Detailed Description
Other technical matters, features and effects of the present invention will become apparent from the following detailed description of preferred embodiments, which proceeds with reference to the accompanying drawings.
The terms "fixed", "installed" or "set" used in describing the combination relationship of the structures disclosed in the specification of the present invention refer to any combination of threads, tenons, fasteners, nails, and adhesives, so that the structures cannot be easily separated or dropped after being combined.
The term "upper" as used in describing the position of a structure as disclosed in the present specification refers to any surface position of the structure and is not colloquially referred to as "above" or "upper" with directionality. The terms "above" and "below" used to describe a structural location refer to the directionality of the conventional use of the lower structural location.
Referring to fig. 1 to 3, there are schematic plan views of the whole and partial structure of the needle protection device of the zipper sewing machine of the present invention, as shown in the drawings, in this embodiment, the needle protection device at least includes a machine body 1, a zipper sewing mechanism 2 and a needle protection mechanism 3;
wherein, the machine body 1 has a base 11 and a machine body 12 installed on the base 11, the machine body 12 is provided with a thread leading mechanism 4, the thread leading mechanism 4 can lead the thread 41 into the zipper sewing mechanism 2 from the outside to provide the sewing requirement (the design of the sewing thread is not the subject of the present invention, and therefore is not repeated);
the zipper sewing mechanism 2 has a zipper cloth guiding frame 21 fixed on the machine base 11, and a sewing needle group 22 fixed on the machine body 12, the sewing needle group 22 has a plurality of hooks 221, in this embodiment, there are two hooks 221, the sewing needle group 22 corresponds to the upper part of the zipper cloth guiding frame 21, each hook 221 can penetrate to the lower part of the zipper cloth guiding frame 21 during sewing operation;
wherein, the needle protection mechanism 3 has a fixed block 31 fixed on the machine base 11, a first supporting rod 32 and a second supporting rod 33 are respectively fixed on the fixed block 31, a first needle protection rod 34 is installed on the first supporting rod 32, a first needle guide surface 341 is formed at the end of the first needle protection rod 34 towards the horizontal direction, a second needle protection rod 35 is installed on the second supporting rod 33, a second needle guide surface 351 is formed at the end of the second needle protection rod 35 towards the horizontal direction, the first needle guide surface 341 and the second needle guide surface 351 correspond to the lower part of the zipper cloth guiding frame 21, and the first needle guide surface 341 and the second needle guide surface 351 are formed towards the opposite direction;
referring to fig. 4 and 5, the zipper 5 to be sewn is installed on the zipper cloth introducing frame 21, when the sewing operation is performed, the respective hooks 221 reciprocate up and down to pass under the fastener cloth introducing frame 21, and when two hooks 221 pass under the fastener cloth introducing frame 21, the first needle guiding surface 341 and the second needle guiding surface 351 can pass by the needle guiding surface, if the hook needle 221 is deviated from the original position during operation, the first needle guiding surface 341 or the second needle guiding surface 351 can effectively guide the hook needle 221 back to the correct position, and each hook needle 221 can be further limited within the effective deviation range when reciprocating, so as to prevent jumping, therefore, when sewing the zipper 5, the machine can be sewn at the correct position of the zipper more correctly, and the finished product of the zipper after sewing is more stable, firm, pull-resistant and neat and beautiful in sewing line.
