According to the search, a weaving edge cutting device of an air loom is disclosed in a patent document with the authorization announcement No. CN221588836U, which comprises a base, symmetrically distributed slide rods are fixedly connected between the base, a threaded rod is rotatably arranged on the left side of the base, a workbench is arranged on the base, a motor is arranged on the workbench, an edge cutter is fixedly arranged on a placing table, the input end of the edge cutter is connected with the output end of the motor in a mortise and tenon joint mode, an adaptive groove is formed in the placing table and can be matched with the blade connected with the output end of the edge cutter, so that the blade can be rotated, the blade can be taken off, and the blade can be taken off and replaced by only removing the mounting screw, a rotating disc is rotatably arranged on the left side of the base, the rotating disc takes the handle as a force receiving end, and the rotating disc can rotate the threaded rod after rotation, so that the workbench can slide left and right through the cooperation of the threaded rod and the slide rod, and the edge cutter can cut the edge cutting position required by different weavings.

[0003] Although the above scheme can meet the basic requirement of cloth edge cutting operation, at least the following problems are still found in actual use: during the edge cutting operation of the cloth, the cut waste cloth cannot be wound and collected, and the cut waste cloth is randomly scattered, which affects the neatness of the production environment, and after the work is completed, the waste cloth needs to be manually collected.

[0004] Therefore, the application provides a weaving edge cutting device of an air-jet loom to solve the above problems. Inventive content

[0005] The application aims to provide a weaving edge cutting device of an air-jet loom, which can simultaneously cut the edges of both sides of the cloth, remove the excess parts of both sides of the cloth, make the cloth reach the required width specification, accurately adjust the position of the cutting blade, adapt to the edge cutting requirement of cloth with different widths, wind the cut waste cloth, avoid the random scattering of the waste cloth, keep the production environment neat, effectively collect the waste cloth, and realize the effect of subsequent processing or recycling of the waste cloth.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a cutting edge device for a jet loom, comprising a base and a jet loom, a fabric take-up frame, a fabric take-up mechanism, a guide roller, a cutting edge mechanism, and a waste material take-up mechanism disposed on the base. The jet loom and the fabric take-up frame are both fixedly installed on the top of the base. The jet loom is located on the left side of the fabric take-up frame. The fabric take-up mechanism is disposed on the fabric take-up frame and is used to take up the fabric produced by the jet loom. Two inclined supports are fixedly installed on the top right side of the fabric take-up frame. The two ends of the guide roller are rotatably connected to the sides of the two inclined supports that are close to each other. The same bearing beam is fixedly installed on the right side of the two inclined supports. The cutting edge mechanism is disposed on the bearing beam and is used to cut the fabric edges. The waste material take-up mechanism is disposed on the right side of the fabric take-up frame and is used to take up the cut waste fabric.

[0007] By adopting the above technical solution, the air-jet loom is used to produce fabric. The guide roller can guide the fabric produced by the air-jet loom, which can provide stability for the subsequent winding and edge trimming of the fabric.

[0008] A further configuration of this application is as follows: the fabric winding mechanism includes two rotating shafts, a fabric winding shaft, and a motor. The two rotating shafts are rotatably mounted on the front and rear side walls of the fabric winding frame, respectively, and the ends of the two rotating shafts that are close to each other pass through the front and rear side walls of the fabric winding frame. The fabric winding shaft is detachably mounted and fixed at the ends of the two rotating shafts that are close to each other. The motor is located at the front of the fabric winding frame, and the output shaft end of the motor is fixedly connected to the front end of the corresponding rotating shaft.

[0009] By adopting the above technical solution, the motor is used to drive the rotating shaft to rotate, which in turn drives the fabric winding shaft to rotate to realize the winding operation of the fabric.

[0010] A further feature of this application is that a motor support base is fixedly installed on the front side wall of the fabric winding frame, and the motor is fixedly installed on the motor support base.

[0011] The above technical solution is used to support the motor.

[0012] The further feature of this application is that the number of edge-cutting mechanisms is set to two sets, and the two sets of edge-cutting mechanisms are symmetrically distributed on the load-bearing beam.

[0013] By adopting the above technical solution, it is possible to simultaneously trim the edges of both sides of the fabric.

[0014] A further configuration of this application is as follows: the trimming mechanism includes an electric guide rail, an electric slide block, an electric telescopic rod, a knife holder, and a cutting blade. The electric guide rail is fixedly installed on the top of the load-bearing beam, the electric slide block is slidably installed on the electric guide rail, the electric telescopic rod is fixedly installed on the top of the electric slide block, the knife holder is fixedly installed on the output shaft end of the electric telescopic rod, and the cutting blade is fixedly installed on the top of the knife holder by screws. The cutting blade is located to the lower right of the guide roller.

[0015] By adopting the above technical solution, the horizontal linear movement of the cutting blade can be controlled by the sliding connection of the electric slide on the electric guide rail, and the vertical lifting and lowering of the cutting blade can be controlled by the telescopic feature of the electric telescopic rod. Thus, the position of the cutting blade can be precisely adjusted to meet the cutting edge requirements of fabrics of different widths.

[0016] A further feature of this application is that an electric heating plate is fixedly mounted on the top of the blade holder, and the bottom of the cutting blade contacts the upper surface of the electric heating plate.

[0017] By adopting the above technical solution, the cutting blade can be heated using an electric heating plate, making the cutting smoother and the cut more even.

[0018] The further configuration of this application is as follows: the waste material winding mechanism includes two horizontal supports, two rotating shafts, two waste material winding shafts and a transmission assembly. The two horizontal supports are fixedly installed on the right side of the fabric winding frame. The two rotating shafts rotate through the corresponding horizontal supports respectively. The two waste material winding shafts are detachably installed and fixed at the two rotating shafts that are close to each other. The transmission assembly is used to control the two rotating shafts and the rotating shaft to rotate simultaneously.

[0019] By adopting the above technical solution, two waste material winding shafts can be used to wind up the waste fabric cut from both sides of the fabric.

[0020] A further configuration of this application is: the transmission assembly includes two main pulleys, two auxiliary pulleys and two belts, the two main pulleys are respectively fixedly mounted on the ends of two rotating shafts that are far apart from each other, the two auxiliary pulleys are respectively fixedly mounted on the ends of two rotating shafts that are far apart from each other, one end of the two belts is respectively wound around the corresponding main pulleys, and the other end of the two belts is respectively wound around the corresponding auxiliary pulleys.

[0021] By adopting the above technical solution, the transmission action of two sets of main pulleys, auxiliary pulleys and belts can ensure that the two waste material winding shafts and the fabric winding shaft rotate synchronously. During the fabric winding process, the cut waste fabric can be wound up in time, avoiding the accumulation of waste material and affecting production.

[0022] A further provision of this application is that the diameter of the main pulley is smaller than the diameter of the auxiliary pulley.

[0023] By adopting the above technical solution, it can be ensured that the rotation speed of the waste material winding shaft is slightly less than that of the fabric winding shaft, so that the waste fabric wound on the waste material winding shaft is not tight and is relatively loose, which is conducive to the smooth removal of the wound waste fabric from the waste material winding shaft and facilitates the subsequent recycling of waste fabric.

[0024] A further feature of this application is that the outer surface of the guide roller has a smooth surface structure.

[0025] By adopting the above technical solution, the friction between the fabric and the guide roller can be reduced, making the fabric feeding process smoother.

[0026] This application includes at least one of the following beneficial technical effects:

[0027] 1. This application utilizes a fabric winding mechanism consisting of two rotating shafts, a fabric winding shaft, and a motor to perform winding operations on fabric produced by an air-jet loom.

[0028] 2. This application utilizes a trimming mechanism consisting of an electric guide rail, an electric slide, an electric telescopic rod, a blade holder, and a cutting blade. With the combined action of the two trimming mechanisms, the two sides of the fabric can be trimmed simultaneously during the fabric winding process to remove excess fabric from both sides, so that the fabric reaches the required width specification. Furthermore, the position of the cutting blade can be precisely adjusted to adapt to the trimming requirements of fabrics of different widths.

[0029] 3. This application utilizes an electric heating plate to heat the cutting blade. The heated cutting blade reduces the tearing of fabric fibers when cutting fabric, making the cutting smoother, the cut smoother, and improving the quality of the edge treatment.

[0030] 4. This application utilizes a waste material winding mechanism consisting of two horizontal supports, two rotating shafts, two waste material winding shafts, and a transmission assembly. During the winding and trimming process of the fabric, the cut waste fabric can be wound up, preventing the waste fabric from scattering randomly, maintaining a clean production environment, and effectively collecting the waste fabric for centralized subsequent processing or reuse.

[0031] 5. This application allows for the quick replacement of a new fabric take-up shaft after the take-up is completed by detachably installing the fabric take-up shaft on the first rotating shaft, and for the replacement of a new waste material take-up shaft after the waste fabric is fully taken up by detachably installing the waste material take-up shaft on the second rotating shaft.

[0032] 6. By setting the diameter of the main pulley to be smaller than that of the auxiliary pulley, this application ensures that the rotation speed of the waste material winding shaft is slightly lower than that of the fabric winding shaft. This results in the waste fabric being wound on the waste material winding shaft being loose and not tightly packed, which facilitates the subsequent removal of the wound waste fabric from the waste material winding shaft and makes it easier for the waste fabric to be processed or recycled.

[0038] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a fabric trimming device for an air-jet loom, including a base 1 and an air-jet loom 2, a fabric take-up frame 3, a fabric take-up mechanism, a guide roller 9, a trimming mechanism 11, and a waste material take-up mechanism mounted on the base 1. The air-jet loom 2 and the fabric take-up frame 3 are both fixedly installed on the top of the base 1. The air-jet loom 2 is located to the left of the fabric take-up frame 3. The air-jet loom 2 is used to produce fabric, wherein:

[0040] The fabric winding mechanism is mounted on the fabric winding frame 3. This mechanism is used to wind up the fabric produced by the air-jet loom 2. The fabric winding mechanism includes two rotating shafts 4, a fabric winding shaft 5, and a motor 6. The two rotating shafts 4 are rotatably mounted on the front and rear side walls of the fabric winding frame 3, respectively, with their ends penetrating the front and rear side walls of the fabric winding frame 3. The fabric winding shaft 5 is detachably mounted and fixed to the ends of the two rotating shafts 4 that are close to each other. The motor 6 is located at the front of the fabric winding frame 3, and the output shaft end of the motor 6 is connected to the corresponding rotating shaft. The front end of shaft 4 is fixedly connected to the motor 6, which drives shaft 4 to rotate, thereby driving the fabric take-up shaft 5 to rotate to realize the take-up operation of the fabric. The fabric take-up shaft 5 is detachably installed on shaft 4, which makes it convenient to quickly replace the new fabric take-up shaft 5 after the take-up is completed. Two inclined brackets 8 are fixedly installed on the top right side of the fabric take-up frame 3. The two ends of the guide roller 9 are rotatably connected to the two inclined brackets 8 respectively. The guide roller 9 can guide the fabric produced by the air-jet loom 2, which can provide stability for the subsequent take-up and edge cutting of the fabric.

[0041] In this embodiment, a motor support 7 is fixedly installed on the front side wall of the fabric winding frame 3, and the motor 6 is fixedly installed on the motor support 7. The motor support 7 ensures that the motor 6 is installed stably, thereby making the winding process stable and reliable, which helps to ensure the uniformity and tightness of the fabric winding.

[0042] In this embodiment, the same supporting beam 10 is fixedly installed on the right side of the two inclined supports 8. A trimming mechanism 11 is installed on the supporting beam 10. The trimming mechanism 11 is used to trim the fabric edges. Two sets of trimming mechanisms 11 are symmetrically distributed on the supporting beam 10, enabling simultaneous trimming of both sides of the fabric. This ensures the symmetry and accuracy of the trimming, resulting in neat edges and improved product quality. The trimming mechanism 11 includes an electric guide rail 111, an electric slide block 112, an electric telescopic rod 113, a blade holder 114, and a cutting blade 115. The electric guide rail 111 is fixedly installed on the top of the supporting beam 10. The slide block 112 is slidably mounted on the electric guide rail 111. The electric telescopic rod 113 is fixedly mounted on the top of the electric slide block 112. The blade holder 114 is fixedly mounted on the output shaft end of the electric telescopic rod 113. The cutting blade 115 is fixedly mounted on the top of the blade holder 114 by screws. The cutting blade 115 is located to the lower right of the guide roller 9. By utilizing the sliding connection between the electric slide block 112 and the electric guide rail 111, the horizontal linear movement of the cutting blade 115 can be controlled. By utilizing the telescopic feature of the electric telescopic rod 113, the vertical lifting and lowering of the cutting blade 115 can be controlled. Thus, the position of the cutting blade 115 can be precisely adjusted to meet the cutting requirements of fabrics of different widths.

[0043] In this embodiment, an electric heating plate 116 is fixedly installed on the top of the blade holder 114, and the bottom of the cutting blade 115 is in contact with the upper surface of the electric heating plate 116. The electric heating plate 116 can heat the cutting blade 115. The heated cutting blade 115 can reduce the tearing of fabric fibers when cutting the fabric, making the cutting smoother and the cut smoother. It should be noted that the electric heating plate 116 is an adjustable temperature electric heating plate, and its heating temperature is set according to the material of the fabric being produced.

[0044] In this embodiment, the waste material winding mechanism is located on the right side of the fabric winding frame 3. The waste material winding mechanism is used to wind up the cut waste fabric. It includes two horizontal supports 12, two rotating shafts 13, two waste material winding shafts 14, and a transmission assembly. Both horizontal supports 12 are fixedly installed on the right side of the fabric winding frame 3. The two rotating shafts 13 rotatably pass through their respective horizontal supports 12. The two waste material winding shafts 14 are detachably installed and fixed at the adjacent ends of the two rotating shafts 13. The transmission assembly controls the simultaneous rotation of the two rotating shafts 13 and the first rotating shaft 14. The transmission assembly includes two main pulleys 15, two auxiliary pulleys 16, and two belts 17. The two main pulleys 15 are fixedly installed on the right side of the fabric winding frame 3. The fixed sleeve is mounted on the two rotating shafts 1-4 at their respective ends, and the two auxiliary pulleys 16 are respectively fixedly mounted on the two rotating shafts 2-13 at their respective ends. One end of each of the two belts 17 is wound around the corresponding main pulley 15, and the other end of each of the two belts 17 is wound around the corresponding auxiliary pulley 16. By utilizing the transmission action of the two sets of main pulleys 15, auxiliary pulleys 16 and belts 17, it can be ensured that the two waste material winding shafts 14 and the fabric winding shaft 5 rotate synchronously. During the fabric winding process, the cut waste fabric can be wound up in time, avoiding the accumulation of waste material and affecting production. The waste material winding shaft 14 is detachably mounted on the rotating shaft 2-13, which makes it easy to replace the waste material winding shaft 14 after the waste fabric is fully wound.

[0045] In this embodiment, the diameter of the main pulley 15 is smaller than that of the auxiliary pulley 16, which ensures that the rotation speed of the waste material winding shaft 14 is slightly less than that of the fabric winding shaft 5. This makes the waste fabric wound on the waste material winding shaft 14 less compact and more loose, which is beneficial for the subsequent removal of the wound waste fabric from the waste material winding shaft 14, facilitating the subsequent processing or recycling of the waste fabric.

[0046] In this embodiment, the outer surface of the guide roller 9 is a smooth surface, which can reduce the friction between the fabric and the guide roller 9, making the fabric feeding process smoother, reducing the possibility of fabric surface damage and wrinkling, and facilitating subsequent edge trimming and winding operations.

[0047] In this embodiment, it should be noted that the motor 6, electric guide rail 111, electric slide block 112, electric telescopic rod 113, and electric heating plate 116 can all be purchased on the market. The motor 6, electric guide rail 111, electric slide block 112, electric telescopic rod 113, and electric heating plate 116 are equipped with power supplies, and their wiring connection methods and control methods are mature technologies in this field, so they will not be described in detail here.

[0048] With the above structure, the working principle of the air-jet loom weaving edge trimming device provided in this application is as follows:

[0049] Fabric roll

[0050] Start the air-jet loom 2 to weave the fabric. First, pass one end of the produced fabric over the top of the guide roller 9 and then wind it onto the fabric take-up shaft 5. By controlling the operation of the motor 6, the motor 6 drives the rotating shaft 4 to rotate, which in turn drives the fabric take-up shaft 5 to rotate. The fabric can then be gradually wound onto the fabric take-up shaft 5 to achieve the fabric take-up operation.

[0051] Fabric trimming

[0052] By controlling the two electric slide blocks 112 to slide horizontally and linearly on the corresponding electric guide rails 111, the two cutting blades 115 can be adjusted to the parts of the fabric that need to be cut on both sides. Then, by controlling the two electric telescopic rods 113 to extend, the two cutting blades 115 can be controlled to move vertically upward. When the two cutting blades 115 come into contact with the fabric, they will cut the fabric until they abut against the outer wall of the guide roller 9. As the fabric is gradually rolled up on the fabric winding shaft 5, the cutting operation on both sides of the fabric can be realized simultaneously, removing the excess part on both sides of the fabric, so that the fabric reaches the required width specification.

[0053] Waste fabric roll

[0054] When simultaneously trimming both sides of the fabric, the transmission action of two sets of main pulleys 15, auxiliary pulleys 16, and belts 17 ensures that the two waste material winding shafts 14 and the fabric winding shaft 5 rotate synchronously. By winding and fixing one end of the cut waste fabric onto the corresponding waste material winding shaft 14, the rotation of the two waste material winding shafts 14 can be used to wind up the cut waste fabric, preventing the waste fabric from scattering randomly, maintaining a clean production environment, and achieving effective collection of waste fabric so that it can be centrally processed or reused.
