[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] refer to Figure 1-7 A seamless underwear processing system includes a frame 1, on which a conveying mechanism for conveying underwear raw materials is provided, the conveying mechanism includes a first conveying roller 101, a first guide roller 102, a first tensioning roller 103, a second tensioning roller 104, a second guide roller 105, a second conveying roller 106, which are sequentially arranged on the frame 1 and rotatably connected to the frame 1, and a driving component for driving the first conveying roller 101 and the second conveying roller 106 to rotate simultaneously, the first tensioning roller 103 and the second tensioning roller 104 are at the same level, the first guide roller 102 and the second guide roller 105 are higher than the first conveying roller 101 and the second conveying roller 106, the driving mechanism generally includes a rotating motor and a synchronous pulley group connecting the first conveying roller 101 and the second conveying roller 106, and the prior art well known to those skilled in the art is not described in detail.

[0020] Furthermore, it also includes a cutting mechanism for cutting underwear raw materials, which is arranged on the top of the frame 1 and located between the first tensioning roller 103 and the second tensioning roller 104. A movable groove 107 is arranged on one side of the frame 1 close to the first tensioning roller 103 and the second tensioning roller 104. The first tensioning roller 103 and the second tensioning roller 104 are both rotatably connected to the inner wall of the movable groove 107 through a rotating shaft 108. It also includes a pushing mechanism for pushing the first tensioning roller 103 and the second tensioning roller 104 away from each other before the cutting mechanism cuts the fabric.

[0021] A pushing mechanism is provided so that the cutting mechanism can push the first tensioning roller 103 and the second tensioning roller 104 away from each other before cutting the cloth 7, thereby further stretching the cloth 7 and reducing deformation and wrinkles of the cloth 7 during cutting. At the same time, pushing the first tensioning roller 103 and the second tensioning roller 104 away from each other can open the yarn in the cloth 7, and the opened yarn helps to keep the fabric flat, avoid wrinkles or irregular shapes during the cutting process, ensure cutting accuracy, and thus improve the quality and consistency of the final product.

[0022] Specifically, the cutting mechanism includes a support frame 2, a cutting knife 201, a cutting cylinder 202, and a workbench 203 arranged on the frame 1. The cutting knife 201 is arranged between the support frame 2 and the frame 1, the cutting cylinder 202 is arranged on the top of the support frame 2, and the telescopic rod of the cutting cylinder 202 is fixedly connected to the cutting knife 201, the workbench 203 is arranged at the bottom of the frame 1, and the top of the workbench 203 corresponds to the position of the cutting knife 201. A lifting mechanism for controlling the lifting of the workbench 203 is provided on the support frame 2, and the lifting mechanism can first drive the workbench 203 to contact the bottom of the cloth 7 before the cutting knife 201 cuts the cloth 7.

[0023] During use, when the cloth 7 is conveyed to a suitable length, the cutting cylinder 202 is started, and the telescopic rod of the cutting cylinder 202 drives the cutting knife 201 to move downward and cut the cloth. While the cutting knife 201 is moving, the lifting mechanism will first drive the workbench 203 to contact the bottom of the cloth 7 before the cutting knife 201 cuts the cloth 7, playing the role of pre-supporting the cloth 7, avoiding the shaking or displacement of the cloth 7 due to the lack of support below during cutting, thereby further improving the cutting accuracy. It should be noted that when the cutting knife 201 cuts the cloth 7, the cutting knife 201 will not directly cut the cloth, but leave a certain space to ensure that the cloth 7 can be conveyed smoothly.

[0024] Furthermore, a guide rod 204 is provided on the side opposite to the support frame 2 and the frame 1, and the two ends of the guide rod 204 are fixedly connected to the support frame 2 and the frame 1 respectively, a connecting plate 205 is fixedly connected to the top of the cutting knife 201, a guide plate 206 is fixedly connected to the top of the connecting plate 205, and the guide plate 206 is an inverted "L"-shaped structure, and the guide plate 206 is slidably connected to the guide rod 204.

[0025] By setting the guide rod 204 and the guide plate 206, the movement trajectory of the cutting knife 201 can be limited so that it can only move along the direction of the guide rod 204, thereby ensuring the movement stability and straightness of the cutting knife 201 during the cutting process, thereby further improving the cutting accuracy and quality.

[0026] In this embodiment, the pushing mechanism includes a connecting frame 3, a first connecting rod 301, a second connecting rod 302, and a tension spring 303. The connecting frame 3 is arranged between the bottom of the support frame 2 and the top of the frame 1, and the connecting frame 3 is arranged at the bottom of the guide plate 206. One end of the first connecting rod 301 is rotatably connected to the first tensioning roller 103, the other end of the first connecting rod 301 is rotatably connected to one end of the connecting frame 3, one end of the second connecting rod 302 is rotatably connected to the second tensioning roller 104, the other end of the second connecting rod 302 is rotatably connected to the other end of the connecting frame 3, the first connecting rod 301 and the second connecting rod 302 are both arranged between the side surfaces of the first tensioning roller 103, the second tensioning roller 104 and the side surface of the frame 1, and the guide plate 206 The distance between the connecting frame 3 is smaller than the distance between the cutting knife 201 and the cloth 7 (it should be noted that the cloth 7 used for underwear can be made of any material such as spandex, polyester fiber, and nylon. Such materials have extremely high stretchability and elasticity, and have high shape recovery ability, so the fabric of the underwear is preferably spandex, polyester fiber, and nylon. In addition, the cloth 7 should be kept within its deformable range when stretched to avoid excessive stretching and prevent permanent deformation. Therefore, the distance that the cloth 7 is stretched will not be too large), and the tension spring 303 is arranged between the connecting frame 3 and the supporting frame 2, and the two ends of the tension spring 303 are fixedly connected to the supporting frame 2 and the connecting frame 3 respectively.

[0027] When the cutting knife 201 moves downward under the action of the cutting cylinder 202, the connecting plate 205 will move accordingly and drive the guide plate 206 to move downward. Since the distance between the guide plate 206 and the connecting frame 3 is smaller than the distance between the cutting knife 201 and the cloth 7, the guide plate 206 will first contact the top of the connecting frame 3, thereby causing the connecting frame 3 to move downward. When the connecting frame 3 moves downward, it will simultaneously drive the first connecting rod 301 and the second connecting rod 302 downward, and the tension spring 303 will be stretched. The movable groove 107 limits the freedom of the first tensioning roller 103 and the second tensioning roller 104, so that it can only move in the axial direction. Therefore, the first tensioning roller 103 and the second tensioning roller 104 will move away from each other under the action of the first connecting rod 301 and the second connecting rod 302, thereby stretching the cloth 7 between the first tensioning roller 103 and the second tensioning roller 104, and spreading the yarn to ensure the flatness of the cutting edge.

[0028] When the cutting knife 201 moves upward under the action of the cutting cylinder 202, the connecting plate 205 will move accordingly and drive the guide plate 206 to move upward. At the same time, the tension spring 303 will restore its deformation and drive the connecting frame 3 to move upward, thereby restoring the first tensioning roller 103 and the second tensioning roller 104 to their original positions.

[0029] The push mechanism in this embodiment has an ingenious structure, which can reduce energy consumption without an additional drive source, thereby saving energy costs. In addition, by utilizing the distance difference, the start-up sequence between the cutting mechanism and the push mechanism is realized, making the overall structure more concise, avoiding complex electrical, hydraulic or pneumatic systems, thereby reducing the failure rate and maintenance difficulty, and improving the reliability of the equipment.

[0030] Furthermore, a limiting rod 304 is fixedly connected to one side of the support frame 2 close to the connecting frame 3, and one end of the limiting rod 304 abuts against the top of the connecting frame 3 (abutting means contacting relationship), a sliding rod 305 is fixedly connected to the top of the connecting frame 3, and the sliding rod 305 is arranged inside the limiting rod 304 and is slidingly connected to the inner wall of the limiting rod 304, and a limiting plate 306 is fixedly connected to the side of the connecting plate 205, and the limiting plate 306 abuts against the bottom of the connecting frame 3.

[0031] When the telescopic rod of the cutting cylinder 202 is in the retracted state, the top of the connecting frame 3 contacts the limiting rod 304, which limits the freedom of the connecting frame 3 and prevents it from moving upwards during the conveying of the cloth 7. At the same time, the limiting plate 306 contacts the bottom of the connecting frame 3, limiting the downward freedom of the connecting frame 3, thereby preventing the first tensioning roller 103 and the second tensioning roller 104 from sliding during the conveying of the cloth 7.

[0032] When the telescopic rod of the cutting cylinder 202 is extended, the telescopic rod drives the connecting plate 205 to move downward, and the connecting plate 205 drives the limiting plate 306 downward, thereby providing space for the connecting frame 3 to move downward. At this time, the sliding rod 305 on the top of the connecting frame 3 will slide along the limiting rod 304 inside.

[0033] The limit rod 304 and the limit plate 306 can prevent the first tension roller 103 and the second tension roller 104 from shaking or shifting when the conveying mechanism conveys the cloth 7, thereby ensuring the stability of the conveying of the cloth 7, avoiding the distortion or wrinkles of the cloth 7, and further improving the smoothness and accuracy of the conveying of the cloth 7. Secondly, the limit rod 304 and the sliding rod 305 can also guide the connecting frame 3, preventing the connecting frame 3 from being offset or misaligned during the movement, and ensuring the stability of the movement of the pushing mechanism. At the same time, it can also ensure that the tension spring 303 is evenly stressed, thereby increasing the service life of the tension spring 303.

[0034] In this embodiment, a plurality of support blocks 4 are arranged at the bottom of the frame 1, and each support block 4 is arranged at the four corners of the workbench 203, and each support block 4 should be fixedly connected to the frame 1 or directly fixedly connected to the ground, which is not limited in this embodiment.

[0035] The lifting mechanism includes a pulley 401, a traction rope 402, and a plurality of elastic members 403 (the elastic members 403 can be cylindrical compression springs). The four corners of the bottom of the workbench 203 are fixedly connected with sliding rods 404, and each sliding rod 404 is fixedly connected to a limiting ring 405 on the side away from the workbench 203. Each sliding rod 404 is respectively connected to the corresponding support block 4 for sliding movement. One end of each elastic member 403 is fixedly connected to the limiting ring 405, and the other end of each elastic member 403 is fixedly connected to the top of the support block 4. The pulley 401 is arranged on the side of the support frame 2 and connected to the support frame 2 is rotatably connected, and the horizontal height of the pulley 401 is higher than the horizontal height of the guide plate 206. An extension plate 406 is provided on the side of the workbench 203. The outer surface of the traction rope 402 is set on the pulley 401. One end of the traction rope 402 is fixedly connected to the guide plate 206, and the other end of the traction rope 402 is fixedly connected to the extension plate 406. The distance between the surface of the workbench 203 and the cloth 7 is smaller than the distance between the cutting knife 201 and the cloth 7. It is worth noting that the distance between the surface of the workbench 203 and the cloth 7 is greater than the distance between the guide plate 206 and the connecting frame 3.

[0036] When the cutting knife 201 moves downward under the action of the cutting cylinder 202, the connecting plate 205 will also move downward under the action of the cylinder telescopic rod, and drive the guide plate 206 to move together. At the same time, the guide plate 206 drives one end of the traction rope 402 to move downward. Since the horizontal height of the pulley 401 is higher than the guide plate 206, the other end of the traction rope 402 will drive the extension plate 406 to move upward, thereby driving the workbench 203 to rise upward. The sliding rod 404 at the bottom of the workbench 203 moves upward synchronously with the rise of the workbench 203, and the sliding rod 404 drives the limit ring 405 upward, and the limit ring 405 compresses the elastic member 403. Since the distance between the surface of the workbench 203 and the cloth 7 is smaller than the distance between the cutting knife 201 and the cloth 7, the workbench 203 first contacts the bottom of the cloth 7, thereby providing support for the cloth 7.

[0037] When the cutting blade 201 is retracted, each elastic member 403 will restore its deformation, thereby restoring the workbench 203 to its original position.

[0038] The lifting mechanism in this embodiment is linked with the cutting mechanism, and the lifting action can be completed without an additional driving source, thereby saving energy costs and reducing equipment manufacturing and maintenance costs. In addition, the elastic member 403 plays a role of buffering and auxiliary reset, making the lifting process of the workbench 203 smooth and controllable.

[0039] Furthermore, receiving grooves 407 are provided on both sides of the workbench 203, and a third tensioning roller 408 is rotatably connected inside the receiving groove 407, and the top of the third tensioning roller 408 is flush with the surface level of the workbench 203. By providing the third tensioning roller 408, it is possible to avoid the damage of the cloth 7 due to the sharp corners when the workbench 203 contacts the bottom of the cloth 7, thereby improving the quality of the cloth 7 after cutting.

[0040] In this embodiment, a cutting table 5 is arranged on the workbench 203, and the position of the cutting table 5 corresponds to the position of the cutting knife 201. The cutting table 5 is provided with an adsorption component for adsorbing the cloth 7, and the adsorption component includes a negative pressure fan 501 and a negative pressure hose 502 (the negative pressure hose 502 should be reserved with sufficient length so that it can rise with the workbench 203). A vacuum groove is arranged inside the cutting table 5, and a plurality of vacuum adsorption holes 503 are arranged on the cutting table 5, and each vacuum adsorption hole 503 is connected to the inside of the vacuum groove, one end of the negative pressure hose 502 is connected to the negative pressure fan 501, and the other end of the negative pressure hose 502 is connected to the inside of the vacuum groove.

[0041] When the workbench 203 contacts the bottom of the cloth 7 under the action of the lifting mechanism, the negative pressure fan 501 is started. The negative pressure fan 501 will make the inside of the vacuum tank in a vacuum state through the negative pressure hose 502, and the vacuum adsorption hole 503 will produce an air pressure difference with the outside world, so that the cloth 7 is firmly adsorbed on the surface of the cutting table 5, ensuring that the cloth 7 is fixed during the cutting process, avoiding the movement of the cloth 7 due to external force, and greatly improving the cutting accuracy and quality.

[0042] Secondly, the adsorption component can also automatically unload the cut fabric when the telescopic rod of the cutting cylinder 202 is retracted, thereby greatly improving the work efficiency of the staff (the negative pressure fan 501 should continue to work during unloading).

[0043] In this embodiment, a feeding mechanism for feeding the cloth 7 is also included, and the feeding mechanism includes a feeding cylinder 6, a collecting box 601, a nozzle 602, and an air supply source connected to each nozzle 602 (the air supply source can be an air pump or any other device that can convey gas to the nozzle 602, which is a prior art well known to those skilled in the art, so this embodiment does not limit this), the cutting table 5 is rotatably connected to the workbench 203, a support plate 603 is fixedly connected to the bottom of the workbench 203, the feeding cylinder 6 is rotatably connected to the support plate 603, the telescopic rod of the feeding cylinder 6 is rotatably connected to the bottom of the cutting table 5, an air supply plate 604 is provided on the top of the support block 4, the nozzle 602 is arranged on the side of the air supply plate 604 facing the cutting table 5, and the nozzle 602 is inclined, and the collecting box 601 is arranged on the side of the cutting table 5 away from the nozzle 602.

[0044] When the fabric is cut, the cut cloth 7 will adhere to the surface of the cutting table 5 under the action of the adsorption component. At this time, when the workbench 203 contacts the top of the support block 4 under the action of the lifting mechanism, the negative pressure fan 501 is turned off, the unloading cylinder 6 is started and its telescopic rod is retracted. Then, the cutting table 5 rotates downward, and the air supply source is used to supply air to the nozzle 602, so that the nozzle 602 blows air to the cloth 7 on the cutting table 5, helping the cloth 7 to fall into the collection box 601, thereby improving the unloading efficiency and automation of the cloth 7, and then improving the work efficiency of the staff.

[0045] Working principle: When the fabric is transported to a certain length, the cutting cylinder 202 is started, and the telescopic rod of the cutting cylinder 202 moves downward, which drives the connecting plate 205 to move, and the cutting knife 201 moves downward with the connecting plate 205, and drives the guide plate 206 to move downward. Since the distance between the guide plate 206 and the connecting frame 3 is smaller than the distance between the cutting knife 201 and the fabric 7, the guide plate 206 will first contact the top of the connecting frame 3, thereby moving the connecting frame 3 downward. When the connecting frame 3 moves downward, it will simultaneously drive the first connecting rod 301 and the second connecting rod 302 downward, and the tension spring 303 will be stretched. The movable groove 107 limits the freedom of the first tensioning roller 103 and the second tensioning roller 104, so that they can only move in the axial direction. Therefore, the first tensioning roller 103 and the second tensioning roller 104 will move away from each other under the action of the first connecting rod 301 and the second connecting rod 302, thereby stretching the cloth 7 between the first tensioning roller 103 and the second tensioning roller 104 and spreading the yarn to ensure the flatness of the cutting edge.

[0046] At the same time, the guide plate 206 drives one end of the traction rope 402 to move downward. Since the horizontal height of the pulley 401 is higher than the guide plate 206, the other end of the traction rope 402 will drive the extension plate 406 to move upward, thereby driving the workbench 203 to rise upward. The sliding rod 404 at the bottom of the workbench 203 moves upward synchronously with the rise of the workbench 203, and the sliding rod 404 drives the limit ring 405 upward, and the limit ring 405 compresses the elastic member 403. Since the distance between the surface of the workbench 203 and the cloth 7 is smaller than the distance between the cutting knife 201 and the cloth 7, the workbench 203 first contacts the bottom of the cloth 7, thereby providing support for the cloth 7.

[0047] When the fabric is cut, the cut cloth 7 will adhere to the surface of the cutting table 5 under the action of the adsorption component. At this time, when the workbench 203 contacts the top of the support block 4 under the action of the lifting mechanism, the negative pressure fan 501 is turned off, the unloading cylinder 6 is started and its telescopic rod is retracted. Then, the cutting table 5 rotates downward, and the air supply source is used to supply air to the nozzle 602, so that the nozzle 602 blows air to the cloth 7 on the cutting table 5, helping the cloth 7 to fall into the collection box 601, thereby improving the unloading efficiency and automation of the cloth 7, and then improving the work efficiency of the staff.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
