve the cutting accuracy and the cutting quality of the woven bag 9.

[0032] In addition, the design of the impurity removal block 251 is also quite ingenious. It is set to have a certain tilt angle, and the slope formed by the tilt angle faces the direction of the woven bag 9, so as to facilitate the cutter 271 to enter the receiving frame 24. The design of this tilt angle helps to improve the efficiency of impurity removal, so that when the cutter 271 passes between two impurity removal blocks 251, the impurity removal block 251 can effectively remove impurities on the cutter 271, ensure the cleanliness of the cutter 271, and thus ensure the neatness of the cutting mouth.

[0033] Furthermore, in some embodiments, the cutting mechanism 27 further includes a connecting sleeve 272. The connecting sleeve 272 is used to connect the cutter 271 and the first slider 22. The connecting sleeve 272 is threadedly connected to the first slider 22 to facilitate the replacement and maintenance of the cutter 271 in the later stage.

[0034] like Figure 2 , Figure 4 and Figure 8 As shown, in some embodiments, the traction assembly 4 further includes a second screw rod 41 and a second motor 43. Specifically, the second motor 43 is disposed at one end of the second screw rod 41 to provide power for the second screw rod 41. In addition, the second screw rod 41 is connected to the adsorption mechanism 42 through a transmission device, so that the second motor 43 can drive the adsorption mechanism 42 to move through the second screw rod 41, thereby achieving the displacement of the woven bag 9.

[0035] Further, in some embodiments, the adsorption mechanism 42 includes a second slider 421, a plurality of fixing plates 422, a plurality of suction cups 423, a second telescopic rod 425, and a first connecting plate 426. The second slider 421 is transmission-connected to the second screw rod 41, thereby ensuring the precise movement of the adsorption mechanism 42. The two ends of the second telescopic rod 425 are respectively firmly connected to the second slider 421 and the first connecting plate 426, and the height of the first connecting plate 426 is adjusted by the second telescopic rod 425.

[0036] In particular, a plurality of slide grooves 424 are provided on the first connecting plate 426, and these slide grooves 424 are arranged corresponding to the plurality of fixed plates 422. The slide grooves 424 and the fixed plates 422 can be slidably connected, and such a design allows the fixed plates 422 to move appropriately in the slide grooves 424 to achieve the best adsorption position.

[0037] In addition, each fixing plate 422 is firmly connected to the suction cup 423, ensuring the stability of the suction cup 423, thereby providing stable support for the cutting process.

[0038] It should be noted that when the adsorption mechanism 42 is in the initial position, the second telescopic rod 425 extends, driving the first connecting plate 426 to move downward, and the suction cup 423 also moves downward, so that the suction cup 423 absorbs one end of the woven bag 9. Driven by the second screw rod 41, the second slider 421 moves along the second screw rod 41. When it moves to the specified position, the suction cup 423 releases the woven bag 9, so that the woven bag 9 is laid flat on the conveyor table 83, and the woven bag 9 is cut by the cutter 271. At this time, the second screw rod 41 rotates in the opposite direction to move the adsorption mechanism 42 to the initial position, and the operation is repeated to complete the precise control of the cutting length of the woven bag 9. Through the forward and reverse rotation of the second screw rod 41 and the second motor 43, the woven bag 9 can be accurately positioned, thereby improving the accuracy and repeatability of the cutting.

[0039] like Figure 2 , Figure 4 and Fig. 9As shown, in some embodiments, the guide assembly 5 further includes a third motor 51, a third screw rod 54 and a second cross plate 52. Specifically, the third motor 51 is disposed at one end of the third screw rod 54, and the third screw rod 54 is transmission-connected to the roller mechanism 53, so that the third motor 51 can drive the third screw rod 54 to rotate, thereby driving the roller mechanism 53 to move.

[0040] Meanwhile, the second transverse plate 52 is disposed on the upper part of the third screw rod 54, and a protrusion is disposed on the second transverse plate 52, and these protrusions are slidably connected with the pressure roller mechanism 53, thereby ensuring that the pressure roller mechanism 53 can move smoothly along the third screw rod 54. The function of the protrusion is to guide the pressure roller mechanism 53 to move along the third screw rod 54, thereby ensuring the accuracy and stability of the movement of the pressure roller mechanism 53.

[0041] Furthermore, in some embodiments, the pressure roller mechanism 53 includes a third slider 531 , a third telescopic rod 532 , a second connecting plate 533 , a plurality of rollers 534 , a connecting rod 535 and a fourth motor 536 .

[0042] Specifically, the third slider 531 is connected to the third screw rod 54 by transmission, and the third slider 531 and the second connecting plate 533 are connected into a whole by the third telescopic rod 532, and the height of the second connecting plate 533 is adjusted by the third telescopic rod 532. The connecting rod 535 is connected to the second connecting plate 533 by a fixed frame, which ensures that the connecting rod 535 can rotate stably, and the rollers 534 are fixedly connected to the connecting rod 535, and the rollers 534 are arranged in the fixed frame, and one end of the connecting rod 535 is connected to the fourth motor 536 by transmission, and the fourth motor 536 drives the rollers 534 to rotate through the connecting rod 535. An anti-skid pad is provided on the surface of the roller 534, and the anti-skid pad can effectively drive the woven bag 9 to be transported forward when the roller 534 rotates.

[0043] In addition, a slide rail is designed on the top of the third sliding block 531, and the slide rail is slidably connected with the protrusion, so that the third sliding block 531 remains stable when moving.

[0044] like Figure 1-Figure 4 As shown, in some embodiments, the device further includes a guide roller 1, a pressing assembly 3, a detection assembly 6 and a conveying assembly 7. The guide roller 1 is arranged at the front side of the cutting table 81, and its main function is to convey the woven bag 9 to be cut. The guide roller 1 can effectively move the woven bag 9 forward by arranging an anti-slip pad on its surface, ensuring that the woven bag 9 can maintain the correct direction and position before reaching the cutting assembly.

[0045] The clamping assembly 3 is arranged on the upper part of the cutting table 81 and on both sides of the cutting assembly 2. Its main function is to ensure that the woven bag 9 remains stable during the cutting process. The clamping assembly 3 can prevent the woven bag 9 from being displaced due to vibration or other external forces during cutting through its clamping force, thereby ensuring the accuracy of cutting.

[0046] The detection component 6 is arranged on the upper part of the traction component 4, and its main function is to detect the position of the woven bag 9, so as to ensure the accuracy of cutting. The detection component 6 usually includes an optical sensor, which can monitor the position and state of the woven bag 9 in real time and provide accurate cutting position information for the cutting component.

[0047] The conveying assembly 7 is arranged corresponding to the pressing roller mechanism 53 to ensure smooth conveying of the woven bag 9. The conveying assembly 7 ensures that the woven bag 9 can move smoothly during the conveying process through a series of conveyor belts to avoid production interruption or damage to the woven bag 9 caused by poor conveying.

[0048] In particular, the clamping assembly 3 includes a fixed rod 31, a first telescopic rod 32 and a first cross plate 33. The two ends of the first telescopic rod 32 are respectively fixedly connected to the fixed rod 31 and the first cross plate 33, so that the telescopic rod 32 can drive the fixed rod 31 to move synchronously when it is extended and retracted. The first telescopic rod 32 ensures the uniform distribution of the clamping force through its telescopic function. The first cross plate 33 is fixedly connected to the frame 8 to ensure the stability of the entire clamping assembly 3. As a supporting structure, the first cross plate 33 not only provides sufficient strength and rigidity, but also ensures that the clamping assembly 3 will not be deformed during operation. The first telescopic rod 32 can drive the fixed rod 31 to move, while the fixed rod 31 is directly used to clamp the woven bag 9 to ensure that the woven bag 9 will not be displaced during the cutting process, thereby improving the cutting accuracy and efficiency. The fixed rod 31 can apply uniform pressure by directly contacting the surface of the woven bag 9 to prevent the woven bag 9 from being deformed or damaged due to uneven force during the cutting process.
