Description

Technical Field

[0001] The utility model relates to the technical field of underwear bonding machines, in particular to a traceless underwear bonding machine capable of eliminating cutting deviation. Background Art

[0002] An underwear bonding machine is an automated device specifically designed for underwear production. It can precisely bond the various parts of underwear together without the need for traditional sewing threads, thus achieving a seamless effect for the underwear. The machine heats and applies a certain amount of pressure to quickly melt and bond the bonding parts of the underwear together. Some advanced underwear bonding machines also use ultrasonic technology, which uses the energy generated by high-frequency vibrations to achieve bonding, which is usually more efficient and environmentally friendly. The underwear bonding machine also has a cutting component that cuts the fabric. When cutting the fabric, the cutting knife is prone to offset when cutting the material, which affects the cutting effect of the fabric.

[0003] Chinese patent CN218354716U discloses an adjustment mechanism for the cutter of a seamless underwear gluing and bonding machine, including a base, a gluing machine, a workbench and a lower cutter, wherein the base is installed at the bottom of the gluing machine, a workbench is installed above the base, a lower cutter is installed on one side of the workbench through an assembly seat, a horizontal plate is welded on the surface of the gluing machine, an extended threaded column is spirally plugged into the surface of the horizontal plate, the plug-in end of the extended threaded column is movably connected to the bottom plate through an axle seat, a guide rod A is symmetrically installed on the upper surface of the bottom plate, the lower surface of the bottom plate is fixedly connected to the fixed end of the electric push rod, the transmission output end of the electric push rod is transmission-connected to the knife seat, and the upper cutter is detachably connected below the knife seat. This patent rotates the threaded column, and the bottom plate drives the upper cutter to adjust its height, and the guide rod A slides relative to the horizontal plate to make the upper cutter move smoothly without offset.

[0004] The prior art adjusts the height of the cutter by rotating the threaded column, and some devices are also provided with an adjustment mechanism along the X-axis and the Y-axis on the upper cutter. However, when cutting cloth, the underwear bonding machine can only adjust the upper cutter, while the lower cutter is fixed. Since the position of the lower cutter is fixed, it is difficult to adapt to the cutting requirements of cloths of different sizes and shapes, which often leads to the problem of cutting deviation, affecting the yield and overall quality of the underwear.

[0026] The lower cutting blade body 1261 is further equipped with a first lower cutting blade adjustment mechanism 1262 and a second lower cutting blade adjustment mechanism 1263, which work together to achieve precise adjustment of the position of the lower cutting blade body 1261. Through this design, no matter where the upper cutting blade body 1251 is, the lower cutting blade body 1261 can always be ensured to be directly below the upper cutting blade body 1251. This feature significantly improves the cutting accuracy and effectively eliminates the problem of cutting deviation.

[0027] refer to Figure 6As shown, the first lower cutting knife adjustment mechanism 1262 includes a support frame 12621 fixed on the top of the base plate 121, the first lower cutting knife adjustment mechanism 1262 also includes a fourth lead screw 12623 rotatably arranged along the length direction of the support frame 12621, the first lower cutting knife adjustment mechanism 1262 also includes a fourth rotating drive member 12622 fixed on the outside of the support frame 12621, the output end of the fourth rotating drive member 12622 is fixedly connected to the fourth lead screw 12623, and the support frame 12621 is also provided with two third sliding rods 12624 arranged along its length direction. The first lower cutting knife adjustment mechanism 1262 is used to drive the second lower cutting knife adjustment mechanism 1263 to move back and forth. The second lower cutting knife adjustment mechanism 1263 includes a sliding frame 12631 threadedly connected to the fourth lead screw 12623 in the first lower cutting knife adjustment mechanism 1262, the sliding frame 12631 is slidably connected to the third slide bar 12624 in the first lower cutting knife adjustment mechanism 1262, a fifth rotating driving member 12632 is fixed to the outside of the sliding frame 12631, the output end of the fifth rotating driving member 12632 is slidably connected to the fifth lead screw 12633, a fourth slide bar 12634 is also provided in the sliding frame 12631, the fourth slide bar 12634 is slidably connected to the lower cutting knife body 1261, and the fifth lead screw 12633 is threadedly connected to the lower cutting knife body 1261.

[0028] When the fourth rotary drive member 12622 is working, it drives the fourth lead screw 12623 to rotate, thereby causing the sliding frame 12631 (i.e., the second lower cutting knife adjustment mechanism 1263) to move linearly along the length direction of the third slide bar 12624. When the sliding frame 12631 reaches the predetermined position, the fifth rotary drive member 12632 starts to work, driving the fifth lead screw 12633 to rotate. Since the fifth lead screw 12633 is connected to the lower cutting knife body 1261 through a thread, the lower cutting knife body 1261 moves linearly along the length direction of the fifth lead screw 12633. Through such a two-stage adjustment mechanism, the position of the lower cutting knife body 1261 can be accurately controlled, thereby ensuring the accuracy of cutting.

[0029] refer to Figure 2-Figure 5As shown, the cutting assembly 12 also includes a lifting mechanism 123 disposed on the mounting plate 122, a lifting plate 124 capable of moving up and down is disposed on the lifting mechanism 123, and an upper cutting knife assembly 125 is disposed on the lifting plate 124. The upper cutting knife assembly 125 includes an upper cutting knife height adjustment mechanism 1254 for driving an upper cutting knife body 1251, a first upper cutting knife adjustment mechanism 1252, and a second upper cutting knife adjustment mechanism 1253 to move up and down, the upper cutting knife height adjustment mechanism 1254 includes a third lead screw 12542 vertically disposed in the lifting plate 124, the third lead screw 12542 is provided with a driven gear 12543 through a thread sleeve, the upper cutting knife height adjustment mechanism 1254 also includes a third rotating driving member 12541 fixed to the top of the lifting plate 124, the output end of the third rotating driving member 12541 extends into the lifting plate 124 and is fixed with a driving gear 12544, and the driving gear 12544 and the driven gear 12543 are meshed with each other.

[0030] When the height of the upper cutting blade assembly 125 needs to be adjusted, the third rotating driving member 12541 starts to work, driving the driving gear 12544 to rotate. The driving gear 12544 and the driven gear 12543 are meshed with each other, so the driven gear 12543 will also rotate. Since the driven gear 12543 is arranged on the third lead screw 12542 through a threaded sleeve, when the driven gear 12543 rotates, it will drive the third lead screw 12542 to move up and down. Thereby, the height adjustment of the upper cutting blade assembly 125 is realized.

[0031] The first upper cutting knife adjustment mechanism 1252 includes a support member 12524 that can move up and down on the lifting plate 124, the top of the support member 12524 is connected to the third lead screw 12542, a first lead screw 12523 is rotatably arranged in the support member 12524, a first rotating driving member 12521 is fixed to the outside of the support member 12524, the output end of the first rotating driving member 12521 is fixedly connected to the first lead screw 12523, and a first sliding rod 12522 for guiding the second upper cutting knife adjustment mechanism 1253 is also arranged in the support member 12524.

[0032] The second upper cutting knife adjustment mechanism 1253 includes a first slide 12531, the first slide 12531 is slidably connected to the first slide rod 12522, the first slide 12531 is threadedly connected to the first lead screw 12523, a second lead screw 12534 is rotatably arranged in the first slide 12531, a second rotating driving member 12532 is fixed to the outside of the first slide 12531, the output end of the second rotating driving member 12532 is fixedly connected to the second lead screw 12534, a second slide rod 12533 ​​for guiding the upper cutting knife body 1251 is also arranged in the first slide 12531, and the upper cutting knife body 1251 is threadedly connected to the second lead screw 12534.

[0033] When the first rotating driving member 12521 is working, the first rotating driving member 12521 will drive the first lead screw 12523 to rotate. Since the first slide 12531 is connected to the first lead screw 12523 by threads and is slidably connected to the first slide bar 12522, the first slide 12531 will move horizontally along the length direction of the first lead screw 12523 and the first slide bar 12522. When the second rotating driving member 12532 is working, the second rotating driving member 12532 drives the second lead screw 12534 to rotate. Since the upper cutting knife body 1251 is connected to the second lead screw 12534 by threads and is slidably connected to the second slide bar 12533, the upper cutting knife body 1251 is moved. Through such a two-stage adjustment mechanism, the position adjustment of the upper cutting knife body 1251 can be achieved.

[0034] The detection component 127 includes a support block 1271 fixed on the support member 12524 in the upper cutting knife assembly 125, and a first adjusting rod 1272 is hinged on the support block 1271. The detection component 127 also includes a second adjusting rod 1273, one end of the second adjusting rod 1273 is hinged to the first adjusting rod 1272, and the other end of the second adjusting rod 1273 is hinged to a detection camera 1274.

[0035] By adjusting the relative angle between the first adjustment rod 1272 and the second adjustment rod 1273, the position and angle of the detection camera 1274 can be changed. Once the detection camera 1274 is adjusted to a suitable position and angle, the detection camera 1274 can begin to capture images or video information during the cutting process. Such information can be used to monitor cutting quality, detect cutting errors, or perform other related analysis and processing.

[0036] The main function of the detection component 127 is to detect the relative position relationship between the upper cutting blade body 1251 and the lower cutting blade body 1261. By feeding back this information in real time, the detection component 127 helps to further improve the adjustment accuracy of the upper cutting blade body 1251 and the lower cutting blade body 1261, thereby ensuring that the cutting accuracy of the cloth reaches a higher level.

[0037] Working principle: When the device is in use, first manually adjust the first adjustment rod 1272 and the second adjustment rod 1273 to position the detection camera 1274 to the best viewing angle that can accurately capture the relative position of the upper cutting knife body 1251 and the lower cutting knife body 1261. Next, by starting the first rotating drive member 12521, the first lead screw 12523 of the first rotating drive member 12521 rotates, thereby driving the first sliding member 12531 to move, thereby achieving preliminary position adjustment. Subsequently, the second rotating drive member 12532 is started, and the second rotating drive member 12532 drives the second lead screw 12534 to rotate, thereby accurately controlling the position of the upper cutting knife body 1251. In order to adjust the position of the lower cutting knife body 1261, the fourth rotating drive member 12622 is started, and the fourth rotating drive member 12622 drives the fourth lead screw 12623 to rotate, thereby driving the sliding frame 12631 to move. Subsequently, the fifth rotary drive member 12632 is started, and the fifth rotary drive member 12632 drives the fifth lead screw 12633 to rotate, so as to achieve precise fine adjustment of the position of the lower cutting knife body 1261. After confirming that the relative positions of the upper cutting knife body 1251 and the lower cutting knife body 1261 are correct, the upper cutting knife body 1251 is lowered to a position close to the cloth by using the lifting mechanism 123. Prior to this, the relative positions of the upper cutting knife body 1251 and the lower cutting knife body 1261 have been preliminarily detected by using the detection camera 1274 to ensure the cutting accuracy. After the cloth is placed between the upper cutting knife body 1251 and the lower cutting knife body 1261, the upper cutting knife body 1251 is firstly lowered by the lifting mechanism 123 to contact and slightly press the cloth. Then, the third rotary driving member 12541 is started, the third rotary driving member 12541 drives the driving gear 12544 to rotate, and the driving gear 12544 then drives the driven gear 12543 to rotate, so that the third lead screw 12542 and the upper cutting knife body 1251 thereon are continuously pressed down until the cloth is cut, thereby ensuring the accuracy and stability of cutting.
