Flatcar sewing machine provided with lifting machine head

Abstract

The invention discloses a flatcar sewing machine provided with a lifting machine head. The machine comprises a machine table, a flatcar sewing machine body arranged on the machine table as well as a flatcar sewing machine head connected with the flatcar sewing machine body through a lifting mechanism, wherein the flatcar sewing machine head perpendicularly moves up and down relative to the flatcar sewing machine body under the control of the lifting mechanism, so that a knitting mechanism in the flatcar sewing machine head and a transmission mechanism in the flatcar sewing machine body are in a separated state or a linked state. When the flatcar sewing machine stops working, the machine head is upwards lifted, so that large space is reserved between a machine needle and a table surface, sufficient space is provided for treatment of fabric on the table surface in the working process of an operator, the problem that the fabric is snagged and the machine needle is even broken due to the fact that the machine needle easily hooks the fabric because of too small distance between the machine needle and the table surface is solved, and the working efficiency of the operator is effectively improved. Besides, the flatcar sewing machine provided with the lifting machine head is simple in structure, occupies small space, is low in manufacturing cost and is suitable for wide application.

Description

technical field [0001] The invention relates to the technical field of flat car sewing machines, in particular to a flat car sewing machine with a lifting head. Background technique [0002] Flat car sewing machines have been widely used due to their mature technology and low price, but there are many problems in existing flat car sewing machines. The structural characteristics and working principle of existing flat car sewing machines determine that the needles of flat car sewing machines need to be close to the table, In the parking state, the space between the needle and the table is not large, and the distance between the needle and the table is too small to cause the fabric to be hooked to the needle when the flatbed sewing machine is in use, which will cause the fabric to be hooked and be damaged seriously. Some even cause the needle to break, and this problem in turn forces the operator to be careful when using the flat car sewing machine, which greatly reduces work e...
