Abstract

The utility model relates to an automatic lubricating device for a curved stitch seam type sewing machine. The utility model comprises a lower oil pan acting as a chassis of a machine body simultaneously, an upper oil pan installed at the upper part of the machine body, an oil pump, an oil pipe and a reflux pipe, wherein oil in the upper and the lower oil pans is formed into circulatory flow by the oil pump, the oil pipe and the reflux pipe. A lubricating pipe for lubricating all the mechanisms is connected to the upper oil pan. The oil pump sucks the oil from the lower oil pan to the top of the upper oil pan. The purpose of automatically oiling and lubricating the components of the machine body is realized by a position drop height between the upper oil pan and the mechanisms. The utility model is especially suitable for being installed on curved stitch seam type sewing machines, such as loctal stitch seam, or zigzag stitch seam, or ornamental seam of sinuosity seam, or connecting bar take-up, etc.

Description

The Zigzag sewing machine automatic fuelling device

The utility model relates to the automatic fuelling device of a kind of parts of Sewing machines, particularly Zigzag sewing machine.

The tortuous seam of existing GG type zigzag linear slit, the Sewing machines as lock-type chain stitch, zigzag stitching, the tortuous ornamental linear slit of seam or connecting rod take-up, shank swing etc. when lubricated each parts, mechanism, does not all have the automatic oiling function, but adopts the method for manual oil dripping; Therefore, exist lack of lubrication, uneven phenomenon when lubricated, cause the Sewing machines rotating speed not high, noise, vibration are excessive, simultaneously service life of a machine are shortened greatly.

The purpose of the utility model is on the basis of original tortuous Sewing machines, has added the automatic oiling function, thereby has improved the rotating speed of Sewing machines, reduces noise, vibration, prolongs machine service life.

The technical solution of the utility model is achieved in that it comprises the lower oil pan on double as body chassis, is contained in the upper oil-pan of body upper, the oil in the upper and lower food tray is formed oil pump, oil pipe and the return duct that circulates; Be connected with lubricated lubrication management on the upper oil-pan to each mechanism.Because the position of upper oil-pan is higher than the position of each lubricating structure, so lubricating oil is lubricated and heavy of the excessive oil after lubricated or get back to lower oil pan by oil return pipe by lubrication management reddendo signula singulis mechanism.

Oil pump of the present utility model can be contained in the lower shaft of Sewing machines, also can be contained on the vertical shaft of Sewing machines, and transmit the drive oil pump by gear.

Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.

Fig. 1 is that the utility model is installed in the schematic diagram on the Sewing machines.

Fig. 2 is that the P of Fig. 1 is to schematic diagram.

Fig. 3 is that the K of Fig. 1 is to schematic diagram.

Fig. 4 is that oil pump is installed in the schematic diagram on the Sewing machines vertical shaft.

Fig. 5 is a gear-driven schematic diagram between oil pump and the lower shaft.

Referring to Fig. 1, Fig. 2, Fig. 3, the Zigzag sewing machine automatic fuelling device comprises lower oil pan 5, is contained in the upper oil-pan 2 on body 1 top, and the oil in the upper and

lower food tray

2,5 is formed oil pump 7, oil pipe 4 and the return duct 3 that circulates.

Lower oil pan 5 is made the chassis that matches with body 1 bottom size, shape; Upper oil-pan 7 is made disk-like structure, and diapire is provided with the lubrication management 6 of return duct 3 and each mechanism components of number Zhi Liuxiang; Upper oil-pan 7 also can be made tubular.Return duct 3 also can be installed on the head part, so that lubricating oil returns lower oil pan 5 from the head upper reaches.Oil pump 7 is contained on the lower shaft 8 or vertical shaft 10 in the body 1, referring to Fig. 4, Fig. 5, comes transmission by gear 9 between oil pump lower shaft 8 or the vertical shaft 10.

The utility model operation principle is such: oil pump 7 is by the drive of arbor (lower shaft 8 or vertical shaft 10), oil is drawn into upper oil-pan 2 from lower oil pan 5, by the position drop of upper oil-pan 2 with each lubricating structure, the oil part of upper oil-pan 2 flows to each parts of body by lubrication management 6 and carries out oily, oil behind excessive oil on the upper oil-pan 2 and each component lubrication flows back to lower oil pan 5 by oil return pipe 3, thereby realizes the purpose of automatic oiling.

Obviously, the utlity model has simple in structure, easy for installation, under the situation that Sewing machines is not changed or changes seldom, can realize purpose, thereby improve the rotating speed of Sewing machines, reduce the noise of machine the self-oiling of each parts in the body, prolonged the service life of machine, be particularly suitable for being installed on various types of Zigzag sewing machines.
