Description

Technical Field

[0001] This invention relates to the field of sleeve fitting machines, and particularly to a sleeve fitting machine. Background Technology

[0002] A sew-on machine, also known as a circular sewing machine, is a machine that uses sewing thread to sew the opening of a sweater. With the help of a sewing machine, sweater knitting can be completed efficiently and quickly, greatly improving work efficiency.

[0003] After prolonged use, the needles on the needle plate of the sealing machine may break. Currently, needles are usually replaced manually. During the replacement process, nearby needles need to be removed and disassembled as well. Manual replacement can lead to some deviation, resulting in the outer diameter of the needle being inconsistent with the surrounding area. Manual hammering for tightening can cause wear and misalignment of the reinstalled needles. In addition, needles mixed with other needles after use and replacement contain some impurities, which need to be cleaned before reuse. To address these issues, a solution is proposed below. Summary of the Invention

[0004] The purpose of this invention is to provide a fitting machine that allows for easy replacement of needles using mating parts and clamping parts, effectively solving the problems of needle misalignment, errors, or wear during tightening when replacing needles manually in the traditional way. The cleaning mechanism can effectively clean the entire needle plate.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A needle-jointing machine includes a needle disc, a needle-pressing cover, a support base, and a cleaning mechanism. The needle disc is mounted on the support base. The needle-pressing cover is installed in a groove on the needle disc. A mounting mechanism for connecting needles is installed between the needle disc and the needle-pressing cover. The mounting mechanism includes a clamping member and a mating member. The mating member is installed in the groove for clamping the needles. The clamping member is installed on the mating member for reinforcing the tightness of the needles on the mating member. The cleaning mechanism is installed on the support base for cleaning impurities on the surface of the needles.

[0007] Using the above technical solution, the grooves on the needle plate are ring-shaped and have distinct steps. The needle pressure cover is positioned on the uppermost step. The new needle is fitted onto the mating part, and the clamping part further secures the needle, ensuring its stability after installation. Several mating parts are placed in the groove, each forming a complete circle. For replacement, simply open the needle pressure cover to remove the mating part and replace the needle. After replacement, the needle is placed back into the groove and fixed in position by bolts threaded through the needle pressure cover and the needle plate. After installation or long-term use, the needles will accumulate impurities and residual oil. A cleaning mechanism will then remove these impurities and maintain cleanliness.

[0008] Preferably, the mating parts are arranged in a circumferential arrangement within the groove. The mating parts include an upper clamping block and a lower clamping block, with one end of the upper and lower clamping blocks hinged together. The end faces of the upper and lower clamping blocks that are close to each other are provided with slots for clamping the needles.

[0009] Using the above technical solution, the slots on the upper and lower clamping blocks fit together to form a complete circle, which can match the diameter of the needle punch. The slots on the upper and lower clamping blocks are semi-circular, and each upper and lower clamping block has 2 to 5 slots.

[0010] Preferably, the clamping element includes an elastic plate, a retaining shell, a spring, and a flip plate. The retaining shell is mounted on the lower clamping block. One end of the spring is connected to the inner wall of the retaining shell, and the other end of the spring is connected to the flip plate. The end of the flip plate away from the spring is rotatably engaged with the retaining shell. One end of the elastic plate is rotatably engaged with the lower clamping block, and the other end of the elastic plate is abutted against the flip plate inside the retaining shell.

[0011] Using the above technical solution, after the needle is replaced, it is placed in the slot of the lower clamping block. The elastic sheet is flipped over, and the end of the elastic sheet that does not rotate with the lower clamping block is inserted into the clamping case. The spring will drive the flipping plate in the clamping case to press against the elastic sheet. The elastic sheet can effectively secure the needle and prevent the needle from shifting after installation. A small space is reserved on the upper clamping block for the elastic sheet to be accommodated.

[0012] Preferably, the cleaning mechanism includes a cover, a transmission component, and a cleaning component; the cover is symmetrically arranged on both sides of the needle plate; the transmission component is mounted on a support base and is used to drive the cleaning component; the cleaning component is installed inside the cover and is used to clean impurities on the needle.

[0013] Using the above technical solution, after the transmission component is started, it drives the cleaning component inside the housing to perform a cleaning operation on the needle plate.

[0014] Preferably, the transmission component includes a servo motor, a gear, a gear ring, a turntable, a connecting rod, and a connecting column. The servo motor is mounted on one side of the support base, the gear is mounted on the output shaft of the servo motor, the gear ring is mounted on the support base, and the gear ring and the gear mesh with each other. The connecting rod is mounted on the gear ring, and the connecting column connects the covers located above and below the needle plate. The turntable is installed inside the cover and rotates in cooperation with the cleaning component.

[0015] Using the above technical solution, after the servo motor is driven, the output shaft of the servo motor drives the gear to rotate, and the gear drives the meshing gear ring to transmit power. The gear ring and the support base rotate together, and the connecting rod fixed on the gear ring can rotate around the axis of the support base. The connecting column is used to connect the upper and lower covers. The cleaning part can cover and clean the upper and lower parts of the needle, and realize circumferential ring cleaning.

[0016] Preferably, the cleaning component includes a control motor, a cleaning roller, a wiping roller, a treatment roller, and a water supply system. The output shaft of the control motor passes through the cover and connects to the turntable. The cleaning roller, wiping roller, and treatment roller are all mounted on the turntable. The control motor drives the cleaning roller, wiping roller, and treatment roller through a pulley drive. The water supply system is installed on one side of the support base.

[0017] Using the above technical solution, after the control motor starts, it drives the turntable to rotate. The cleaning roller, wiping roller, and treatment roller, which are arranged in a triangular fixed pattern on the turntable, rotate together with the turntable. The wiping roller wipes away moisture and dirt from the needled surface, the cleaning roller cleans the impurities wrapped around the needled surface, and the treatment roller polishes the replaced or burr-containing parts. The cleaning roller, wiping roller, and treatment roller alternately contact and clean the needled surface as the turntable rotates. The water supply system provides a certain amount of water during the cleaning operation to facilitate cleaning and improve cleanliness.

[0018] Preferably, the water supply system includes an atomizing pipe, a water pump, a water storage tank, and a solenoid valve. The atomizing pipe is installed inside the housing, the water storage tank is installed on one side of the support base, the water pump is installed on one side of the water storage tank, the water pump and the water storage tank are connected by a pipe, the water pump and the atomizing pipe are connected by a pipe, and the solenoid valve is installed on the pipe connecting the water pump and the atomizing pipe.

[0019] Using the above technical solution, the water pump and solenoid valve are turned on, and the water in the water storage tank is transported along the pipeline to the atomizing tube. The atomizing tube sprays water onto the needle-pierced area for easy cleaning.

[0020] Preferably, the support base is also equipped with a lifting device, which includes a bevel gear set, a mounting base, a screw, a screw sleeve, and a wheel. The screw is installed in a groove in the support base, the bevel gear set is installed on the screw and the wheel, the screw sleeve is installed on the screw and is connected to the mounting base through a gap, the servo motor is installed on the mounting base, and the wheel is installed on the bevel gear set.

[0021] Using the above technical solution, the wheel is manually rotated, which drives one of the bevel gears to rotate. The other bevel gear meshing with it drives the screw to rotate in the support seat. The rotation of the screw drives the screw sleeve and the mounting seat to move vertically, realizing the lifting and lowering motion, thereby lifting and lowering the gear ring and the connecting rod.

[0022] Preferably, the connecting rod is also equipped with an adjusting component, which includes a slider, a lead screw, and a rotating wheel. A groove is provided on the end face of the connecting rod facing the cover. The lead screw passes through the slider and rotates in the groove. The lead screw and the slider are threadedly engaged, and the slider and the groove are slidably engaged. The rotating wheel is installed at the end of the lead screw that extends out of the connecting rod.

[0023] Using the above technical solution, the rotating wheel is manually adjusted, which drives the lead screw to move within the slide groove. The lead screw then drives the slider within the slide groove to slide. The slider and the cover are fixedly fitted together, and the cover can move along the axis of the lead screw, thereby achieving the adjustment of the horizontal position of the cover.

[0024] Beneficial effects: 1. After replacing broken or damaged needles with mating parts and clamping parts, it can prevent installation deviation and wear problems during manual installation;

[0025] The needle is held by the upper and lower clamping blocks and further secured by the clamping parts, which simplifies the traditional installation process and reduces the labor output for manual workers.

[0026] The cleaning structure alternately cleans the surface of the needled area, effectively cleaning the needled surface. Attached Figure Description

[0040] The groove 5 on the needle plate 1 is ring-shaped and has distinct steps. The needle pressure cover 2 is positioned on the uppermost step. The new needle is fitted onto the mating part 62, and the needle is further secured by the clamping part 61 to ensure the stability of the installation. The mating part 62 is placed in the groove 5. There are several mating parts 62, each forming a complete circle in the groove 5. When replacing, simply open the needle pressure cover 2 to remove the mating part 62 and replace the needle. After replacement, the needle is placed back into the groove 5. The position is fixed by bolts passing through the threaded engagement between the needle pressure cover 2 and the needle plate 1. The ring-shaped needle can rotate on the turntable 424. After installation or after a period of long-term use, some impurities and residual oil will accumulate on the needle. The cleaning mechanism 4 will clean the surface of the needle to remove impurities and maintain its cleanliness.

[0041] See Figures 1 to 7As shown, the mating component 62 is arranged in a circumferential pattern within the groove 5. The mating component 62 includes an upper clamping block 621 and a lower clamping block 622. One end of the upper clamping block 621 and the lower clamping block 622 are hinged together. Each of the adjacent end faces of the upper clamping block 621 and the lower clamping block 622 has a slot for clamping the needle. The slots on the upper clamping block 621 and the lower clamping block 622 fit together to form a complete circle, which perfectly matches the diameter of the needle. The slots on the upper clamping block 621 and the lower clamping block 622 are semi-circular, and each upper clamping block 621 and lower clamping block 622 has 2 to 5 slots.

[0043] After the needle is replaced, it is placed in the slot of the lower clamping block 622. The elastic plate 611 is flipped over, and the end of the elastic plate 611 that does not rotate with the lower clamping block 622 is inserted into the retaining case 612. The spring 613 will drive the flipping plate 614 in the retaining case 612 to press against the elastic plate 611. The elastic plate 611 can secure the needle well and prevent the needle from shifting after installation. A small space is reserved on the upper clamping block 621 to accommodate the elastic plate 611.

[0044] See Figures 1 to 7 As shown, the cleaning mechanism 4 includes a housing 41, a transmission component 42, and a cleaning component 43. The housing 41 is symmetrically arranged on both sides of the needle plate 1. The transmission component 42 is mounted on the support base 3 and is used to drive the cleaning component 43. The cleaning component 43 is installed inside the housing 41 and is used to clean impurities on the needles. After the transmission component 42 is activated, it drives the cleaning component 43 inside the housing 41 to perform a cleaning operation on the needles on the needle plate 1.

[0045] See Figures 1 to 7 As shown, the transmission component 42 includes a servo motor 421, a gear 423, a gear ring 422, a turntable 424, a connecting rod 425, and a connecting column 426. The servo motor 421 is mounted on one side of the support base 3. The gear 423 is mounted on the output shaft of the servo motor 421. The gear ring 422 is mounted on the support base 3, and the gear ring 422 and the gear 423 mesh with each other. The connecting rod 425 is mounted on the gear ring 422. The connecting column 426 connects the cover 41 located above and below the needle plate 1. The turntable 424 is installed inside the cover 41 and rotates in cooperation with the cleaning component 43.

[0046] After being driven by the servo motor 421, the output shaft of the servo motor 421 drives the gear 423 to rotate. The gear 423 drives the meshing gear ring 422 to perform transmission. The gear ring 422 and the support base 3 rotate together. The connecting rod 425 fixed on the gear ring 422 can rotate around the axis of the support base 3. The connecting column 426 is used to connect the upper and lower covers 41. The cleaning component 43 can cover and clean the upper and lower parts of the needle and achieve circumferential cleaning.

[0047] See Figures 1 to 7 As shown, the cleaning component 43 includes a control motor 431, a cleaning roller 432, a wiping roller 433, a treatment roller 434, and a water supply system 435. The output shaft of the control motor 431 passes through the cover 41 and connects to the turntable 424. The cleaning roller 432, the wiping roller 433, and the treatment roller 434 are all mounted on the turntable 424. The control motor 431 drives the cleaning roller 432, the wiping roller 433, and the treatment roller 434 through a pulley drive. The water supply system 435 is mounted on one side of the support base 3.

[0048] After the control motor 431 is started, it drives the turntable 424 to rotate. The cleaning roller 432, wiping roller 433 and treatment roller 434, which are arranged in a triangular fixed position on the turntable 424, rotate together with the turntable 424. The wiping roller 433 wipes the needled surface with water and dirt, the cleaning roller 432 cleans the impurities wrapped around the needled surface, and the treatment roller 434 polishes the replaced or burr-containing parts. The cleaning roller 432, wiping roller 433 and treatment roller 434 alternately contact and clean the needled surface as the turntable 424 rotates. The water supply system 435 provides a certain amount of water during the cleaning operation to facilitate cleaning and improve cleanliness.

[0049] See Figures 1 to 7 As shown, the water supply system 435 includes an atomizing pipe 4351, a water pump 4352, a water storage tank 4353, and a solenoid valve 4354. The atomizing pipe 4351 is installed inside the housing 41, the water storage tank 4353 is installed on one side of the support base 3, and the water pump 4352 is installed on one side of the water storage tank 4353. The water pump 4352 and the water storage tank 4353 are connected by a pipe, and the water pump 4352 and the atomizing pipe 4351 are also connected by a pipe. The solenoid valve 4354 is installed on the pipe connecting the water pump 4352 and the atomizing pipe 4351. When the water pump 4352 and the solenoid valve 4354 are turned on, water in the water storage tank 4353 is transported along the pipe to the atomizing pipe 4351. The atomizing pipe 4351 sprays water onto the needle-punched area for easy cleaning.

[0050] See Figures 1 to 7As shown, a lifting device 31 is also installed on the support base 3. The lifting device 31 includes a bevel gear set 311, a mounting base 312, a screw 313, a screw sleeve 314, and a wheel 315. The screw 313 is installed in a groove in the support base 3. The bevel gear set 311 is installed on the screw 313 and the wheel 315. The screw sleeve 314 is installed on the screw 313 and connected to the mounting base 312 through a gap. The servo motor 421 is installed on the mounting base 312, and the wheel 315 is installed on the bevel gear set 311. Manually rotating the wheel 315 drives one of the bevel gears 423 to rotate. The other bevel gear 423 meshing with it drives the screw 313 to rotate within the support base 3. The rotation of the screw 313 drives the screw sleeve 314 and the mounting base 312 to move vertically, realizing the lifting motion, thereby lifting the gear ring 422 and the connecting rod 425.

[0051] See Figures 1 to 7 As shown, an adjusting component 4251 is also installed on the connecting rod 425. The adjusting component includes a slider 42511, a lead screw 42512, and a rotating wheel 42513. A groove is formed on the end face of the connecting rod 425 facing the cover 41. The lead screw 42512 passes through the slider 42511 and rotates in the groove. The lead screw 42512 and the slider 42511 are threadedly engaged, and the slider 42511 and the groove are slidably engaged. The rotating wheel 42513 is installed at the end of the lead screw 42512 that extends out of the connecting rod 425. The rotating wheel 42513 is manually adjusted, which drives the lead screw 42512 to move within the groove. The lead screw 42512 drives the slider 42511 within the groove to slide. The slider 42511 and the cover 41 are fixedly engaged, and the cover 41 can move along the axis of the lead screw 42512, thereby achieving horizontal position adjustment of the cover 41.

[0052] When the cleaning mechanism 4 cleans the needle-punched surface, it first manually rotates the rotating wheel 42513. The rotating wheel 42513 drives the lead screw 42512, the slider 42511, and the cover 41 on the slider 42511 to move towards the outer diameter of the needle. Next, it manually adjusts the wheel 315. The wheel 315 drives the screw 313 through the bevel gear set 311. The screw 313 drives the screw sleeve 314 and the mounting base 312 to move up and down vertically, adjusting the distance between the two covers 41 and the needle position. The needle is placed horizontally, and then the rotating wheel 42513 is manually adjusted in the opposite direction. The lead screw 42512 drives the slider 42511 and the cover 41 to move in the direction of the needle's inner diameter. When the two covers 41 are in the upper and lower positions of the needle that can be cleaned, they stop. Finally, the servo motor 421 is started. The servo motor 421 drives the gear 423, the gear ring 422 and the cover 41 on the connecting rod 425 to move in a circular motion around the axis of the support base 3, thereby cleaning the needles on the entire needle plate 1.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
