Technical Field

The invention relates to sweater knitting mechanical equipment, in particular to a large needle swing arm transmission structure of a sewing machine.

Background

The sewing machine is an important device for sewing the sweater. The linking machine on the market at present mainly has two kinds: one is a common connecting rod linking machine, which has the advantages of simple structure, wide application range, unstable performance and low speed; the other is a high-speed linking machine, which has the advantages of stable performance and high speed, and has the defects that the bevel gear is easy to wear due to the fact that the large needle swing arm uses the bevel gear for transmission, and further, the noise of the machine is increased, and other faults such as wire jumping and the like can be caused.

Disclosure of Invention

The invention aims to overcome the defects of the high-speed linking machine and further provides a method for realizing the left-right swing of a large needle swing arm by replacing bevel gear transmission with synchronous belt transmission.

A big needle swing arm transmission structure of a sewing machine comprises: ride, support, long heart, synchronizing wheel A, synchronizing wheel B, synchronous belt, short heart, bearing frame, round stopper, connecting rod, draw needle ware, swing arm heart, big needle swing arm, long heart one end is passed the ride, and one end is fixed on the support, and the swing arm heart runs through in the support, and the one end at the swing arm heart is fixed to big needle swing arm, draws the needle ware to fix on the swing arm heart characterized by: the bearing seat is fixed on the support, the short center is installed on the bearing seat, the round plug is fixed at one end of the short center and connected with the needle puller through a connecting rod, the synchronizing wheel B is fixed at the other end of the short center, the synchronizing wheel A is fixed on the long center, and the synchronizing wheel A and the synchronizing wheel B are connected through a synchronizing belt.

Preferably, the bearing seat is internally provided with a bearing, and the short center is arranged on the bearing seat through the bearing.

Preferably, the short center is located above the stent parallel to the long center.

Preferably, two ends of the connecting rod are provided with universal bearings which are respectively connected with one end of the needle puller and the outer ring of the round plug plane.

The invention has the advantages that the transmission mode of the large needle swing arm is changed from bevel gear transmission to belt transmission, thereby reducing the noise and failure rate of the machine during operation.

Drawings

FIG. 1 is a structure diagram of a transmission structure of a large needle swing arm

FIG. 2 is a schematic diagram of the transmission of the large needle swing arm

In the figures 1 and 2, A1 big needle swing arm, a 2 swing arm core, a 3 support, a 4 needle puller, a 5 connecting rod, a 6 round plug, a 7 bearing seat, a 8 short core, a 9 synchronous belt, a 10 synchronous wheel, a 11 synchronous wheel, a 12 long core and a 13 trolley table are arranged on A1 big needle swing arm, a 2 swing arm core, a 3 support, a 4 needle puller, a 10 synchronous belt, a 10 synchronous wheel, a 11 synchronous wheel, a 12 long core and a 13 trolley table

Detailed Description

The following further description is made with reference to the accompanying drawings

In fig. 1 and 2, one end of a long core 12 penetrates through a trolley 13 and is fixed on a support 3, a swing arm core 2 penetrates through the support 3, a large needle swing arm 1 is fixed at one end of the swing arm core 2, a needle puller 4 is fixed on the swing arm core 2, a bearing seat 7 is fixed on the support 3, a short core 8 is installed on the bearing seat 7 through a bearing, a round plug 6 is fixed at one end of the short core 8, the round plug 6 is connected 5 with the needle puller 4 through a connecting rod, a synchronizing wheel B10 is fixed at the other end of the short core 8, a synchronizing wheel A11 is fixed on the long core 12, and the synchronizing wheel A11 and the synchronizing wheel B10 are connected through a synchronizing belt 9. When the long core 12 rotates, the short core 8, the round plug 6 and the long core 12 synchronously rotate through the synchronous transmission of the synchronous wheel A11, the synchronous belt 9 and the synchronous wheel B10, because one end of the connecting rod 5 is connected with the plane excircle of the round plug 6, the connecting rod 5 forms an up-and-down motion to be transmitted to one end of the needle drawing device 4 when the round plug 6 rotates, and the needle drawing device 4 transmits the motion to the large needle swing arm 1 through the swing arm core 2 to enable the large needle swing arm 1 to swing left and right.
