Technical Field

[0001] The utility model belongs to the technical field of template machines and relates to an oil injection device on a rotary template machine. Background Art

[0002] The rotary template machine is the main equipment for opening pockets on clothing and is widely used in the clothing manufacturing industry. The rotary template machine installs the shuttle seat on the rotating table, and the rotating table drives the shuttle seat to rotate clockwise or counterclockwise. The rotary shuttle seat is equipped with an oil tank for containing sewing machine oil. During the movement, the shuttle seat will generate a certain amount of centrifugal force, which indirectly drives the sewing machine oil in the oil tank in the shuttle seat to move. At the same time, a relative force will be generated when the rotating table stops. Under the action of these two forces, the sewing machine oil in the oil tank in the shuttle seat will turn over and over and be thrown out from the oil filling hole. In view of this, it is necessary to develop an oil filling device that can prevent the sewing machine oil from being thrown out from the oil filling hole without affecting the oil filling of the oil tank.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings. Figure 1-4 :

[0021] An oiling device on a rotary template machine comprises a hook seat 2 mounted on a rotary table 1, wherein an oil tank 3 is arranged inside the hook seat 2, and the oil tank 3 is filled with sewing machine oil, an oiling platform 4 connected to the oil tank 3 is arranged outside the oil tank 3, a mesh rubber ring 5 is arranged inside the oiling platform 4, the mesh rubber ring 5 comprises a rubber ring 6 and a metal mesh 7, the rubber ring 6 is interference fit with the inner hole of the oiling platform 4, and the metal mesh 7 is arranged on the inner side of the rubber ring 6 and covers the inner hole thereof.

[0022] When working, refer to the attached Figure 3 The rotating table 1 drives the hook seat 2 to rotate, and the rotation of the hook seat 2 drives the sewing machine oil in the oil tank 3 to move. A very small part of the sewing machine oil will be thrown to the oil filling platform 4 as the hook seat 2 rotates, and hit the metal mesh screen 7 through the inner hole of the oil filling platform 4, and then flow back to the oil tank 3. The mesh screen rubber ring 5 in the oil filling platform 4 can effectively prevent the sewing machine oil from being thrown out.
