Safety protection device and method for tilting operation of machine head of sewing machine

Abstract

The invention relates to a safety protection device and method for the tilting operation of a machine head of the sewing machine. The machine head of the sewing machine can be arranged on a table top in a mode of being capable of being overturned in the length direction of the machine head; the safety protection device comprises at least one stand column which is arranged on the table top and used for supporting the overturned machine head; the stand columns are located behind the machine head; the machine head is overturned backwards; backward turning positioning support is formed under the support of the stand columns; the safety protection device further comprises a locking piece which is arranged on the machine head or / and the table top and can enable the machine head and the table top to form self-locking; the machine head and the table top are relatively separated until the locking piece loses limitation of the machine head or the table top and is freely triggered; and if the machine head rotates, the locking piece forms self-locking. When the machine head is subjected to the tilting operation, effective supporting is formed through the stand columns, and uncontrolled rotation of the machine head is prevented under the release of the locking piece and the formation of effective self-locking protection, the safety of the tilting operation of the machine head is improved, and the equipment damage rate caused by accidental overturning is avoided.

Description

technical field [0001] The invention belongs to the field of sewing machines, in particular to a safety protection device for tilting operation of a sewing machine head, and also relates to a tilting operation method of a sewing machine head. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. It is convenient for the operator to maintain or overhaul the sewing machine. The existing sewing machine is generally reversibly set on the table, so that the operator can perform related operations on the bottom of the sewing machine. [0003] However, in the actual operation process, due to the lack of safety devices in the existing sewing machines, when the head of the sewing machine is turned over to the tilted state suitable for the operation of the operator, the head is prone to uncontrolled rotation accidents, which seriou...

Problems solved by technology

[0003] However, in the actual operation process, due to the lack of safety devices in the existing sewing machines, when the head of the sewing machine is turned over to the tilted state suitable for the operation of the operator, the head is prone to uncontrolled rotation accidents, which seriously threatens the safety of the operator. It is safe, and due to the high precision requirements of the sewing machine itself, collisions can easily cause damage to the internal parts of the sewing machine and cause losses
