Description

Technical Field

[0001] This utility model relates to the field of knitting machinery technology, and in particular to a self-lubricating structure for the guide rail of a flat knitting machine head. Background Technology

[0002] In the modern textile industry, the flat knitting machine, with its efficient and flexible knitting characteristics, has become one of the core pieces of equipment in garment and fabric production. As the market's demands for higher quality, greater output, and greater diversity of knitted products continue to increase, flat knitting machines are developing towards higher speeds, greater precision, and greater intelligence. As a key moving component of the flat knitting machine, the reciprocating motion accuracy of the knitting head on the guide rail directly affects the knitting quality of the fabric and the operational stability of the equipment. The lubrication condition of the guide rail is a crucial factor determining the knitting head's motion performance. Most flat knitting machine guide rails are lubricated manually and periodically.

[0003] Since manual application is not only cumbersome and increases labor costs, but also has unstable lubrication effects, it is easy to have insufficient or excessive lubrication. In view of the above reasons, this application proposes a self-lubricating structure for the guide rail of the knitting flat knitting machine head. Utility Model Content

[0037] Example

[0038] like Figure 1-5 As shown, the present invention proposes a self-lubricating structure for the knitting flat knitting machine head guide rail, including a base 1, a needle bed 2 on the top of the base 1, two guide rail bodies 5 on the top of the needle bed 2, multiple oil outlet holes 6 and an internal thread hole on the top of the guide rail body 5, a sealing cover 7 in the internal thread hole, an oil injection hole at the bottom of the internal thread hole, the oil injection hole and the internal thread hole are connected, the sealing cover 7 and the internal thread groove are movably connected, a sealing plug at the bottom of the sealing cover 7 is adapted to the oil injection hole, an oil storage chamber for installing components and storing lubricating oil is provided in the oil storage chamber, an oil spraying structure 9 for spraying oil for lubrication is provided in the oil storage chamber, an alarm 3 and a PLC 4 are fixedly installed on the front of the base 1, a liquid level sensor 8 for detecting the level of lubricating oil is provided in the oil storage chamber, the liquid level sensor 8 can detect the level of lubricating oil in the oil storage chamber and send the data to the PLC 4, when the liquid level is lower than the set value, the PLC 4 will activate the alarm 3 to sound an alarm, reminding the operator that the liquid level is too low and needs to be added in time;

[0039] The oil injection structure 9 includes an oil pump 902 for pumping oil. An mounting plate 901 is fixedly installed at the bottom of the oil pump 902. The mounting plate 901 is fixedly connected to the inner wall of the oil storage chamber. A suction pipe 903 is provided on one side of the oil pump 902. The suction pipe 903 is used to draw lubricating oil from the oil storage chamber. A four-way pipe 904 is provided at the oil discharge end of the oil pump 902. Each of the multiple oil outlet branches of the four-way pipe 904 is provided with a hose 905 for guiding oil. An oil outlet 907 is provided at the other end of the hose 905. The oil outlet 907 is fixedly connected to the oil outlet hole 6. A one-way valve 906 is provided at the bottom of the oil outlet 907. The one-way valve 906 can prevent the backflow of the oil participating in lubrication and avoid the problem of oil contamination in the oil storage chamber. The hose 905 and the oil inlet end of the one-way valve 906 are fixedly connected.

[0040] Both sides of the guide rail body 5 are provided with oil absorption structures 10. The oil absorption structure 10 includes a mounting base 101. One side of the mounting base 101 is provided with a retaining strip 103 and a retaining groove 102. The cooperation between the retaining groove 102 and the retaining strip 103 enables the quick disassembly and assembly of the oil baffle 104, which facilitates the subsequent cleaning of the oil baffle 104. The retaining strip 103 and the retaining groove 102 are movably connected. One side of the retaining strip 103 is fixedly provided with an oil baffle 104. The side of the oil baffle 104 near the mounting base 101 is provided with an oil-absorbing cotton layer. The oil baffle 104 is used to receive lubricating oil overflowing from both sides of the guide rail body 5, and the oil-absorbing cotton layer is used to absorb the overflowing lubricating oil to prevent lubricating oil from dripping and contaminating the fabric.

[0041] In this embodiment, the level sensor 8 is used to detect the liquid level in the oil storage chamber. Before use, the working time of the oil pump 902 and the duration of each operation can be set via PLC4 to achieve automatic lubrication and control the amount of oil injected. When the lubrication time is reached, PLC4 starts the oil pump 902. The suction pipe 903 on one side of the oil pump 902 draws in the lubricating fluid from the oil storage chamber and delivers it to multiple hoses 905 through the four-way pipe 904. The oil in the hoses 905 passes through the one-way valve 906 and flows out from the oil outlet 907, acting on the surface of the guide rail body 5 to provide lubrication. When the machine head moves on the guide rail body 5, it will squeeze out some of the oil. The oil passes through the guide rail body 5. The oil flows downwards at an angle, and the oil baffle 104 can receive the overflowing oil. The oil-absorbing cotton layer will absorb the oil, preventing lubricating oil from dripping and contaminating the fabric. When the oil baffle 104 needs to be removed for cleaning, hold the oil baffle 104 and pull it to one side. The oil baffle 104 will drive the retaining strip 103, which will move in the retaining groove 102. When the retaining strip 103 is completely disengaged from the retaining groove 102, the oil baffle 104 can be removed. When cleaning is completed and it is installed, insert the retaining strip 103 into the retaining groove 102 to install the oil baffle 104. When the oil level in the oil storage chamber is lower than the set value, the PLC4 will activate the alarm 3 to sound an alarm, reminding the operator that the liquid level is too low and needs to be added in time.

[0042] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
