Carpet overedge machine head

Abstract

The invention discloses a carpet overedge machine head, which comprises a cabinet, a base, a transmission crankshaft, a needle plate, cloth feeding teeth, a needle, an upper bent needle, a lower bent needle, an upper threading device and a lower threading device. A baffle capable of adjusting the edge width is arranged on the cabinet; a belt pulley matched with the transmission crankshaft, an oil inlet, a needle pitch adjuster and the lower threading device are arranged on a side surface of the cabinet; the needle plate and the cloth feeding teeth are arranged on an upper end face of the cabinet; the cloth feeding teeth are matched with the needle plate; the needle is matched with the transmission crankshaft through a needle clamp and a telescopic rod; the upper and lower bent needles are connected with the transmission crankshaft respectively and are in synchronous cross motion; the upper threading device, a presser foot lifter device and a presser foot are arranged on the base; and the presser foot is matched with the needle plate and the cloth feeding teeth. The invention has the advantages that: the carpet overedge machine head is simple in structure, the base occupies small space, and radian leathers and thread fabrics have an enough movable space in the process of sewing the radian leathers and thread fabrics; and the upper and lower threading devices are provided with matched thread releasing devices so as to be convenient to use.

Description

technical field [0001] The invention belongs to the technical field of sewing equipment, in particular to a head of a carpet hemming machine. Background technique [0002] Carpet hemming machines are mainly used in the market to sew the edges of thread fabrics such as leather, carpets, and blankets. The base of the existing carpet hemming machine is relatively large and is equipped with a presser foot lifting rod, which is connected with a pedal through a chain to make the presser foot lift and press. The disadvantages are: complex structure, The base takes up a lot of space, so the space behind the machine head is limited. When sewing some curved leather and thread fabrics (such as foot pads for automobiles), the base or chain will take the leather and thread fabrics. The active route is blocked, so it is impossible to complete the sewing of some curved and long-length leather and thread fabrics; moreover, there is no unthreading device installed on the head of this hemmin...

Problems solved by technology

The base of the existing carpet hemming machine is relatively large and is equipped with a presser foot lifting rod, which is connected with a pedal through a chain to make the presser foot lift and press. The disadvantages are: complex structure, The base takes up a lot of space, so the space behind the machine head is limited. When sewing some curved leather and thread fabrics (such as foot pads for automobiles), the base or chain will take the leather and thread fabrics. The active route is blocked, so it is impossible to complete the sewing of some curved and long-length leather and thread fabrics; moreover, there is no unthreading device installed on the head of this hemming machine, and the user needs to complete the hemming after hemming. Pulling the silk thread by hand requires a lot of strength because the thread is in a tight state. If you are not careful, you may be cut by the thread. This brings a lot of inconvenience to the use, so it is necessary to improve
