Description

Technical Field

[0001] The utility model belongs to the technical field of template machines and relates to a circulating oil tank device for a template machine. Background Art

[0002] As a general-purpose automated sewing device, with the technological innovation and design improvement of template machines, the sewing speed of template sewing machines is constantly increasing. The high-speed rotation of the rotating hook and the rotating hook shaft requires rotating hook oil to reduce friction, dissipate heat, and lubricate. The rotating hook oil plays an important role in the operation of the template machine. There is a common situation in the market that the rotating hook oil needs to be replaced regularly, which is troublesome to operate and causes pollution and waste.

[0003] Chinese Utility Model Patent CN210826672U (publication date: June 23, 2020) discloses a sewing machine and its rotating hook oil supply system, including a pump shaft sleeve. An axially arranged inner hole is provided in the pump shaft sleeve, and a rotating hook shaft passing through the inner hole is arranged in the inner hole. A radially arranged plunger hole is also provided in the pump shaft sleeve, and the plunger hole communicates with the inner hole. A plunger that moves up and down in the plunger hole is arranged in the plunger hole. The rotating hook shaft and the plunger are respectively arranged in the pump shaft sleeve. An eccentric groove eccentrically arranged with the rotating hook shaft is provided on the rotating hook shaft, and the eccentric groove abuts against the plunger. The rotation of the rotating hook shaft drives the plunger to move up and down.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the utility model with specific embodiments in conjunction with the drawings, see Figures 1 - 3 :

[0023] A circulating oil sump device for a template machine includes a shuttle base 1 and a shuttle shaft 2. An oil sump is arranged in the shuttle base 1. A plunger pump 3 is sleeved on the shuttle shaft 2. The oil sump includes a first oil sump 4, a second oil sump 5 and a third oil sump 6 which are arranged in sequence from top to bottom and communicated with each other. The third oil sump 6 includes an upper tank body 7 and a lower tank body 8. The upper tank body 7 is connected to the return oil nozzle 10 of the plunger pump 3 through a return oil pipe 9, and the lower tank body 8 is connected to the inlet oil nozzle 12 of the plunger pump 3 through an inlet oil pipe 11. When the template sewing machine starts to work, the plunger pump 3 is started, so that the oil in the lower tank body 8 enters the plunger pump 3 through the inlet oil pipe 11. The plunger pump 3 is installed on the shuttle shaft 2 to lubricate the shuttle shaft 2. The redundant oil inside the plunger pump 3 flows back to the upper tank body 7 of the third oil sump 6 through the return oil pipe 9. The return oil pipe 9 is arranged in a two-stage structure, and an oil regulating valve 18 is arranged between the two sections of the return oil pipe 9. The oil regulating valve 18 can be used to adjust and control the amount of returned oil; the redundant oil on the surface of the shuttle shaft 2 enters the first oil sump 4.

[0024] A shuttle oil purification structure is respectively arranged between the upper layer bodies of the above-mentioned first oil sump 4 and the second oil sump 5, the second oil sump 5 and the third oil sump 6, and the upper layer body 7 of the third oil sump 6 and the lower layer body 8. The shuttle oil purification structure is selected from a filtering structure, an adsorption structure or a blocking structure. The shuttle oil entering the first oil sump 4 enters the lower layer body 8 of the third oil sump 6 after being purified by the purification structures between the upper layer bodies of the first oil sump 4 and the second oil sump 5, the second oil sump 5 and the third oil sump 6, and the upper layer body 7 of the third oil sump 6 and the lower layer body 8; the shuttle oil entering the upper layer body 7 of the third oil sump 6 enters the lower layer body 8 of the third oil sump 6 after being purified by the purification structure between the upper layer body 7 and the lower layer body 8 of the third oil sump 6.

[0025] Specifically, a filter plate 13 is arranged between the first oil sump 4 and the second oil sump 5. The shuttle oil in the first oil sump 4 enters the second oil sump 5 after filtering out large-particle impurities through the filter plate 13; a guiding inclined surface 16 is arranged at the bottom of the first oil sump 4, and the filter plate 13 is arranged at the lower position of the guiding inclined surface 16. Through the guiding inclined surface 16, the shuttle oil in the first oil sump 4 can be smoothly guided to the filter plate 13.

[0026] Specifically, a stepped oil filtering hole 14 is arranged between the second oil sump 5 and the upper layer body 7 of the third oil sump 6. The stepped oil filtering hole 14 is a blocking structure, including an oil passing hole communicating the second oil sump 5 and the third oil sump 6 and an annular step surrounding the edge of the oil passing hole. When the shuttle oil flows towards the oil passing hole, the heavier impurities in the shuttle oil will flow at the bottom. When contacting the annular step, the heavier impurities cannot cross the annular step and continue to flow, while the shuttle oil can cross the annular step without hindrance and continue to flow into the third oil sump 6 through the oil passing hole; in order to prevent the oil filtered out by the filter plate 13 from directly entering the oil passing hole without passing through the annular step, the filter plate 13 and the stepped oil filtering hole 14 are arranged in a staggered manner.

[0027] Specifically, a stepped oil filtering groove 15 is arranged between the upper layer body 7 and the lower layer body 8 of the third oil sump 6; the stepped oil filtering groove 15 is a blocking structure, which is arranged at the edge of the upper layer body 7 of the third oil sump 6 close to the lower layer body 8 and includes a strip-shaped step arranged along the edge; the stepped oil filtering hole 14 and the stepped oil filtering groove 15 are arranged in a staggered manner. The oil entering the upper layer body 7 of the third oil sump 6 from the return oil pipe 9 or the second oil sump 5 flows along the upper layer body 7. When contacting the strip-shaped step, the heavier impurities cannot cross the strip-shaped step and continue to flow, while the shuttle oil can cross the strip-shaped step without hindrance and continue to flow into the lower layer body 8.

[0028] In this embodiment, the specific structure of the third oil storage tank 6 is as follows: the lower layer tank body 8 of the third oil storage tank 6 is arranged in the middle of the upper layer tank body 7, that is, the upper layer tank body 7 and the lower layer tank body 8 of the third oil storage tank 6 form an inverted "convex" shape structure. Step oil filtering grooves 15 are respectively arranged at the connection positions on both sides of the upper layer tank body 7 and the lower layer tank body 8. The return oil pipe 9 is arranged on one side of the upper layer tank body 7, and step oil filtering holes 14 are arranged at the corresponding positions on the other side of the upper layer tank body 7. Preferably, the return oil pipe 9 is connected to the side of the upper layer tank body 7 of the third oil storage tank 6, and the inlet oil pipe 11 is connected to the bottom of the lower layer tank body 8 of the third oil storage tank 6.

[0029] To further enhance the purification effect, magnets 17 are respectively arranged on both sides of the upper layer tank body 7 of the third oil storage tank 6, and one of the magnets 17 is arranged at the corresponding position of the step oil filtering hole 14. Magnetic metal impurities such as iron filings can be adsorbed by the magnets 17.

[0030] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
