Description

Automatic non-yarn bottom lifting device

Technical Field

The invention relates to the technical field of computerized flat knitting machines, in particular to an automatic non-yarn bottom lifting device.

Background

At present, a bottom plate lifting device of a computerized flat knitting machine mainly comprises a composite needle, a composite needle opening and closing structure, a bottom lifting small needle plate, a lifting mechanism and a motor for driving the bottom plate to move up and down. The specific control mode is as follows: rely on compound needle with the coil lock in the slot, make the start-up bottom plate provide the pulling force to weaving the piece downwards, will weave the piece and draw when the closed back roller of roller cloth roller can normally the tractive weave piece of roller cloth roller, compound needle is released the rubber band of lock in the hook groove, the end-lifting device is to the reset position downwards, thereby accomplish end-lifting work, consequently can reduce and weave the produced yarn waste in the process, practice thrift manufacturing cost, say that above-mentioned end-lifting device can be in order to practice thrift the yarn waste quantity and improve work efficiency, but still have the problem that needs few end-lifting yarn in practical application, the cloth piece of weaving down needs the problem of artifical end-lifting yarn, work efficiency has been influenced.

When the existing hand-operated flat knitting machine starts knitting, the threading plate is inserted into gaps of front and rear needle beds of the flat knitting machine from bottom to top, then a steel wire is manually passed through a needle ring at the top end of a needle tooth on the threading plate, the starting on the threading plate forms a closed state, the starting of the flat knitting machine is realized, the starting mode does not consume starting yarns, and the requirement of yarn starting can be met. However, in the actual application process, the threading plate needs to be manually threaded with steel wires, a large amount of manpower is consumed, and the full-automatic bottom-lifting function cannot be realized. The following steps are repeated: the invention patent with the publication number of CN207958632U discloses a structure of a bottom lifting device. The bottom raising device mainly comprises a bottom raising comb, a sealing wire, a lifting mechanism and a wire feeding mechanism, wherein the sealing wire is controlled by the wire feeding mechanism to penetrate into the bottom raising comb. The lifting mechanism enables the bottom comb to move downwards to provide tension for the knitted piece, after the knitted piece is pulled to the cloth roller to normally draw the knitted piece, the wire feeding mechanism draws out the locking wire, and the computerized flat knitting machine normally knits the knitted piece. Therefore, the effect of no waste yarn starting like a hand flat knitting machine can be achieved, and the production cost is saved.

The bottom lifting device matched with the computer flat knitting machine can save waste yarn and improve work efficiency, but the following technical problems are often exposed in the actual use process:

one is as follows: the sealing wire is fed into the bottom lifting comb in a mode of clamping the sealing wire by two wire feeding wheel surfaces. However, the phenomenon that the lock wire and the wire feeding wheel are not delivered in place due to slipping frequently occurs in actual operation, so that a large amount of knitting needles of the flat knitting machine are damaged during bottom rising.

The second step is as follows: the wire feeding wheel can not be out of the electric control alarm when slipping during the sealing lock wire drawing.

And thirdly: the long-time grinding of the wire feeding wheel and the sealing wire causes the deformation and the grinding breakage of the sealing wire, and the cloth of the bottom lifting device cannot be normally removed.

Fourthly, the method comprises the following steps: because the lifting device adopts a double-motor lifting structure, the problem that the lifting comb is higher at one side and the other side when the lifting device is lifted and lowered frequently occurs, the weaving quality and the lifting effect are influenced, and the production cost is high, and the installation difficulty is high.

And fifthly: the lifting device adopts a double-track motion design, the production cost and the installation difficulty are high, and the knitting piece thread end of the previous piece can be hung on the bottom lifting comb after the bottom lifting comb is reset to cause the next bottom lifting difficulty.

Based on the technical problems, most of computerized flat knitting machine manufacturers are reluctant to weave pieces by adopting a method without waste yarn bottoming, and continue to use the original method of hooking rubber bands to perform bottoming or the original method of pulling waste yarns.

When the steel wire contacts the in-place signal, the machine head can continue to weave according to the pattern, and when the threading plate descends to the cloth releasing position. The electric control system controls the wire drawing and feeding device and simultaneously controls the wire winding motor H1 to rotate clockwise to drive the circular wire winding disc H11 and the zero-position driving gear H6 which are installed on the motor to rotate, the zero-position driving gear can drive the zero-position sensing wheel H7 to rotate, when the zero-position sensing wheel rotates to the position of the sensor H5, the motor stops rotating, when the wire drawing motor rotates, the wire winding disc simultaneously rotates to draw a steel wire, if the friction force of yarns is greater than the friction force of the wire drawing clamping wheel and the steel wire during wire drawing, the steel wire cannot be drawn, the wire drawing disc can assist in drawing the steel wire to move to the zero position, and then the next step of action is carried.

The invention relates to an automatic non-yarn bottom lifting device, which is characterized in that a steel wire in-place signal and a steel wire reset signal are respectively arranged on two sides of a threading plate A; the lifting device B is controlled by a single motor and arranged in a single-rail lifting mode; the wire feeding device G adopts a reciprocating type push-pull steel wire structure; the winding device H adopts a disc type rotating device; the novel multifunctional electric heating furnace is convenient to use and rapid to operate, and greatly improves the working efficiency.

The above description is only a preferred embodiment of the present invention, and all equivalent changes or modifications of the structure, characteristics and principles described in the present invention are included in the scope of the present invention.
