Description

Technical Field

[0001] This utility model belongs to the technical field of roller needle holders, and particularly relates to a micro-lubrication mechanism for roller needle holders. Background Technology

[0002] The roller needle holder is a key component in sewing machine parts used to fix the needle bar. It is commonly found in computerized flatbed sewing machines, high-speed sewing machines, and bar-tapping machines to ensure the stable operation of the needle bar during sewing. When using the needle holder, it needs to be lubricated, which requires the use of a micro-lubrication mechanism.

[0003] The following problems exist with the use of roller sewing machine needle holders on the market: When using traditional roller sewing machine needle holders, the needle bar moves in the upper and lower holes of the needle holder during high-speed sewing, generating friction. If lubrication is not provided in time, the needle holder holes, sliders and grooves, and needle bar will wear out faster, affecting the service life of the parts. Moreover, the industry has not yet adopted automatic lubrication, and employees still need to manually assist in lubrication, which is not convenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a micro-lubrication mechanism for roller needle holders to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A micro-lubrication mechanism for a roller needle holder includes a needle holder assembly, a needle holder assembly at the bottom of the needle holder assembly, an oil line on the side of the needle holder assembly, an oil supply pipe for the needle holder on the side of the oil line, an embedded oil sight glass assembly at the bottom of the oil supply pipe, a needle holder connector slider embedded inside the needle holder assembly, a needle holder connector assembly on the side of the needle holder connector slider, and oil-absorbing cotton on the side of the needle holder connector assembly.

[0006] Preferably, one end of the needle bar oil supply pipe is fixedly connected to an external thread pagoda connector, which is inserted inside the needle bar connector assembly.

[0007] Preferably, the embedded oil sight glass assembly has a rotary oil supply pipe on its side, and the rotary oil supply pipe is arc-shaped.

[0008] Preferably, the bottom of the pin connector assembly is provided with a pin assembly, and the pin assembly is strip-shaped.

[0009] Preferably, the oil-absorbing cotton is provided with oil-absorbing cotton clips on its side, and the number of oil-absorbing cotton clips is three.

[0010] Preferably, the oil-soaked cotton clip has screws embedded in its side, and the screws are symmetrically distributed.

[0011] This invention provides a micro-lubrication mechanism for a roller sewing machine needle holder, which has the following advantages: The mechanism adds a needle holder assembly at the bottom of the needle holder assembly, an oil line to the side of the needle holder assembly, a needle supply oil pipe to the side of the oil line, an embedded oil sight glass assembly at the bottom of the oil supply oil pipe, a needle connector slider embedded inside the needle holder assembly, a needle connector assembly to the side of the needle connector slider, and oil-absorbing cotton to the side of the needle connector assembly. When using this micro-lubrication mechanism, to prevent accelerated wear of parts, the lubricating oil in the embedded oil sight glass assembly is delivered to the oil line and absorbed by the needle connector slider of the needle holder assembly. When the needle connector slider moves, it generates negative pressure, causing the lubricating oil absorbed by the oil line to flow to the bottom of the needle holder assembly housing. The oil is then absorbed by the oil-absorbing cotton to lubricate the needle holder housing and the needle. This reliably ensures that the needle holder remains lubricated for a long time, unaffected by factors such as employees forgetting to add oil or not adding oil at all. Attached Figure Description

[0028] The working principle of the micro-lubrication mechanism for the roller needle holder is as follows: When using this micro-lubrication mechanism, in order to avoid accelerated wear of parts, the lubricating oil in the embedded oil sight assembly 5 is delivered to the oil line 2 and adsorbed onto the needle connector slider 7 of the needle holder assembly 1. When the needle connector slider 7 moves, it generates negative pressure, allowing the lubricating oil adsorbed by the oil line 2 to flow to the bottom of the needle holder assembly 1 housing. The oil-absorbing cotton 10 is fixed by the screw 12 and the oil-absorbing cotton clip 11, and then the oil under the needle holder housing is adsorbed onto the oil-absorbing cotton 10 for lubrication of the needle holder hole sleeve and the needle. The needle pierces the leather by moving the top thread up and down through the needle holder assembly 8, and then the top thread and bottom thread are completed by the rotary hook hooking the thread. By installing the rotary hook oil supply pipe 6 on the side of the embedded oil sight assembly 5, the rotary hook can be conveniently supplied with oil, reliably ensuring that the needle holder is kept in an oil-lubricated state for a long time, and will not be affected by factors such as employees forgetting to add oil or not adding oil.
