Description

Technical Field

[0001] This invention relates to the field of elastic band cutting technology, specifically to an elastic band tension-adjustable cutter for underwear. Background Technology

[0002] In the field of underwear manufacturing, elastic bands are a core auxiliary material. Their cutting quality directly determines the fit, comfort, and durability of underwear. It is one of the key processes affecting the quality of underwear products. With the rapid development of the underwear industry, consumers' requirements for the personalization and comfort of underwear are constantly increasing, and elastic band cutters play an important role.

[0003] Existing cutting machines typically require manual pressing of the elastic band by the operator, but this cannot be kept constant, easily resulting in overstretching or insufficient tension. During the cutting process, the elastic band is prone to lateral displacement due to tension fluctuations, causing the cut to be tilted and the length to deviate, resulting in inconsistent elastic recovery of the elastic band after cutting. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a tension-adjustable cutter for underwear elastic bands. This solves the problem that existing cutters typically require operators to manually press and fix the elastic band, which can easily cause the elastic band to shift laterally due to tension fluctuations during the cutting process, resulting in tilted cuts and length deviations.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an elastic band tension adjustable cutter for underwear, comprising a housing, a support platform fixedly connected inside the housing, a first electric push rod fixedly connected to the upper surface of the housing, a cutting blade fixedly connected to the output end of the first electric push rod, a cutting slit opened on the upper surface of the support platform, a limit sliding post fixedly connected to the lower surface of the cutting blade, a fixing component provided inside the support platform, and an outer casing fixedly connected to the outside of the housing.

[0006] Preferably, the fixing component includes a second electric push rod, the bottom of which is fixedly connected to the inside of the support platform, a lifting plate is fixedly connected to the output end of the second electric push rod, a transmission column is rotatably connected inside the lifting plate, a pressing plate is fixedly connected to the outside of the transmission column, and a support column is fixedly connected to the upper surface of the support platform.

[0007] Preferably, a motor is fixedly connected inside the housing, the output end of the motor is connected to a first wheel, a transmission belt is provided outside the first wheel, a second wheel is provided at the other end of the transmission belt, a transmission rod is fixedly connected inside the second wheel, a transmission assembly is provided at the other end of the transmission rod, an outer frame is fixedly connected to the lower surface of the transmission assembly, and a roller is rotatably connected inside the outer frame.

[0008] Preferably, the transmission assembly includes a turntable, the interior of which is fixedly connected to the other end of the transmission rod, the exterior of which is rotatably connected to a transmission plate, the other end of which is rotatably connected to a sliding plate, and the upper surface of the outer frame is fixedly connected to the lower surface of the sliding plate.

[0009] Preferably, a limiting frame is fixedly connected to the outside of the housing, and the slide plate is slidably connected to the inside of the limiting frame.

[0010] Preferably, a drive shaft is fixedly connected to the outside of the first rotating wheel, a push assembly is provided outside the drive shaft, a rotating column is fixedly connected to the outside of the drive shaft, a closing plate is slidably connected inside the push assembly, a rotating wheel is rotatably connected to the outside of the housing, and a spring is fixedly connected between the closing plate and the housing.

[0011] Preferably, the pushing assembly includes a rotating column, the rotating column is fixedly connected to the outside of the transmission shaft, a pushing column is slidably connected to the outside of the rotating column, a push plate is slidably connected to the lower side of the pushing column, a transmission frame is fixedly connected to the outside of the push plate, one end of the closing plate is slidably connected to the inside of the transmission frame, and the outside of the push plate is slidably connected to the outside of the rotating wheel.

[0012] Preferably, the drive shaft is externally rotatably connected to the inside of the outer casing.

[0013] Preferably, the support platform has an air outlet for heating inside, and a hot air blower is provided at the bottom of the casing.

[0014] Preferably, the upper surface of the closing plate is slidably connected to the bottom of the housing.

[0015] Working principle: After the motor starts, the output torque drives the first rotating wheel to rotate. The first rotating wheel transmits power to the second rotating wheel through the transmission belt. The second rotating wheel drives the transmission rod to rotate synchronously. The transmission rod drives the turntable to rotate. The turntable pulls the slide plate to slide back and forth along the inside of the limit frame through the transmission plate. The slide plate drives the outer frame and rollers to move synchronously. When the rollers roll, they apply pressure to the elastic band on the support platform to achieve positioning, pressing and wrinkle flattening.

[0016] At the same time, when the first rotating wheel rotates, it drives the transmission shaft and rotating column to rotate synchronously. The rotating column pushes the push column to move, and the push column drives the push plate to slide along the outside of the rotating wheel. The push plate pulls the closing plate through the transmission frame to overcome the elastic force of the spring and slide, so that the air outlet opens. The hot air generated by the hot air blows to the elastic band through the air outlet, realizing surface uniformity and positioning assistance.

[0017] Subsequently, the output end of the second electric push rod pushes the lifting plate upward, the lifting plate drives the transmission column to rise, and the transmission column drives the pressing plate to rotate around the support column, so that the pressing plate presses the elastic band to complete the fixation;

[0018] Finally, the output end of the first electric push rod pushes the cutting blade downwards, and the cutting blade moves vertically downwards along the guide of the limiting slide column, accurately embedding into the blade slot of the support platform to complete the cutting action of the elastic band; each component resets through reverse movement, waiting for the next cutting cycle.

[0019] This invention provides a tension-adjustable cutter for elastic bands in underwear. It offers the following advantages:

[0020] 1. In this invention, a motor drives a first rotating wheel to rotate. The first rotating wheel drives a transmission rod to rotate synchronously via a transmission belt and a second rotating wheel. The transmission rod drives a turntable to rotate. The turntable pulls a sliding plate back and forth via a transmission plate. The sliding plate drives the outer frame and rollers to move synchronously. When the rollers roll, they apply pressure to the elastic band on the support platform, thereby achieving the effect of positioning the elastic band and flattening the wrinkles of the elastic band.

[0021] 2. In this invention, the first rotating wheel drives the transmission shaft and rotating column to rotate. The rotating column pushes the push column to move, and the push column drives the push plate to slide. The push plate pulls the closing plate through the transmission frame to overcome the elastic force of the spring and slide, so that the air outlet opens. The hot air generated by the hot air blows to the elastic band through the air outlet, thereby making the overall tension of the elastic band more uniform, and thus improving the stability of the roller's positioning of the elastic band.

[0022] 3. The present invention pushes the lifting plate upward through the output end of the second electric push rod. The lifting plate drives the transmission column to rise, and the transmission column drives the pressing plate to rotate around the support column, so that the pressing plate presses the elastic band to complete the fixation. This can further fix the elastic band on the upper surface of the support platform and improve the quality of elastic band cutting. Attached Figure Description

[0038] Specifically, after the motor 9 is started, it drives the first rotating wheel 10 to rotate. The first rotating wheel 10 drives the second rotating wheel 12 to rotate through the transmission belt 11. The second rotating wheel 12 drives the transmission rod 13 to rotate synchronously. The transmission rod 13 drives the turntable 14 to rotate. The turntable 14 pulls the slide plate 16 to slide back and forth along the inside of the limiting frame 19 through the transmission plate 15. The slide plate 16 drives the outer frame 17 and the roller 18 to move synchronously. When the roller 18 rolls, it applies pressure to the elastic band to adjust the tension.

[0039] Please see the appendix Figure 7 and attached Figure 8The first rotating wheel 10 is externally fixedly connected to a drive shaft 20. A push assembly is provided externally to the drive shaft 20. A rotating column 21 is externally fixedly connected to the drive shaft 20. A closing plate 25 is slidably connected internally to the push assembly. A rotating wheel 26 is rotatably connected externally to the housing 1. A spring 27 is fixedly connected between the closing plate 25 and the housing 1. The push assembly includes a rotating column 21. The rotating column 21 is externally fixedly connected to the outside of the drive shaft 20. A push column 22 is slidably connected externally to the outside of the rotating column 21. A push plate 23 is slidably connected externally to the lower side of the push column 22. A drive frame 24 is externally fixedly connected externally to the push plate 23. One end of the closing plate 25 is slidably connected externally to the inside of the drive frame 24. The push plate 23 is slidably connected externally to the outside of the rotating wheel 26. The drive shaft 20 is rotatably connected externally to the inside of the outer casing 8. An air outlet 28 for heating is opened inside the support platform 2. A hot air blower 29 is provided at the bottom of the housing 1. The upper surface of the closing plate 25 is slidably connected to the bottom of the housing 1.

[0040] Specifically, when the first rotating wheel 10 rotates, it drives the transmission shaft 20 and the rotating column 21 to rotate synchronously. During the rotation of the rotating column 21, it pushes the push column 22 to move. The push column 22 drives the push plate 23 to slide along the outside of the rotating wheel 26. The push plate 23 is used to pull the closing plate 25 through the transmission frame 24 to overcome the elastic force of the spring 27 and realize the opening and closing of the air outlet 28. After the hot air blower 29 is started, the hot air generated is blown to the elastic band pressing area through the air outlet 28.

[0041] Workflow: In the initial state of the equipment, the pressing plate 74 is in the raised position, and the cutting blade 4 is in the initial high position. The elastic band of the underwear to be cut is placed on the upper surface of the support table 2, so that the elastic band covers the area where the cut seam 5 is located. The motor 9 is started, and the output end of the motor 9 drives the first rotating wheel 10 to rotate. The first rotating wheel 10 drives the second rotating wheel 12 to rotate synchronously through the transmission belt 11. The second rotating wheel 12 drives the transmission rod 13 to rotate, and the transmission rod 13 drives the turntable 14 to rotate. The turntable 14 pulls the slide plate 16 to slide back and forth along the inside of the limiting frame 19 through the transmission plate 15. The slide plate 16 drives the outer frame 17 and the roller 18 to move synchronously. When the roller 18 rolls, it applies pressure to the elastic band, which can achieve the positioning of the elastic band and flatten the wrinkles of the elastic band, thereby improving the quality of subsequent cutting of the elastic band.

[0042] Simultaneously, when the first rotating wheel 10 rotates, it drives the transmission shaft 20 and the rotating column 21 to rotate synchronously. During the rotation of the rotating column 21, it pushes the push column 22 to move. The push column 22 drives the push plate 23 to slide along the outside of the rotating wheel 26. The push plate 23 pulls the closing plate 25 through the transmission frame 24 to overcome the elastic force of the spring 27 and slide, so that the air outlet 28 opens and the hot air fan 29 is started. The hot air generated by the hot air fan 29 blows to the pressing area of ​​the elastic band through the air outlet 28, thereby reducing the uneven local elasticity caused by temperature differences or material characteristics. Combined with the pressing adjustment of the roller 18, the overall tension of the elastic band is more uniform, thereby improving the stability of the positioning of the elastic band by the roller 18.

[0043] The second electric push rod 71 is activated, and its output end pushes the lifting plate 72 upward. The lifting plate 72 drives the transmission column 73 to rise synchronously. The transmission column 73 drives the pressing plate 74 to rotate around the support column 75, so that the pressing plate 74 moves closer to the upper surface of the support platform 2 and presses the elastic band, thereby further fixing the elastic band on the upper surface of the support platform 2 and improving the quality of the elastic band cutting.

[0044] After the elastic band is fixed, the first electric push rod 3 is activated, and its output end pushes the cutting blade 4 downward. The cutting blade 4 moves vertically downward along the guide direction of the limiting slide 6 and is precisely embedded in the blade slot 5 on the support platform 2 to complete the cutting action of the elastic band.

[0045] After cutting, remove the cut elastic band, and the equipment returns to its initial state, completing one complete cutting cycle.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
