Description

An oiling module and an automatic sewing machine Technical Field

[0001] This utility model relates to sewing machine technology, and more particularly to an oiler module and an automatic sewing machine. Background Technology

[0002] With the development of technology, sewing machines are sewing faster and faster, which increases the friction between the sewing thread and the needle, causing the sewing thread to wear and break frequently due to the friction of the needle.

[0003] To solve this technical problem, some sewing machines have an oiler installed on the machine head housing. This oiler is used to soak the sewing thread in lubricating oil to increase the smoothness of the sewing thread, reduce the friction between the sewing thread and the needle, and prevent the sewing thread from wearing out and breaking.

[0004] However, lubricating oil penetrates into the sewing thread using penetrating force. Since the thickness and material of sewing threads vary, their penetrating force also varies. Existing oilers cannot be adjusted for sewing threads with different penetrating forces, resulting in some sewing threads with poor penetrating force not being able to fully absorb the lubricating oil, resulting in poor lubrication. On the other hand, some sewing threads with good penetrating force absorb too much lubricating oil, causing unnecessary waste. Summary of the Invention

[0005] To address the shortcomings of the prior art, this invention provides an oiler module and an automatic sewing machine that can be adjusted according to sewing threads with different penetration capabilities to ensure the lubrication effect of the sewing thread.

[0006] The technical problem to be solved by this utility model is achieved through the following technical solution:

The cotton seat connecting part is connected to the cotton seat mounting part and extends along the second direction. The oil-soaked cotton installation part is connected to the end of the cotton seat connecting part away from the cotton seat mounting part and close to the oil pressure plate, so as to be opposite to the pressure plate pressing part.

[0016] Furthermore, the mounting base is also provided with a first thread guide plate and a second thread guide plate, which are respectively arranged on both sides of the at least one oiler assembly along the direction of the sewing thread; the first thread guide plate has at least one first thread guide hole, one first thread guide hole corresponds to one oiler assembly, and each first thread guide hole is aligned with the oil-absorbing cotton of the corresponding oiler assembly; the second thread guide plate has at least one second thread guide hole, one second thread guide hole corresponds to one oiler assembly, and each second thread guide hole is aligned with the oil-absorbing cotton of the corresponding oiler assembly.

When the driving force of the driver is different, the pressing force of the oil-passing pressure plate on the oil-absorbing cotton is also different. The oil-absorbing cotton can release different amounts of lubricant under different pressing forces, thereby adjusting the oil-passing capacity of the oiler assembly. Therefore, the driving force of the driver can be adjusted according to the penetration power of the sewing thread to ensure that sewing threads with different penetration powers can obtain good lubrication effects.

[0027] Example 1

[0028] As shown in Figure 1, an oiler module includes:

[0029] The mounting base 31 has a mounting bottom surface and a mounting surface that are disposed opposite to each other along the first direction x;

[0030] At least one oiler assembly 32 is disposed on the mounting surface of the mounting base 31; each oiler assembly 32 includes an oil absorbent seat 311, an oil absorbent 312, an oil pressure plate 313, and a driver 314, wherein the oil absorbent seat 311 and the oil pressure plate 313 are disposed opposite each other, and the oil absorbent 312 is disposed on the side of the oil absorbent seat 311 facing the oil pressure plate 313; the driver 314 is connected to one of the oil absorbent seat 311 and the oil pressure plate 313 to drive one of the oil absorbent seat 311 and the oil pressure plate 313 to move relative to the other.

[0031] The oiler module of this utility model is fixedly installed on the surface of the sewing machine head housing via the mounting base 31. The sewing thread passes between the oil-absorbing cotton 312 and the oil-passing pressure plate 313. The oil-absorbing cotton 312 provides lubricant to the sewing thread, and the driver 314 drives the oil-absorbing cotton seat 311 and the oil-passing pressure plate 313 to move relative to each other, so that the oil-passing pressure plate 313 presses against the oil-absorbing cotton 312 located in the oil-absorbing cotton seat 311. When the driving force of the driver 314 is different, the pressing force of the oil-passing pressure plate 313 on the oil-absorbing cotton 312 is also different. Under different pressing forces, the oil-absorbing cotton 312 can release different amounts of lubricant, thereby adjusting the oil-passing capacity of the oiler assembly 32. Therefore, the driving force of the driver 314 can be adjusted according to the penetration power of the sewing thread to ensure that sewing threads with different penetration powers can obtain good lubrication effects.

The oil-absorbing cotton installation part 311c is provided with an oil-absorbing cotton groove 311d, and the oil-absorbing cotton 312 is disposed in the oil-absorbing cotton groove 311d. The thickness of the oil-absorbing cotton 312 is greater than the depth of the oil-absorbing cotton groove 311d.

[0038] Preferably, the oil-absorbing cotton device 311c is further provided with an oiling hole 311e that communicates with the oil-absorbing cotton groove 311d, for adding lubricating oil to the oil-absorbing cotton 312 in the oil-absorbing cotton groove 311d.

[0039] Preferably, the bottom of the oil-cotton groove 311d is provided with an oil storage groove 311f that communicates with the oil filling hole 311e for storing the added lubricating oil.

Each wire guide post 35 corresponds to one oiler assembly 32, and each wire guide post 35 is located next to the oil absorbent cotton 312 of the corresponding oiler assembly 32.

[0042] Each sewing thread passes through the corresponding first thread guide hole 331 and enters the oiler module. Then, guided by the corresponding thread guide post 35, it enters the corresponding oiler assembly 32, where the oiling pressure plate 313 presses it against the oil-absorbing cotton 312 to absorb the lubricating oil released from the oil-absorbing cotton 312.
