Abstract

The invention belongs to the technical field of sewing machines, and particularly relates to a double-needle vertical sewing machine. The double-needle vertical sewing machine comprises a base, a machine body is fixed to the top of the base, a second guide groove is formed in one side of the top of the base, a second guide block is slidably connected into the second guide groove, a chassis is fixed to the top of the second guide block, and a lower clamping plate is rotatably connected to the top of the chassis. A vertical plate is fixed to the top of the lower clamping plate, a first sliding groove is formed in the inner side of the vertical plate, a first sliding block is slidably connected into the first sliding groove, a first spring is fixed between the first sliding block and the inner wall of the first sliding groove, the vertical plate is sleeved with an upper clamping plate, the upper clamping plate and the first sliding block are fixed, and a holding disc is fixed to the top of the upper clamping plate. According to the double-needle vertical sewing machine, the holding disc is held for pressing, the upper clamping plate is driven to move downwards along the first sliding groove along with the first sliding block, cloth is clamped, after the sewing machine is started, the holding disc is pushed towards the rear end, the cloth can be sewn along a straight line, and meanwhile the situation that a hand gets close to the needle position, and accidental injuries are caused can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a double-needle vertical sewing machine. Background technique [0002] Double-needle sewing machine (also called double-needle flat car) is a commonly used sewing machine with two needles, two synchronizations, three synchronizations, and the corner sewing effect is that the double threads are juxtaposed and parallel to each other. But it is indispensable. Although the flat car can sometimes replace the double needle, considering the efficiency, use the flat car to do the work of the double needle in mass production, unless it is a small amount of production, the double needle is efficient, and the double lines are parallel and neat. [0003] When the existing sewing machine is in use, it is necessary to press the cloth to be sewn with one hand and drag the cloth to complete the sewing process. This method has the following problems. The sewing route is difficult to move ...
