Modularity and flexibility of leather sewing machines meet sofa presser standards

Leather sewing machine compared to ordinary sewing machines require more intensive work, some leather products for sewing machine performance and sewing line has certain requirements. For example, the automotive industry is faced with ever-changing fashion trends, including styles, colors, materials, and so on. Manufacturers of car seat covers and car interior parts must be very flexible and able to put new designs into practice. its modularity and flexibility can help them meet these requirements. If the existing technology does not fully satisfy them, we work closely with our customers to develop an individual sewing solution together.

The spindle machine drives the needle to move up and down, the spindle motor rotates once, and the needle goes up and down once, to realize the felting fabric sewing: the X-axis and Y-axis motors drive the feeding frame to move left and right, forward and backward, to locate the position; through the feedback signal of the spindle motor encoder to determine the permissible feeding interval, in the permissible feeding interval X-axis and Y-axis motors can only move, in this way, to realize the synchronization of the felting fabric and the feeding material.

The working process of the control system of the pattern machine: the pattern graphic is patterned (including straight line, arc, polygon, curve, etc.), and the patterned lines are divided and calculated according to the sewing stitch length, sewing speed, sewing process, etc., and the sewing data are generated automatically. The motion control card converts the sewing data into specific control instructions (including pulse, direction, I/O, etc.) to control the spindle, X-axis, and Y-axis motor operation of the pattern machine, as well as I/O auxiliary control.

Leather sewing machine use process will often cause some problems. For example, it can not be started normally when the machine is turned on, indicating that its power supply components may be faulty, at this time we summarize a few points of failure stemming from the solution, for reference only:

◆ Can not touch the limit switch This time promote the taut frame or head machine base to make the limit switch reset.

◆ If the limit switch or motor off button is damaged at this time you need to check whether the switch button is damaged.

◆ The AC contactor is damaged, it is necessary to replace the AC contactor.

◆ The machine is strong in the box, to prevent rust, coated with rust-resistant grease, due to storage and transportation, which may cause hardening of grease and accumulation of dust, the surface of the grease must be cleaned with gasoline before use, and dry with clean cotton gauze or soft cloth.

◆The machine must be filled with sewing machine oil at all oil holes before an operation, and then the empty car for a test run. The direction of rotation of the handwheel is counterclockwise (the operator faces the handwheel). The machine should be refilled with lubricating oil from time to time during normal use, not less than twice per shift.

◆The working speed of the machine varies according to the operator's proficiency, after the installation of the new machine, there should be a period of low-speed break-in phase, according to 800 rpm running for a month, and then accelerate to the rated speed, but not more than 1000 rpm, so as not to cause damage to the machine parts due to high speed, affecting the service life of the machine.

Scope of application of leather Sewing Machine: It is suitable for sewing heavy-duty sewing machines for heavy-duty sewing of canvas and leather products such as truck sails, load bags, safety belts, saddles, bags, and other heavy-duty sewing products.
