Description

Technical Field

[0001] This utility model relates to the field of water jet loom technology, and in particular to an oil supply device for a water jet loom selvage assembly. Background Technology

[0002] Water jet looms use water as the weft insertion medium. The jetting water creates frictional traction on the weft yarn, pulling it into the shed where it interweaves with the warp yarn to form a fabric. During the operation of a water jet loom, the weft yarn is trimmed after each insertion, causing fraying on both sides of the fabric. This makes the warp yarns on the selvage prone to falling off. The selvage assembly's function is to wrap the weft yarn with selvage yarn after each insertion to prevent the warp yarns from falling off.

[0003] The applicant was granted a patent certificate on January 5, 2024, with publication number CN220303407U and invention title "A centralized oil supply device for a water jet loom selvedge assembly". The device includes a connecting plate detachably disposed on the rear side of the housing of the selvedge assembly, multiple oil supply nozzles mounted on the connecting plate, and multiple oil supply hoses, one end of which is connected to the multiple oil supply nozzles. The other ends of the multiple oil supply hoses are respectively connected to the joint positions or bearing positions of the selvedge assembly.

[0004] However, in actual use, because multiple oil supply nozzles are located on the rear side of the selvage assembly, the frame of the water jet loom will more or less interfere with the operation of adding lubricating grease, which makes adding lubricating grease somewhat inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide an oil supply device for the selvage assembly of a water jet loom, which facilitates the addition of lubricating grease.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an oil supply device for a water-jet loom selvedge assembly, comprising a connecting plate, multiple oil supply nozzles mounted on the connecting plate, and multiple oil supply hoses, one end of which is connected to the multiple oil supply nozzles. The other ends of the multiple oil supply hoses are respectively connected to various joint positions or bearing positions of the selvedge assembly. A movable connecting mechanism is provided at the upper end of one side of the connecting plate for mounting on the rear side of the selvedge assembly housing, allowing the connecting plate to rotate. A movable connecting mechanism is provided at the lower end of one side of the connecting plate, located below the movable connecting mechanism and passing through the connecting plate, for... The threaded connection is a fixed knob bolt on the rear side of the housing of the hinge assembly; the movable connection mechanism includes a connecting seat with a spherical hole larger than a semicircle, a plurality of connecting bolts passing through the connecting seat for threaded connection to the rear side of the housing of the hinge assembly, a spherical head movably disposed in the spherical hole of the connecting seat, a connecting rod disposed between the spherical head and the connecting plate, and a damping structure disposed between the connecting seat and the spherical head, which allows the connecting plate to be fixed by friction after rotation angle; when the fixing knob bolt is unlocked, the connecting plate can rotate around the center of the spherical head to drive the oil supply nozzle to face upward.

[0007] A further feature of this invention is that the connecting seat includes a base and a cover plate mounted on the base by fixing screws. After the base and cover plate are installed, they form the spherical hole. A plurality of connecting bolts are used to fix the upper and lower ends of the base to the rear side of the housing of the helical assembly. The connecting rod is threadedly connected to the connecting plate.

[0008] A further feature of this invention is that the damping structure includes a groove channel disposed on the surface of the spherical head and a rubber layer formed and disposed within the groove channel and protruding from the annular groove. After the spherical head is installed, the rubber layer is pressed between the spherical head and the inner wall of the spherical hole.

[0009] A further feature of this invention is that the groove channel includes two first annular grooves located in the upper and lower halves of the spherical head, and two second annular grooves located in the left and right halves of the spherical head.

[0010] A further feature of this invention is that the front side of the connecting seat is provided with a movable groove communicating with the top of the spherical hole, and when the connecting plate is rotated upward to a horizontal state, the connecting rod is located at the end of the movable groove.

[0011] In summary, the beneficial effects of this utility model are:
