Description

Technical Field

[0001] The invention relates to the technical field of clothing hole opening, in particular to a clothing buttonhole opening machine with an anti-wrinkle function. Background Art

[0002] "Buttonhole making" refers to the process of making small holes on clothing for passing buttons. Buttonholes are usually used in collars, cuffs, front lapels and other parts to facilitate the wearer to put on and take off clothes. There are many ways to make buttonholes, which can be roughly divided into two ways: manual and machine. The machine usually uses a buttonhole making machine, also known as a buttonhole machine or a keyhole machine. It is a sewing device specially used to make buttonholes (i.e. small holes for buttons to pass through) on clothing, curtains, canvas or other fabrics. Most of the existing buttonhole making machines set the feed amount of the tool through an electric push rod, and then start to make buttonholes on the clothing. However, after long-term use, the wear of the internal parts of the electric push rod and the failure of the control system can easily cause the feed amount of the electric push rod to exceed the set value. At this time, the tool will collide and squeeze with the bottom placement table. The existing buttonhole making machine cannot form emergency protection for the tool when this happens, resulting in the tool continuously colliding and squeezing the placement table when the tool makes buttonholes on the clothing. The tool will be damaged and broken due to the squeezing force with the placement table, causing the tool to be unable to continue punching holes in the clothing. Summary of the invention

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] After long-term use, the existing buttonhole making machine will easily cause the wear of the internal parts of the electric push rod and the failure of the control system, which will easily cause the feed amount of the electric push rod to exceed the set value. When this happens, the existing buttonhole making machine cannot form emergency protection for the tool, resulting in the tool continuously colliding and squeezing the placement table when the tool is making buttonholes on clothing. The tool is easily damaged and broken due to the squeezing force with the placement table, making it impossible for the tool to continue punching holes in the clothing.

[0032] Example 1: A clothing buttonhole machine with anti-wrinkle function, compared with Figure 1-Figure 4As shown, it includes a support base 1, a support shell 2 is fixedly connected to the left side of the upper plane of the support base 1, a rotating inner shell 3 is rotatably connected to the inside of the support shell 2, two sliding shells 4 symmetrically distributed in the center are slidably connected to the inside of the rotating inner shell 3, the two sliding shells 4 symmetrically distributed in the center are both located outside the support shell 2, the tops of the two sliding shells 4 symmetrically distributed in the center are both fixedly connected to a first electric push rod 5 through a connecting piece, the telescopic end of the first electric push rod 5 is fixedly connected to a first elastic push rod 6, the fixed part of the first elastic push rod 6 is filled with hydraulic oil, the telescopic end of the first elastic push rod 6 is fixedly connected to a punch 7, the telescopic end of the first electric push rod 5 is connected to the first elastic push rod 6 through the first An elastic push rod 6 drives the adjacent punching knife 7 to feed downward to open buttonholes on clothing. The bottom of the rotating inner shell 3 is fixedly connected with two second elastic push rods 8 distributed symmetrically in the center. The fixed part of the second elastic push rod 8 is filled with hydraulic oil. The top of the sliding shell 4 is provided with a blind hole. The telescopic end of the second elastic push rod 8 is limitedly matched with the blind hole on the adjacent sliding shell 4. The bottom of the rotating inner shell 3 is fixedly connected with two pressure valves 10 distributed symmetrically in the center (when the pressure in the system exceeds the preset value, the pressure valve will automatically open and release part of the medium, such as gas or liquid, to reduce the pressure in the system. Once the pressure drops to a safe range, the pressure valve will close again). The inlet ends of the two pressure valves 10 symmetrically distributed on the center are respectively fixedly connected to the fixed parts of the adjacent first elastic push rods 6 and are connected with the first connecting pipe 9. The first connecting pipe 9 is filled with hydraulic oil. The pressure valve 10 is used to detect whether the pressure value of the hydraulic oil in the fixed part of the first elastic push rod 6 exceeds the preset value of the pressure valve 10. The outlet ends of the two pressure valves 10 symmetrically distributed on the center are respectively connected to the fixed parts of the adjacent second elastic push rods 8. When the hydraulic oil in the fixed part of the first elastic push rod 6 exceeds the preset value of the pressure valve 10, the hydraulic oil in the fixed part of the first elastic push rod 6 enters the fixed part of the adjacent second elastic push rod 8 along the first connecting pipe 9. A first elastic element 11 is arranged between the two sliding shells 4 and the rotating inner shell 3. The first elastic element 11 is a tension spring, and its initial state is a stretched state, which is used to drive the adjacent sliding shells 4 to move upward along the rotating inner shell 3. Two self-locking components symmetrically distributed on the center are arranged in the rotating inner shell 3 and are used to lock the adjacent sliding shells 4. A fixing component for preventing clothes from wrinkling is arranged on the supporting base 1. The extrusion force of the punching knife 7 is detected by the first elastic push rod 6, and the telescopic end of the second elastic push rod 8 is driven to release the limit on the sliding shell 4, so that the first elastic element 11 pulls the sliding shell 4 to slide upward, so that the punching knife 7 reduces the extrusion and avoids further damage to the punching knife 7.

[0033] Comparison Figure 3 and Figure 5As shown, the self-locking component includes a sawtooth rod 201, which is fixedly connected to the upper part of the rotating inner shell 3, and the sliding shell 4 is slidably connected to a limiting shaft 202 on one side close to the adjacent sawtooth rod 201. The sawtooth rod 201 is limitedly matched with the adjacent limiting shaft 202, and two second elastic elements 203 distributed in a mirror image are arranged between the limiting shaft 202 and the adjacent sliding shell 4. The second elastic element 203 is a spring, and the second elastic element 203 is used to drive the adjacent limiting shaft 202 to reset. A switching component for switching the punching knife 7 is arranged in the support shell 2, and the limiting shaft 202 is reset to fit with the adjacent sawtooth rod 201, so that the sawtooth rod 201 locks the adjacent sliding shell 4 through the limiting shaft 202, so that the sliding shell 4 is quickly stabilized, and the sliding shell 4 is prevented from shaking due to the gravity of the sliding shell 4 itself, which pulls the adjacent first elastic element 11 again.

[0034] Comparison Figure 2 and Figure 3 As shown, the switching component includes a servo motor 301, the servo motor 301 is fixedly connected to the inside of the supporting shell 2, the output shaft of the servo motor 301 is fixedly connected to the first pulley 302, the top of the rotating inner shell 3 is fixedly connected to the second pulley 303, a belt is wound between the first pulley 302 and the second pulley 303, the output shaft of the servo motor 301 drives the rotating inner shell 3 to rotate through the first pulley 302, the second pulley 303 and the belt therebetween, two mirror-distributed pressure sensors 304 are fixedly connected to the rotating inner shell 3, and the two mirror-distributed pressure sensors 304 are respectively connected to the third pressure sensors 304 disposed between the adjacent sliding shells 4. The elastic element 305, the third elastic element 305 is a spring, which is used to apply pressure to the adjacent pressure sensors 304. The pressure sensors 304 distributed symmetrically around the center are all electrically connected to the servo motor 301. After the pressure sensor 304 senses the pressure, it sends a signal to the servo motor 301 to rotate it 180°. The elastic force of the first elastic element 11 is greater than the sum of the elastic force of the adjacent second elastic element 203, the elastic force of the adjacent third elastic element 305 and the gravity of the adjacent sliding shell 4 and its internal parts, ensuring that the first elastic element 11 can overcome the resistance of the two adjacent second elastic elements 203 and the third elastic element 305, and drive the sliding shell 4 to move upward.

[0035] Comparison Figure 1 , Figure 6 and Figure 7As shown, the fixing component includes a placing table 401, which is slidably connected to the supporting base 1 through an electric slide rail. The electric slide rail on the supporting base 1 drives the placing table 401 to move synchronously, and the placing table 401 drives the clothes thereon to move and change the position of the buttonholes. A pressing plate 402 is hinged on the left side of the placing table 401, and a handle 403 is fixedly connected to the rear side of the pressing plate 402. The staff drives the pressing plate 402 to press the clothes to fix them through the handle 403. A limiting component for locking the handle 403 is arranged on the left side of the placing table 401, and the remaining sides of the placing table 401 are all provided with leveling components for leveling the clothes.

[0036] Comparison Figure 7 As shown, the limiting assembly includes a clamping shaft 404, which is slidably connected to the rear of the left side of the placing platform 401, and a fourth elastic element 405 is arranged between the clamping shaft 404 and the placing platform 401. The fourth elastic element 405 is a tension spring, and the fourth elastic element 405 is used to drive the clamping shaft 404 to reset. A through hole is arranged on the handle 403, and the clamping shaft 404 is limitedly matched with the through hole on the handle 403. After the clothing is fixed by the pressing plate 402, the pressing plate 402 is locked by inserting the clamping shaft 404 into the through hole on the handle 403.

[0037] Comparison Figure 8 As shown, the leveling assembly includes a second electric push rod 501, which is fixedly connected to the adjacent side of the placement table 401, and the telescopic end of the second electric push rod 501 is fixedly connected to the first rack 502. The placement table 401 is slidably connected to two sliders 503 distributed in a mirror image, and the two sliders 503 distributed in a mirror image are hinged together with a pressing shaft 504. The pressing shaft 504 is fixedly connected to uniformly distributed rubber blocks for increasing the friction between the pressing shaft 504 and the clothing. The pressing shaft 504 is fixedly connected to one end of the pressing shaft 504 close to the adjacent second electric push rod 501 with teeth of a fan-shaped array, and the teeth of the fan-shaped array are all connected to the adjacent first rack 502. 02 are engaged, the sliding resistance of the slider 503 along the placement table 401 is greater than the rotational resistance of the pressing shaft 504 along the two adjacent sliders 503, which is used to make the first rack 502 drive the adjacent pressing shaft 504 to rotate along the adjacent slider 503 first, and then the first rack 502 pulls the adjacent slider 503 to slide along the placement table 401, the telescopic end of the second electric push rod 501 drives the pressing shaft 504 to contact the clothing through the first rack 502 and the teeth of the fan-shaped array, and then the telescopic end of the second electric push rod 501 drives the two sliders 503 to move along the placement table 401 through the first rack 502, so that the clothing is pulled and flattened.

[0038] When the staff needs to make buttonholes on the clothing, the staff places the clothing on the placement table 401, flattens the buttonholes of the clothing, and then turns the handle 403 and pulls the clamping shaft 404 to make it slide along the placement table 401. At the same time, the fourth elastic element 405 is stretched, and the handle 403 drives the pressing plate 402 to rotate, so that the pressing plate 402 contacts the clothing and presses it to fix it. At this time, the through hole on the handle 403 rotates to the clamping shaft 404, and the clamping shaft 404 is released at this time. The fourth elastic element 405 resets and drives the clamping shaft 404 to slide into the through hole on the handle 403, so that the clamping shaft 404 limits the handle 403. At this time, the punching position of the clothing is fixed.

[0039] When the punching position of the clothing is fixed, the three second electric push rods 501 are turned on, and the telescopic ends of the second electric push rods 501 drive the first rack 502 thereon to move, and the first rack 502 drives the adjacent pressing shafts 504 to rotate and contact the clothing through the teeth of the fan-shaped array, so that the three pressing shafts 504 press the clothing, and then the telescopic ends of the second electric push rods 501 continue to drive the first rack 502 thereon to move. At this time, the adjacent pressing shafts 504 cannot continue to rotate due to contact with the clothing. At this time, the first rack 502 drives the two adjacent mirror-distributed sliders 503 to slide along the placement table 401 through the adjacent pressing shafts 504. At this time, the pressing shafts 504 press the clothing and drive it to move synchronously, so that the entire clothing is driven by the three pressing shafts 504 to smooth out the wrinkles on it, and then the three second electric push rods 501 are closed, and the clothing is fixed.

[0040] When the clothing is fixed, the first electric push rod 5 is turned on, and the telescopic end of the first electric push rod 5 drives the first elastic push rod 6 to move downward, and the telescopic end of the first elastic push rod 6 drives the adjacent punching knife 7 to move downward, until the punching knife 7 contacts the clothing, and the punching knife 7 opens buttonholes on the clothing. When the punching knife 7 has completed opening holes in the clothing, the telescopic end of the first electric push rod 5 moves upward, and at the same time, the punching knife 7 is driven to reset through the first elastic push rod 6, and then the electric slide rail on the supporting base 1 drives the placement table 401 to move, and the buttonhole opening position of the clothing is changed, and then the above steps are repeated until the buttonhole opening of the clothing is completed, and then the three second electric push rods 501 are turned on, and the telescopic ends of the second electric push rods 501 are reset. The telescopic end of the second electric push rod 501 drives the first rack 502 thereon to reset, and the first rack 502 drives the pressing shaft 504 to separate from the clothing through the teeth of the adjacent annular array. When the pressing shaft 504 rotates to the limit state, the first rack 502 pushes the two adjacent mirror-distributed sliders 503 to reset along the placement table 401. Then the staff pulls the clamping shaft 404, and the fourth elastic element 405 is stretched to separate the clamping shaft 404 from the through hole on the handle 403. Then the handle 403 is turned to release the fixing of the pressing plate 402 on the clothing, and at the same time loosens the clamping shaft 404 to drive it to reset, and then the clothing with buttonholes opened is taken down, and this cycle is repeated until the buttonholes are opened.

[0041] When the first electric push rod 5 is used for a long time, the feeding amount is very likely to increase. When the feeding amount of the telescopic end of the first electric push rod 5 increases, the telescopic end of the first electric push rod 5 squeezes the placement table 401 through the punch 7 of the first elastic push rod 6, and a huge squeezing force is generated between the punch 7 and the placement table 401. The squeezing force drives the telescopic end of the first elastic push rod 6 to slide along its fixed part through the punch 7. At this time, the hydraulic oil in the fixed part of the first elastic push rod 6 breaks through the limit of the adjacent pressure valve 10 due to the squeezing force, so that the hydraulic oil in the fixed part of the first elastic push rod 6 slides along the adjacent The first connecting pipe 9 enters the fixed part of the second elastic push rod 8, and the hydraulic oil in the fixed part of the second elastic push rod 8 pushes its telescopic end to separate from the blind hole on the adjacent sliding shell 4. At this time, the first elastic element 11 is reset and pulls the adjacent sliding shell 4 to move upward along the rotating inner shell 3, so that the sliding shell 4 drives the first electric push rod 5 and the punching knife 7 inside it to move upward synchronously, so that the punching knife 7 is separated from the placement table 401, and the punching knife 7 is protected, so as to prevent the first electric push rod 5 from driving the punching knife 7 to further squeeze the placement table 401, causing further damage to the punching knife 7.

[0042] When the sliding shell 4 slides upward along the rotating inner shell 3, the sliding shell 4 drives the outer limiting shaft 202 to move upward synchronously, and the limiting shaft 202 contacts the adjacent serrated rod 201, so that the serrated rod 201 squeezes the adjacent limiting shaft 202, so that the limiting shaft 202 slides along the sliding shell 4 under the squeezing force, and the two second elastic elements 203 distributed in a mirror image are compressed. When the first elastic element 11 recovers to the unstretched state, the sliding shell 4 stops moving. At this time, the two second elastic elements 203 distributed in a mirror image are reset, and drive the adjacent limiting shaft 202 to reset and fit the adjacent serrated rod 201, so that the serrated rod 201 locks the adjacent sliding shell 4 through the limiting shaft 202, so that the sliding shell 4 is quickly stabilized, and the sliding shell 4 is prevented from shaking by pulling the first elastic element 11 again due to its own gravity.

[0043] When the first elastic element 11 pulls the adjacent sliding shell 4 to slide upward, the adjacent pressure sensor 304 senses the pressure change, and the pressure sensor 304 sends a signal to the servo motor 301. After the servo motor 301 receives the signal, the output shaft of the servo motor 301 drives the first pulley 302 to rotate, and the first pulley 302 drives the second pulley 303 to rotate synchronously through the belt, and the second pulley 303 drives the rotating inner shell 3 to rotate 180°, and rotates the other sliding shell 4 to the punching position, and then continues to open buttonholes on the clothing, and so on until the buttonhole opening of the clothing is completed, by switching the punching knife 7 that has been squeezed and damaged by the placement table 401, the buttonhole opening of the clothing is continued, to avoid the punching knife 7 being damaged and causing the buttonhole opening work of the clothing to be unable to proceed, thereby reducing the buttonhole opening efficiency of the clothing.

The telescopic end of the first electric push rod 5 drives the punching knife 7 to move through the first elastic push rod 6 on its telescopic end, and the punching knife 7 drives the adjacent push cylinder 601 to move, so that the push cylinder 601 slides along the piston shaft 602, and the volume of the closed cavity formed by the cooperation of the two is changed. The punching knife 7 is slidably connected with a piston shaft fixedly connected to the adjacent sliding shell 4. A sliding ring 603 is provided with a second connecting pipe 604 fixedly connected between the sliding ring 603 and the push cylinder 601, four ventilation channels 605 in a circular array are arranged in the sliding ring 603, the sliding ring 603 is connected with the closed cavity through the second connecting pipe 604, the sliding ring 603 is connected with the punching knife 7 through the four ventilation channels 605 in the circular array, an opening component for opening the closed cavity is arranged at the bottom of the push cylinder 601, the external airflow is drawn into the closed cavity by the downward sliding of the push cylinder 601 along the piston shaft 602, the upward sliding of the push cylinder 601 along the piston shaft 602 makes the gas in the closed cavity enter the punching knife 7 along the second connecting pipe 604 and the four ventilation channels 605 in the circular array, and be discharged to the outside.

The two groups of teeth distributed in a mirror image are respectively located at both ends of the fixed rod, and are used to rotate the rotating shaft 701 when the adjacent punching knife 7 opens buttonholes on clothing, and when the punching knife 7 is reset to an initial height, the second rack 703 is in transmission cooperation with the gear 702, and in the initial state, the gear 702 is located on the teeth at the top of the adjacent second rack 703, and at this time, the closed cavity formed by the communicating hole 705, the push cylinder 601 and the piston shaft 602 is in a communicating state, and a fifth elastic element is arranged between the rotating shaft 701 and the push cylinder 601. 704, the fifth elastic element 704 is a torsion spring, which is used to maintain the stability of the rotating shaft 701. The fifth elastic element 704 is initially in a torsion state. A connecting hole 705 is provided on the rotating shaft 701. The connecting hole 705 is connected and coordinated with the closed cavity formed by the push cylinder 601 and the piston shaft 602. The connecting hole 705 is connected and coordinated with the second connecting pipe 604. The rotating shaft 701 drives the connecting hole 705 to rotate synchronously, and controls the connection state of the closed cavity formed by the push cylinder 601 and the piston shaft 602. By adjusting the volume of the closed cavity formed by the push cylinder 601 and the piston shaft 602, the internal gas forms negative pressure and high pressure. The negative pressure draws the clothing residue into the inside of the punch, and the high pressure flushes the clothing residue out of the punch, so as to avoid the clothing residue remaining in the buttonholes of the clothes and the punch, thereby reducing the quality of the buttonholes of the clothes.

[0046] When the telescopic end of the first electric push rod 5 drives the punching knife 7 to open the buttonhole of the clothing through the first elastic push rod 6, the clothing residue at the opened buttonhole is very easy to adhere to the buttonhole of the clothes, resulting in the need for subsequent staff to manually button it out, which greatly reduces the efficiency of opening the buttonhole of the clothing. When the telescopic end of the first electric push rod 5 drives the punching knife 7 to open the buttonhole of the clothing through the first elastic push rod 6, the punching knife 7 drives the adjacent push cylinder 601 to move downward synchronously, and the push cylinder 601 slides downward along the adjacent piston shaft 602. At this time, the push cylinder 601 01 drives the rotating shaft 701 at the bottom to move synchronously, and the rotating shaft 701 drives the gear 702 thereon to move downward, and the gear 702 moves downward along the tooth group at the top of the second rack 703, so that the rotation of the gear 702 drives the rotating shaft 701 to rotate synchronously, and the rotation of the rotating shaft 701 drives the connecting hole 705 thereon to rotate, so that the rotating shaft 701 cuts off the connection between the connecting hole 705 and the closed cavity and the second connecting pipe 604, and at the same time the fifth elastic element 704 is gradually reset, so that the gear 702 and the second The top teeth group on the rack 703 separates, and then the push cylinder 601 continues to move downward with the punching knife 7. At this time, the push cylinder 601 slides along the piston shaft 602 to increase the volume of the closed cavity, so that the gas in the closed cavity forms a negative pressure, and this continues until the punching knife 7 contacts the clothing and starts to open the buttonhole. The gear 702 contacts the bottom teeth group on the second rack 703, and then the gear 702 moves along the second rack 703, so that the gear 702 drives the rotating shaft 701 to rotate, and at the same time the fifth elastic element 704 is twisted. The rotating shaft 701 drives the connecting hole 705 to rotate so that the closed cavity is connected with the second connecting pipe 604. At this time, the negative pressure in the closed cavity draws the clothing residues into the inside of the punching knife 7 along the second connecting pipe 604 and the annular array of ventilation channels 605. By increasing the volume of the closed cavity formed by the push cylinder 601 and the piston shaft 602, the internal gas forms a negative pressure, and the clothing residues are drawn into the inside of the punching knife 7 by the negative pressure, so as to avoid the clothing residues from remaining in the buttonholes of the clothes and reduce the speed of opening the buttonholes of the clothes.

[0047] After the clothing residue is extracted into the inside of the punch 7, the gas pressure in the closed cavity is reset, and then the first electric push rod 5 drives the punch 7 to reset upward, and the punch 7 drives the push cylinder 601 to reset synchronously, and the push cylinder 601 drives the rotating shaft 701 at the bottom to move upward synchronously, and the rotating shaft 701 drives the gear 702 thereon to move upward synchronously, and the gear 702 moves upward along the tooth group at the bottom of the second rack 703, and the gear 702 drives the connecting hole 705 on the rotating shaft 701 to rotate, so that the rotating shaft 701 cuts off the connection between the closed cavity and the second connecting pipe 604, and at the same time the fifth elastic element 704 is reset, and then the push cylinder 601 drives the rotating shaft 701 at the bottom to continue to move upward, and at this time the push cylinder 601 The piston shaft 602 slides upward to reduce the volume of the closed cavity. At this time, the gas pressure in the closed cavity increases until the rotating shaft 701 drives the gear 702 thereon to contact the teeth at the top of the second rack 703. At this time, the gear 702 moves along the second rack 703, and the gear 702 drives the connecting hole 705 on the rotating shaft 701 to rotate so that the closed cavity is connected to the second connecting pipe 604. At this time, the high-pressure gas in the closed cavity impacts the clothing residues remaining in the punching knife 7 along the second connecting pipe 604 and the four ventilation channels 605 of the annular array, so that the clothing residues are separated from the punching knife 7, so as to avoid the residues left in the punching knife 7 affecting the buttonhole opening effect of the next clothing, and the cycle is repeated until the buttonhole opening of the clothing is completed.
