Electro-pattern sewing machine

Abstract

The invention belongs to the technical field of sewing machines and relates to an electro-pattern sewing machine. The electro-pattern sewing machine comprises a rack, a machine head, a feeding mechanism and a controller, wherein longitudinal slideways located at the rear side of the needle size are fixed on both sides of the machine head, a front cross beam is hung on the front ends of the longitudinal slideways, the front cross beam is internally provided with a transmission device, a feeding seat is fixed on the transverse movement part of the transmission device, the front end of a spline shaft is connected with the transmission device, the middle of the spline shaft is sleeved in a longitudinal guide hole of a mounting plate, a bull gear is sleeved on the spline shaft, a pinion which is in meshing transmission with the bull gear is driven by a driving motor, a lengthened cushion block is fixed between the bottom plate of the machine head and a rear cross beam, synchronous belt pulleys are fixed on the bottom plate of the machine head and both sides of the rear cross beam respectively, synchronous belts are sleeved on the synchronous belt pulleys, the front end of a transmission arm which is arranged longitudinally is fixed on the front cross beam and the rear end of the transmission arm is clamped on the transmission belts which are arranged longitudinally. The electro-pattern sewing machine has the following advantages: the machine is suitable for multistation feeding.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, in particular to an electronic pattern sewing machine. Background technique [0002] At present, the general electronic pattern sewing machines are mostly composed of a frame, a head fixed on the frame, a feeding mechanism for feeding materials on a two-dimensional plane, and a controller. The controller automatically controls the machine head according to the set program. However, in practice, it is found that the existing electronic pattern sewing machine has the following deficiencies: the first is that the horizontal feeding device at the front of the head of the feeding mechanism is exposed on the outer surface of the body, which is not only easy to scratch and pollute the fabric, and it is also easily polluted by dust; the second is that the longitudinal feeding mechanism of the electronic pattern sewing machine is set under the feeding platen, which makes the structure of the trans...

The controller automatically controls the machine head according to the set program. However, in practice, it is found that the existing electronic pattern sewing machine has the following deficiencies: the first is that the horizontal feeding device at the front of the head of the feeding mechanism is exposed on the outer surface of the body, which is not only easy to scratch and pollute the fabric, and it is also easy to be polluted by dust; the second is that the longitudinal feeding mechanism of the electronic pattern sewing machine is set under the feeding platen, which makes the structure of the transmission and driving mechanism complicated and inconvenient to maintain; the third is the movement of the longitudinal feeding mechanism and the horizontal feeding mechanism. The distance is too short, not suitable for multi-station feeding
