Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of knitting, and particularly relates to a computerized flat knitting machine for fabric processing. BACKGROUND

[0002] The flat knitting machine is a double needle plate tongue needle horizontal weft knitting machine, which functions through a cam device like a group of plane cams, and the stitches of the knitting needle can enter the groove of the cam, the cam device is moved to push the stitches of the knitting needle to make regular lifting movement in the needle groove of the cam device, and through the action of the needle hook and the needle tongue, the yarn can be knitted into a knitted fabric. During the lifting process of the knitting needle, the loop gradually exits the needle hook, the needle tongue is opened, and the needle tongue is hung on the needle bar; during the descending process of the knitting needle, the needle hook hooks the newly laid yarn and pulls it to bend into a loop, and at the same time, the original loop is detached from the needle hook, and the new loop passes through the old loop and is connected in series with the old loop, and the loops knitted by the plurality of knitting needles are connected to form a knitted fabric.

[0003] In the prior art, the tongue needle is continuously reciprocated by the rear-end cam device, and the fabric is formed by continuous looping and interlacing. In the prior art, the surface of the yarn is covered with some lint, the yarn is pulled by the yarn feeder and is hooked by the needle, and some lint will fall off when the tongue needle hooks. At the same time, the cam device repeatedly moves horizontally at a relatively high speed, and the lint is easily dropped on the needle bed or the upper end of the tongue needle due to the continuous use. The lint is easily led into the gap between the adjacent tongue needles due to the reciprocating movement and the extension and contraction of the tongue needle, and is continuously accumulated, which causes the tongue needle to be blocked or hindered in movement. When the gap is accumulated too much, the movement of the tongue needle will be deviated, and even the knitting will be missing or the needle will be stuck. In the prior art, the needle bed needs to be cleaned regularly to accumulate the lint, which reduces the work efficiency. At the same time, the cleaning is relatively inconvenient due to the small gap, and therefore, the application proposes a new solution, which can be simply cleaned and reduced to accumulate during the working process, improve the use time, and reduce the risk of blockage.

[0013] Compared with the prior art, the present application has the following advantages:

[0014] Firstly, after using the device, the yarn on the top of the equipment body is threaded through the concentrator and then into the yarn nozzle according to the actual use requirements, and then the tongue needle is prepared after the front position is prepared, and the triangular device is moved according to the program input at the controller on the equipment body and the programming control, the triangular device moves in the horizontal direction of the needle bed, the triangular device pushes the needle to move along the needle groove, the tongue needle moves forward and backward, the yarn is hooked downward to form a loop and is connected with the old loop to form a fabric, and the connecting piece on the triangular device is moved synchronously to drive the push block to move, the push block is embedded in the arc-shaped groove one and moves along the arc-shaped groove one to drive the winding piece and the rotating piece to rotate, the winding of the transmission belt is cancelled, the transmission belt is cancelled to pull and bind the plug-in piece, the plug-in piece is pushed by the spring one and embedded in the gap between the adjacent tongue needles to move, the fluff between the tongue needles is contacted, and the fluff is scraped away by the movement of the plug-in piece, thereby reducing the accumulation of the fluff and avoiding the influence of excessive accumulation on the movement of the tongue needle.

[0015] Secondly, when the transmission belt is pulled, it will move along the limiting groove, and the transmission belt will not deviate when moving under the limitation of the limiting groove, and will abut against the transmission wheel. Therefore, the movement of the transmission belt will drive the transmission wheel to rotate synchronously, and the clamped sleeve will also rotate and lift. After the transmission belt is unwound, the insert is pushed by the spring to embed into the gap between the needles, and the sleeve also rotates and lifts to drive the insert to rotate and lift. Thus, when the insert is embedded between the needles, it will rotate to pick out the lint in the needles. During the knitting process, the lint can be automatically cleaned, reducing the accumulation of lint in the gap between the needles. After the accumulation is reduced, the accumulation of too much lint can also be avoided to block the movement of the needles, thereby reducing the problems of needle jamming and blocking caused by the accumulation of too much lint.

[0016] Thirdly, after the sleeve drives the insert to rotate to abut against the air extractor at the upper end, the insert will synchronously squeeze the switch to make the switch control the air extractor to open the air extraction. At the same time, the insert is embedded into the sleeve two, and the sleeve one also abuts against the pressing piece at the top. By compressing the pressing piece downward, the protrusion is driven to move along the arc-shaped groove two in the rotating wheel, the rotating wheel is controlled to rotate, and the meshing bevel gear is synchronously driven to rotate. Thus, the bevel gear drives the winding rod to rotate, cancels the winding of the pull rope on the expansion plate, and makes the expansion plate be pushed by the spring two to expand and cover the insert, avoiding the falling of the upward picked out lint.

[0017] Fourthly, the triangular device will move horizontally and reciprocally, so that when it is reset, the push block will move along the winding member and the rotating member, and will move along the arc-shaped groove one on the rotating member at the same time, so as to push the winding member and the rotating member to reset, and drive the winding member to rewind the transmission belt. Thus, the insert is moved backward and embedded into the sleeve one, and the spring one is compressed. Secondly, the insert moves along the expansion plate and the sleeve two, so that the lint is sucked away by the air inlet when the insert moves. When the insert is re-embedded into the sleeve one and is no longer blocked by the expansion plate, the transmission belt is also reset, and the teeth on the transmission belt are also separated from the transmission wheel. At this time, the spring will push the sleeve one and the transmission wheel to reset, and rotate downward again. Thus, it is arranged to ensure that the sleeve one does not rotate when the insert moves outward, and the sleeve one is reset after the insert is reset, so as to ensure that the lint on the insert is sucked away and will not be in the state of stretching outward during the reset, avoiding the falling of the lint on the needle bed again.

Needle bed 2 is provided with blocking piece 6 for blocking the latch needle, blocking piece 6 is provided with a plurality of inserts 7 embedded between adjacent latch needles, sleeve one 8 is rotatably connected in blocking piece 6, and sleeve one 8 is slidably connected with insert 7, triangular device 5 is provided with connecting piece 9 embedded in blocking piece 6, blocking piece 6 is provided with sliding groove 10 for guiding the movement of connecting piece 9, driving assembly for driving insert 7 to move and retract along sleeve one 8 is rotatably connected in blocking piece 6, driving assembly includes push block 11 arranged on connecting piece 9, a plurality of winding pieces 12 are rotatably connected in blocking piece 6, a plurality of winding pieces 12 are rotatably connected with rotating piece 13, arc slot one 14 is arranged on rotating piece 13 for accommodating push block 11, and push block 11 moves along arc slot one 14 to drive rotating piece 13 to rotate, transmission belt 15 is wound on winding piece 12, and the other end of transmission belt 15 is connected with insert 7, and after using the device, the movement of triangular device 5 will drive connecting piece 9 to move synchronously, so that connecting piece 9 drives push block 11 to move synchronously, because push block 11 and connecting piece 9 are arranged at the edge of triangular device 5 close to the device body 1, so that the triangular device 5 will first withdraw the latch needle to hook the yarn into a loop, and then reset to wait for push block 11 and connecting piece 9 to move along sliding groove 10 to the component after the needle end, then move along arc slot one 14 on rotating piece 13 embedded in rotating piece 13 rotatably connected with blocking piece 6, push rotating piece 13 through arc slot one 14 to rotate, because rotating piece 13 and winding piece 12 are rotatably connected synchronously, so that winding piece 12 rotates and cancels the winding of transmission belt 15, at the same time, because winding piece 12 is smaller than rotating piece 13, so that push block 11 will not contact with winding piece 12, to avoid the limitation of being stuck, secondly, when winding piece 12 cancels the winding of transmission belt 15,The spring 19 in the kit 8 is released to push the plug-in 7 outwardly first, embedded in the gap between the adjacent needles, and then the soft rubber head 21 at one end of the plug-in 7 is abutted on the needle bed 2, which can reduce the impact and damage of the plug-in 7 on the needle bed 2. After the plug-in 7 is abutted on the needle bed 2, the transmission belt 15 with teeth is abutted with the teeth of the half gear of the transmission wheel 18. At this time, the plug-in 7 is continuously pushed by the spring 19, and through the pushing force and the smoothness generated by the lubrication on the needle bed 2, the plug-in 7 will be slightly rotated between each other, and then the transmission belt 15 will drive the transmission wheel 18 to rotate, thereby controlling the rotation of the kit 8 to lift up, so as to ensure that when the plug-in 7 extends along the gap, the kit 8 will drive the plug-in 7 to rotate, and the lint contacted by the plug-in 7 will be lifted and taken out by the cleaning strip 22. The plug-in 7 is like a brush embedded in the gap to move and rotate upward to take out the lint, reduce the accumulation of lint in the gap, thereby ensuring that the lint can be cleaned when the device is started, and the cleaning is also driven by the triangular device 5 after the needle is driven, avoiding the influence and hindering of the needle, and reducing the accumulation of lint after a long time of use, thereby reducing the number of needle jamming caused by the accumulation of lint.

[0032] The blocking piece 6 is provided with a limiting groove 16 for guiding and limiting the deviation of the transmission belt 15. The blocking piece 6 is rotatably connected with the kit 8 through the rotating rod 17. The rotating rod 17 is clamped in the kit 8 and provided with the transmission wheel 18 engaged with the transmission belt 15. The transmission wheel 18 is located on the moving path of the transmission belt 15 and opposite to the limiting groove 16. The kit 8 is provided with the spring 19 for pushing the plug-in 7 to move. The spring 19 has a greater elastic force than the self-weight of the plug-in 7 and the kit 8, and a smaller elastic force than the pulling force of the winding piece 12 rotating to wind. The kit 8 is provided with the guide groove 20 for guiding and limiting the plug-in 7. The plug-in 7 is provided with the rubber head 21 at the abutting part with the needle bed 2. The surface of the plug-in 7 is distributed with the soft cleaning strip 22 for taking away the lint. When the winding piece 12 stops winding the transmission belt 15, the transmission belt 15 moves along the limiting groove 16 at the lower end of the transmission wheel 18 and does not appear to be out of position. Thus, when the teeth on the transmission belt 15 near the winding piece 12 move to the transmission wheel 18, the teeth can abut with the teeth of the half gear, and the transmission wheel 18 is driven to rotate, so that the transmission wheel 18 drives the kit 8 to rotate and lift up, ensuring that the plug-in 7 can first be embedded in the gap and then rotate. The elastic force of the spring 19 is greater than the self-weight, so that the spring 19 drives the transmission belt 15 to move and drive the kit 8 to rotate, avoiding the situation that the kit 8 is stuck or cannot rotate upward. The plug-in 7 moves along the center line of the kit 8 through the guide groove 20, avoiding the deviation, and ensuring that the plug-in 7 can be embedded between the adjacent needles.

[0033] The upper end of the blocking piece 6 is provided with an air extraction piece 23, the side of the needle bed 2 is provided with a hose connected with the air extraction piece 23, the air extraction piece 23 is provided with a switch 24 for controlling the opening of the air extraction piece 23 at the position abutting against the upward rotation of the sleeve piece one 8, the air extraction piece 23 is provided with a sleeve piece two 25 accommodating the insertion of the plug 7 at the front end of the switch 24, the sleeve piece two 25 is provided with a plurality of scraping pieces 26 abutting against the plug 7 near the blocking piece 6, and the sleeve piece two 25 is provided with an expansion assembly wrapping the plug 7 to prevent excessive cotton from falling. The expansion assembly comprises two arc-shaped expansion plates 27 sliding with the sleeve piece two 25, the expansion plates 27 are provided with air suction ports 28 communicating with the sleeve piece two 25, a winding rod 29 is rotationally connected to the middle of the upper end of the sleeve piece two 25, a pull rope 30 is wound on the winding rod 29, the other end of the pull rope 30 is connected with the expansion plates 27 on both sides, and the blocking piece 6 is provided with a pressing piece 31 abutting against the sleeve piece one 8 and controlling the rotation of the winding rod 29 at the position of the switch 24. The pressing piece 31 is provided with a protrusion 32, a rotating wheel 33 is rotationally connected in the air extraction piece 23, and the rotating wheel 33 is sleeved on the outside of the pressing piece 31, the rotating wheel 33 is provided with an arc-shaped groove two 34 accommodating the embedding of the protrusion 32 and driving the rotation of the rotating wheel 33, and a bevel gear 35 is provided on the winding wheel and engaged with the rotating wheel 33. The sleeve piece two 25 is provided with a spring two 36 driving the movement of the expansion plates 27, and the expansion plates 27 are provided with rollers 37 rolling with the sleeve piece two 25. When the sleeve piece one 8 is rotated upward and abuts against the switch 24 and then abuts against the pressing piece 31 on the air extraction piece 23, the switch 24 controls the opening of the fan and other control components connected with the air extraction piece 23, the air extraction piece 23 is opened to extract air, and the sleeve piece two 25 is communicated with the air extraction piece 23, so that the air suction ports 28 of the sleeve piece two 25 have suction force, the plug 7 and the surface cleaning strip 22 are attached to the sleeve piece two 25, the pressing piece 31 is pressed, the protrusion 32 is moved to drive the rotating wheel 33 along the arc-shaped groove two 34 of the rotating wheel 33, the rotating wheel 33 is rotated to drive the synchronous rotation of the engaged bevel gear 35, the winding rod 29 in the sleeve piece two 25 is rotated, and the winding of the pull rope 30 is cancelled, so that the expansion plates 27 are unfolded to wrap the plug 7 under the self-weight and the driving of the spring two 36, the movement of the expansion plates 27 is smoother under the action of the rollers 37, and the suction force of the air suction ports 28 on the cleaning strip 22 and the plug 7 can suck away the lint adhered to the cleaning strip 22 and the plug 7.

[0034] The transmission wheel 18 is a half gear, and the transmission belt 15 has teeth near one end of the winding member 12, which are engaged with the transmission wheel 18. A push sleeve 8 is arranged between the transmission wheel 18 and the blocking member 6, and a spring 41 is arranged to reset the transmission wheel 18. The diameter of the winding member 12 is smaller than that of the rotating member 13, and a plurality of rotating members 13 are arranged adjacently. The tail of the arc-shaped slot 14 on the adjacent rotating member 13 is opposite to the head of the arc-shaped slot 14 on the adjacent rotating member 13 after rotation. When the connecting member 9 and the push block 11 move, they move along the arc-shaped slot 14 of the rotating member 13, are embedded at the head of the arc-shaped slot 14, move transversely and push the rotating member 13 to rotate, slide out at the tail of the arc-shaped slot 14, and are opposite to the head of the arc-shaped slot 14 of the adjacent rotating member 13 after rotation. In this way, it is ensured that after the push block 11 is separated from the previous rotating member 13, it is embedded at the head of the arc-shaped slot 14 of the next rotating member 13, and it is ensured that after resetting, it moves along the tail of the arc-shaped slot 14 of the pushed rotating member 13, moves along the arc-shaped slot 14 to the head of the arc-shaped slot 14, and then enters the tail of the arc-shaped slot 14 of the adjacent rotating member 13 again. In this way, it is ensured that the reciprocating movement will not be blocked or stuck. Thus, the resetting of the push block 11 pushes the rotating member 13 to rotate, and the winding member 12 is rewound to the transmission belt 15. When the transmission belt 15 is wound, the part with teeth of the transmission belt 15 is first moved. When the transmission belt 15 is reset by the spring 19, the teeth of the transmission belt 15 are separated from the half gear teeth of the transmission wheel 18, and will not continue to abut each other. In this way, the resetting will not drive the half gear to reset and compress the spring 41. Thus, the transmission belt 15 is wound, the insert 7 is first moved backward, the cleaning strip 22 is moved backward and abuts against the scraping piece 26, the soft part is bent along the scraping piece 26, and the lint that is not sucked away is hung and falls downward to be sucked away by the suction port 28. Then, the insert 7 is completely embedded in the sleeve 8, is separated from the blocking of the expansion plate 27, and the transmission belt 15 pulls the spring 19 to reset the insert 7. The spring 41 can push the sleeve 8 to move downward again. The elastic force of the spring 41 can overcome the stress of the compressed spring 19 and the insert 7, so that the spring 41 pushes the transmission wheel 18 to reset to a position where the transmission wheel 18 abuts against the teeth of the transmission belt 15. In this way, it is ensured that when the transmission belt 15 moves again, the transmission wheel 18 can still be pushed to rotate and continue to be used.When resetting, the protrusion 32 on the pressing piece 31 is synchronously moved upward to push the rotating wheel 33 along the arc-shaped slot two 34 of the rotating wheel 33, so that the rotating wheel 33 drives the bevel gear 35 to rotate and reset the winding wheel to re-wind the pull rope 30, so that the expansion plate 27 is re-embedded into the kit two 25, ensuring the next use, while the air extraction piece 23 can slide with the blocking piece 6, and a corrugated pipe can be added at the rear end of the air extraction piece 23 to ensure that the air extraction piece 23 can be pulled out for use, which can be designed and added according to actual application.

[0035] The winding piece 12 and the rotating piece 13 are rotatably connected with a pull rod 38, the pull rod 38 is slidably connected with the blocking piece 6, the pull rod 38 is provided with a clamping piece 39, the winding piece 12 is provided with a clamping groove 40 for accommodating the clamping piece 39, and one end of the pull rod 38 penetrates out of the blocking piece 6. After shutdown, the pull rod 38 at the side of the blocking piece 6 can be pulled to the side, so that the plurality of clamping pieces 39 on the pull rod 38 are moved from the annular groove in the rotating piece 13 to the clamping groove 40 of the winding piece 12. Under normal conditions, the clamping piece 39 is located in the annular groove of the rotating piece 13, so as not to rotate synchronously. After moving and being embedded into the clamping groove 40 of the winding piece 12, the pull rod 38 is ensured to rotate synchronously with the winding piece 12. The winding piece 12 and the rotating piece 13 are connected by the equal setting of each winding piece 12 and the plurality of clamping pieces 39. Thus, the winding piece 12 can be driven to rotate by the rotation of the pull rod 38 to drive the internal plug-in piece 7, so as to achieve synchronous cleaning. After shutdown, the tongue needle can be cleaned by one key to reduce the accumulation of lint. Thus, direct switching is more convenient, and the connecting piece 9 can also be detached from the triangular device 5 through bolts, so that the connecting piece 9 can be detached during automatic cleaning without long-time work.
