Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the drawings.

[0044] Such as figure 1 As shown, a chain-type bead edge machine includes a mounting frame 1 and a machine head 2 located on the mounting frame 1. A needle mechanism 3 is installed under the head 2 and a matching needle mechanism 3 is installed under the mounting frame 1. The hook thread hooking device 4 and the thread cutting device 5 for cutting yarns. The machine head 2 is also equipped with a thread loosening device 6 and a thread pressing device 7. When the thread loosening device 6 loosens the thread, the thread pressure device 7 compresses the wool to prevent the wool from falling out of the needle mechanism 3.

[0045] Such as figure 2 As shown, the sewing needle mechanism 3 includes a threading needle 8 and a crochet needle 9 side by side, and a space is left between the threading needle 8 and the crochet needle 9.

[0046] Such as image 3 with Figure 4 As shown, th...

Abstract

The invention discloses a chain type manual sewing machine, comprising a mounting rack and a machine head positioned on the mounting rack, wherein the machine head is provided with a stitching mechanism; the stitching mechanism comprises a threading needle and a crochet hook which are arranged side by side; a gap is reserved between the threading needle and the crochet hook; a crochet hook deviceused for cooperating with the stitching mechanism for hooking threads and a thread cutting device for cutting wool are arranged under the mounting rack; the thread cutting device comprises a thread cutting cylinder and a thread cutting piece which is driven to move by means of the thread cutting cylinder. After threading needle of the stitching mechanism carries the wool and passes through cloth,a thread is hooked out by means of the crochet hook after being hooked into a ring shape by means of a thread hooking device; the steps are performed when the cloth is continuously moved, so that thethreading needle just passes through the wool ring hooked by the crochet hook when passing through the cloth downwards, and a chain type stitched edge is further formed. When the thread needs to be cut, the stitching mechanism is stopped when passing through the cloth and the wool ring formed by thread hooking of the thread hooking device; since the wool is not jointed with the stitching mechanism, the thread cutting cylinder drives the thread cutting piece to move, and a thread cutting action is further completed.

Description

Technical field [0001] The invention relates to a sewing machine, in particular to a chain type bead edge machine. Background technique [0002] The chain bead edge machine is a kind of sewing machinery. In the working process of the chain bead edge machine, the straight needle and the crochet needle reciprocate up and down, and then the thread feeding needle is moved away from and close to the crochet needle. The crochet needle is in a plane perpendicular to the movement plane of the thread feeding needle. Make a reciprocating swing. Pass the thread through the thread hole on the straight needle. After the straight needle carries the thread through the fabric on the workbench, the thread feeder pushes the thread in the thread hole to the crochet needle, and the crochet needle passes through the fabric on the workbench. The thread hook on the crochet needle is under the workbench, and a cycle of sewing is completed at this point. [0003] The utility model patent with applicatio...
