Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a five-line serging machine. Referring to fig. 1, the five-line serging machine includes a base 1, a machine body 2 fixed on the base 1, and a vertical needle 21 provided below one end of the machine body 2. The front side and the rear side of the needle 21 are provided with leveling mechanisms for tensioning and leveling cloth, and the leveling mechanisms comprise a leveling component 3 arranged in front of the needle 21 and a tensioning component 4 arranged behind the needle 21.

The cloth is moving to eedle 21 in-process, through flattening subassembly 3, flattening subassembly 3 flattens the fold on the cloth at the cloth removal in-process, and the cloth reaches tensioning subassembly 4 through the one end of eedle 21 simultaneously, and tensioning subassembly 4 makes the cloth stretched by the tensioning for the fold on the cloth is levelled, conveniently flattens the work of flattening of subassembly 3, and the mechanism of flattening from this levels the cloth, makes the sewing stitch seam clear orderly.

Referring to fig. 1 and 2, the flattening assembly 3 includes a groove 31 disposed at the edge of the base 1, one end of the groove 31 is hinged to a pressing rod 32 disposed in the same vertical plane as the groove 31, the pressing rod 32 is sleeved and rotatably connected to a pressing roller 33, and the other end of the pressing rod 32 is detachably connected to the other side of the base 1. When the pressing rod 32 rotates to be parallel to the upper surface of the base 1, the pressing roller 33 is located in the groove 31, a certain gap exists between the pressing roller 33 and the groove 31, and the upper surface of the pressing roller 33 is lower than the upper surface of the base 1.

Referring to fig. 2 and 3, a fixing block 34 is fixed to the other end of the groove 31, and a fixing pin 35 passes through the fixing block 34. The other end of the pressing rod 32 is provided with a through hole 321, and the fixing pin 35 simultaneously penetrates through the base 1 and the through hole 321 of the pressing rod 32 so as to fix the pressing rod 32. The upper end of the groove 31 close to one side of the needle 21 is set to be a round angle.

When cloth needs to be placed, the fixing pin 35 is pulled out of the through hole 321, so that the pressing rod 32 is detached from the base 1. The pressing rod 32 is rotated to enable the pressing rod 32 to be far away from the base 1, then one end of the cloth is placed on the base 1 to be laid flat, the pressing rod 32 is rotated back again, and two sides of the cloth are enabled to be respectively abutted against the upper surface of the base 1 and the lower surface of the pressing roller 33. The fixing pin 35 is then inserted into the through hole 321 again, and the pressing rod 32 is fixedly connected with the base 1 again, so that when the cloth passes between the pressing roller 33 and the upper surface of the base 1, the pressing roller 33 flattens the wrinkles on the cloth, and the cloth is quickly and effectively flattened.

The pressing rod 32 and the pressing roller 33 are lower than the upper surface of the base 1, so that the cloth is wound on the pressing roller 33 partially, the contact area between the pressing roller 33 and the cloth is increased, and the cloth is flattened. When the cloth breaks away from compression roller 33, the opposite side butt of cloth is on the fillet of recess 31 for the cloth is again through the process of flattening on the fillet, and fold or unevenness on the reduction cloth, the fillet is more smooth simultaneously, reduces the resistance to the cloth removal.

Referring to fig. 4, an arc-shaped isolation cover 36 wrapping the pressing roller 33 and the groove 31 is arranged outside the groove 31, and T-shaped sliders 361 are fixed at two ends of the isolation cover 36. Referring to fig. 1, sliding grooves 362 (see fig. 3) for inserting sliding blocks 361 are formed in two sides of a base 1, the sliding blocks 361 on two sides of a shielding case 36 are inserted into the sliding grooves 362, so that the pressing roller 33 is separated from the outside by the shielding case 36, when a worker sews cloth, the arm can be placed on the base 1, the arm cannot contact with the pressing roller 33 under the separation of the shielding case 36, and meanwhile, the pressing roller 33 cannot be blocked when the cloth is pressed.

Referring to fig. 1 and 2, the tension assembly 4 includes a tension rod 41 disposed above the base 1 and parallel to the pressing roller 33, and both ends of the tension rod 41 are rotatably connected to the base 1. One end of the tension rod 41 is fixedly connected with a driving motor 42 fixed on the base 1, and a plurality of evenly distributed bulges 43 are fixed on the circumferential surface of the tension rod 41.

The cloth passes the back from the eedle 21 below, passes again between tensioning rod 41 and the base 1 upper surface, and tensioning rod 41 supports tight cloth on base 1, and the friction on arch 43 increase tensioning rod 41, and driving motor 42 drive tensioning rod 41 rotates, and tensioning rod 41 drives the cloth translation at the rotation in-process, thereby the cloth of cloth rear end is pulled by the cloth of front end and is evened up the cloth tensioning.

The implementation principle of a five-line serging machine of the embodiment of the application is as follows: pulling out the fixing pin 35, rotating the press roller 33 to separate from the groove 31, then placing one end of the cloth on the base 1, rotating the press roller 33 back to the groove 31 again and pressing against the cloth, and pulling the cloth to pass below the needle 21 and between the tension rod 41 and the base 1;

the driving motor 42 drives, the tension rod 41 rotates, so as to drive the cloth to move, and the cloth is tensioned and leveled while moving and is simultaneously flattened by the press roll 33.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
