Description

Technical Field

[0001] This invention patent relates to a flat knitting machine needle plate with controllable position of the needle assembly, tooth plate, and sinker plate. Background Technology

[0002] With the continuous development of textile technology, flat knitting machines are being used more and more widely in the textile industry. Flat knitting machines are equipped with a needle plate, on which parallel insert slots are milled. Inserts are installed in the insert slots, and toothed plates, sinkers, inserts and other structural components are installed at the front end of the insert slots. Each pair of adjacent inserts forms a needle groove, and knitting needles are placed in the needle groove.

[0003] In existing models, the toothed plates installed at the doffing point of computerized flat knitting machines are all made of a single piece. The spacing between them is calculated based on the number of needles and the thickness of the toothed plate, and the distance is constant. At the same time, the design of the needle expansion spring height, needle hook size, and loop connecting rod thickness also takes the toothed plate spacing as the main reference. According to its knitting principle (one stitch per stitch), a double-needle bed computerized flat knitting machine is needed to produce 12- or 14-gauge sweaters with a large production volume. This would require a 24-gauge or 28-gauge double-needle bed computerized flat knitting machine with needle groove spacings of 1.058 mm and 0.907 mm, respectively. The thickness of the inserts and needle bars used for the combined needle grooves barely meets the requirements. However, the height of the expansion spring used for the transfer loop cannot be reduced further, and it still rubs against the toothed plate with the limit thickness. Only a reduced knitting speed can meet the requirements, but the fabric yield is still not comparable to that of a computerized machine that knits a single piece of fabric. Therefore, the demand for a double-needle bed computerized flat knitting machine with fine needle spacing, which eliminates a lot of manual labor in the later stages, is extremely high and cannot be ignored.

[0004] The applicant's existing application number 202222770899.8 has made creative improvements to the structural parts involved above, but the actual fine needle pitch and the designed needle body thickness still require further innovation on the basis of the original structure, so as to improve the knitting flat knitting machine to a new level, which is the motivation of the inventor. Summary of the Invention

[0005] The purpose of this invention is to solve the existing technical problems by proposing a flat knitting machine needle plate with controllable position of the needle assembly, tooth plate, and sinker plate.

[0006] A flat knitting machine needle plate with controllable positioning of needle assembly, toothed plate, and sinker includes a needle plate, a small needle plate, a drive device, and a sinker. The needle plate has a slot for inserting a piece, and an insert is placed in the slot. The lower rear side of the small needle plate is positioned above the front end of the insert. The upper end of the sinker has a protruding heel, which is installed in a mounting groove on the small needle plate for moving the heel of the sinker. The lower end of the sinker is a pressure nozzle. The drive device is located on the side of the needle plate. The drive device drives the small needle plate to move, causing the sinker to move left and right, effectively expanding the space between the sinker and the needle head.

The lever arm passes through the rotating hole via the rotating shaft and is rotatably connected to a bearing located in the hole of the needle plate. A cylindrical protrusion on the needle plate is fitted into the first elongated hole, and the cylindrical protrusion moves within the first elongated hole. Both ends of the lever arm are arc-shaped, and teeth are provided on both arc-shaped ends. One end of the lever arm meshes with the gear, and the other end meshes with the teeth on the rear side of the mounting block. The lower end of the mounting block is located within the first limiting cutout of the needle plate, and the mounting block moves within the first limiting cutout. The upper end of the mounting block is connected to the lower side of the small needle plate, and the lower end of the mounting block is connected to one side of the toothed plate mounting plate. The drive motor drives the lever arm, the lever arm drives the mounting block, and the mounting block simultaneously drives the small needle plate and the toothed plate mounting plate. The small needle plate is linked to the sinker plate, and the toothed plate mounting plate is linked to the toothed plate.

[0010] Furthermore, the insert includes a first insert and a second insert. The insert slot contains the first and second inserts arranged sequentially at intervals. Two adjacent first and second inserts form a needle groove. Two needles of the mirrored needle assembly are correspondingly positioned in adjacent needle grooves. Two needle pads are respectively positioned in needle grooves located above the mirrored needle assembly. The upper front end of both the first and second inserts has a U-shaped groove. The lower part of the U-shaped groove is fitted with a first needle ruler, and the upper part is fitted with a second needle ruler. A spacer is inserted into the upper edge of the U-shaped groove wall. A small needle plate is placed in the first insert. On the spacer on the upper side of the front end of the first and second inserts, and connected to the second needle ruler by screws passing through the spacer, the small needle plate is provided with an installation groove for the heel of the sinking plate to move. The lower end of the sinking plate is set in the toothed plate groove, the upper end of the sinking plate is provided with a protruding heel, the middle of the sinking plate is provided with two arc-shaped waist-shaped holes, the lower end of the sinking plate is a wire pressing nozzle, and two steel wires pass through the corresponding waist-shaped holes and are set on the upper side of the front end of the first and second inserts; the front end of the first insert groove corresponding to the first insert is provided with a gasket, one side of the gasket is provided with a stepped surface, and the stepped surfaces of adjacent gaskets face away from each other.

[0012] Furthermore, the upper protrusion on the front end of the second insert is provided with a U-shaped groove, the bottom of the U-shaped groove is provided with a protrusion, the front end of the second insert is provided with a clearance cutout on one side of the knitting needle, and the upper protrusion is provided with a first wire hole at the rear side of the U-shaped groove.

[0013] Furthermore, the needle pad is provided with a front hook body, a rear hook body, a groove, and a rear extension. The rear side of the needle pad is provided with a rear extension that matches the front end of the needle selection component. The upper end of the needle pad is also provided with a groove, and the rear side of the groove is provided with a front hook body. The groove is fitted with a first needle ruler, which controls the upper and lower gap of the needle pad. The upper rear side of the needle pad is provided with a front hook body with the hook groove facing the groove. The front hook body cooperates with the first wire hole at the upper end of the first insert and the second insert to form an installation hole for adjusting the tension of the wire. The up and down movement of the needle is adjusted by changing the outer diameter of the wire. The upper end of the front hook body is provided with a rear hook body with the hook groove facing away from the groove. The rear hook body is used for installing and removing the needle pad.

[0014] Furthermore, the rear end of the knitting needle engages with the front end of the needle selection assembly. The long needle of the needle selection assembly is provided with a downward-protruding limiting part. The damping steel wire prevents the risk of needle slippage. The damping steel wire set in the first insert and the second insert damps and limits the limiting part.

[0015] Furthermore, the driving device includes a drive motor, a pressure plate, an eccentric wheel, and a lever arm with an eccentric wheel track. The pressure plate is fixed to the rear side of the needle plate, and a fixing groove is formed between the lower front side of the pressure plate and the upper side of the needle plate. The drive motor is located at the lower side of the needle plate, and the drive shaft of the drive motor passes through the needle plate. An eccentric wheel is provided at the upper end of the drive shaft. One end of the lever arm with the eccentric wheel track extends into the fixing groove, and the eccentric wheel track is fitted with the eccentric wheel. The lever arm with the eccentric wheel track has a rotating hole, and the lever arm with the eccentric wheel track passes through the rotating hole via a rotating shaft, which is aligned with the shaft of the needle plate hole. The bearing is rotating and connected. The other end of the eccentric wheel track arm is a circular structure. The mounting block has a circular groove, and the circular structure is fitted into the circular groove. The lower end of the mounting block is set in the first limiting cutout of the needle plate. The mounting block moves within the first limiting cutout. The upper end of the mounting block is connected to the lower side of the small needle plate, and the lower end of the mounting block is connected to one side of the toothed plate mounting plate. The drive motor drives the eccentric wheel to make the eccentric wheel track arm reciprocate, driving the mounting block. The mounting block simultaneously drives the small needle plate and the toothed plate mounting plate. The small needle plate is linked to the sinker plate, and the toothed plate mounting plate is linked to the toothed plate.

[0016] The beneficial effects of this invention are as follows: When any needle in the mirrored needle group exits, the damping steel wire prevents the needle from exiting due to mutual friction, ensuring the flatness of the fabric; the control motor drives the lever arm, which in turn drives the mounting block, which in turn drives the small needle plate and the toothed plate mounting plate. The small needle plate is linked to the sinker plate, and the toothed plate mounting plate is linked to the toothed plate, allowing the sinker plate and the toothed plate to make synchronous fine adjustments. When the machine head moves left or right once, the toothed plate and the sinker plate also move accordingly once, preventing the expansion spring from rubbing against the needle when it rises to the shifting height. The shifting and turning of the needle is more stable and reliable. At the same time, it effectively increases the space between the needle and the sinker plate and the toothed plate, so that the loops of the woven fabric will not be squeezed and torn due to the "narrow" space between the needle and the sinker plate and the toothed plate. The yield rate is high, and the knitting speed can be further improved, thereby improving the economic efficiency of the machine. Attached Figure Description
