The principle of the invention is illustrated as follows:

the design provides a device and a method which can carry out multiple sewing track making on the same cloth without influencing cloth positioning, and simultaneously provides a new needle rod push-pull device, thereby solving the problem that the needle rod is deformed due to the collision of the existing push-pull box and the needle rod, optimizing the structure of a template machine and improving the service efficiency of a universal template.

The operating principle of the triangular push-pull box in the prior art is as follows: when the needle bar is accommodated, the oblique side of the triangular push-pull box generates oblique pressure on the needle bar, so that the needle bar moves along the side wall of the triangular box, thereby achieving the purpose of resetting the needle bar track. This design utilizes electric putter to promote the push pedal and will disorderly needle bar unified one side that promotes the push-and-pull box to in the location to the needle bar, thereby the required sewing orbit of more convenient preparation.

The needle bar is provided with a rubber head at one end, which contacts and fixes the cloth when bending, and a positioning column at the other end, which is composed of a long bolt and a nut and used for positioning the needle bar.

The cloth pressing structure is mainly realized by a cloth pressing plate which is connected to the moving plate through a cloth pressing spring, and rubber pads are uniformly distributed on the cloth pressing plate and used for increasing the friction force between the cloth pressing plate and cloth, so that the cloth is not easy to loosen on the template, and the cloth sewing track is accurately positioned. The length of the movable plate is consistent with that of the template, the movable plate is provided with a positioning hole, and when the movable plate moves to a required position on the template, the movable plate can be fixed on the template through the positioning hole on the movable plate and the sliding groove on the template by using bolts and nuts.

An inclined chute for the fixed rod to move is arranged on the lower template, and two limit blocks are arranged on the fixed seat, so that a gap is formed between the two limit blocks, and the fixed rod can be inserted into the gap; after the track of the template is manufactured, the transverse moving assembly is driven to move the limiting blocks to the positions of the fixing rods, the longitudinal moving assembly is driven to enable the fixing rods to be inserted into the gaps of the two limiting blocks, and then the transverse moving assembly is driven, so that the fixing of the needle rod on the lower template can be completed.

The pressing rod plate is connected to the connecting plate through a pressing rod spring, the pressing rod plate is lifted by the pressing rod spring in a natural state and cannot apply pressure to the needle rod, the moving motor is aligned to the flange of the electromagnetic clutch, at the moment, the electromagnetic clutch works to enable the electromagnetic clutch to be connected with the flange of the electromagnetic clutch, the driving motor rotates, the flange of the electromagnetic clutch can drive the cam on the same rotating shaft to rotate when rotating, and the pressing rod plate can move towards the needle rod after the excircle of the cam is contacted with the pressing rod plate, so that the pressing rod plate presses the needle rod group downwards to achieve the purpose of pressing the needle rod; when the needle bar group which is moved to form the sewing track is pressed tightly, namely the sewing track of the universal template is determined, when the electromagnetic clutch flange is rotated again, the excircle of the cam leaves the pressure lever plate, the pressure lever plate is lifted under the tension of the pressure lever spring, no pressure is applied to the needle bar, the needle bar group is released, and the next sewing track can be established again.

To reset the disordered needle rods, the longitudinal moving assembly moves the push-pull box towards the template until all the needle rods are received in the push-pull box, then the longitudinal moving assembly is controlled to stop moving, and then the electric push rod is controlled to push the push plate to push all the needle rods to one side of the push-pull box, so that track making can be started. The transverse moving component is controlled to drive all the needle rods to reach the first needle rod position, the longitudinal moving component is controlled to move, the first needle rod is moved out of the push-pull box, the first needle rod reaches the set position, then each needle rod is moved in sequence, and after all the needle rods are moved, the track needing sewing is shown at the other end of the needle rod in the universal template.

The transverse moving assembly and the longitudinal moving assembly can be composed of synchronous belts, motors and sliding blocks.

The design can enable one piece of cloth to realize the manufacture of multiple sewing tracks and the track positioning is accurate, and meanwhile, the split track fixing mechanism can change the structures such as a cam, a cloth pressing plate and the like on the fixing mechanism according to the size, the shape, the thickness, the physical performance and the like of the cloth to meet the requirements of various kinds of cloth on pressing force.
