Head structure of embroidery machine of towel

Abstract

The invention discloses a head structure of an embroidery machine of a towel. The head structure comprises a housing, and a needle bar and a small presser bar both mounted in the housing; the needle bar and the small presser bar are arranged at an interval; the needle bar and the small presser bar both are capable of moving up and down and connected with driving mechanisms I and III, respectively; the needle bar is also capable of rotating and connected with the rotating driving mechanism; the driving mechanism I comprises a cam I connected with a power shaft, a rocking arm I connected with the cam I, a rocking bar I connected with the rocking arm I and a returning spring I; the rocking bar I is connected with the needle rod; and the middle of the rocking arm I is hinged in the housing. As the needle bar, the large presser bar and the small presser bar of the head structure of the embroidery machine are separated from one another without sleeving one another, the mechanical structure is simplified, the fault rate of the machine is reduced and the service life of the machine is prolonged. Furthermore, according to the head structure of the embroidery machine, the return spring is adopted for returning so that the surface of the rocking arm can be always against the surface of the cam without harsh takh sound, and therefore, the noise of the machine is reduced and the influence on the body health of workers is avoided; and in short, the head structure is more humanized.

Description

technical field [0001] The invention relates to a towel embroidery machine, in particular to a head structure of the towel embroidery machine. Background technique [0002] In the prior art, the machine head on the existing ordinary computerized towel embroidery machine uses a cam structure to drive the needle bar and the presser foot bar, and there is a relatively intense impact between the cam surface and the transmission rod, resulting in relatively loud noises , causing noise pollution. Further, the needle bar and the presser foot bar in the machine head are all nested together, so that the machine structure is relatively complicated, the price and cost are high, and the technical requirements for production personnel are relatively high. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a towel embroidery machine head structure with simple structure, low failure rate and low noise. [0004] The technic...

Problems solved by technology

[0002] In the prior art, the machine head on the existing computerized towel embroidery machine uses a cam structure to drive the needle bar and the presser foot bar, and there is a relatively intense impact between the cam surface and the transmission bar, resulting in relatively loud noises , causing noise pollution

Furthermore, the needle bar and the presser foot bar in the machine head are all nested together, which makes the machine structure more complicated, the price and cost are high, and the technical requirements for production personnel are relatively high.
