Description

Technical Field

[0001] The utility model relates to the technical field of warp knitting machines, in particular to an oiling tooling for a comb of a warp knitting machine. Background Art

[0002] In the existing warp knitting machine, the guide yarn needle is driven to complete the yarn laying in front of the needle and forming loops and the crosswise movement of the guide yarn needle in front of and behind the needle through the swing between needles and the crosswise movement in front of and behind the needle, so as to form a warp knitted fabric and endow the change of the tissue structure; the swing between needles of the comb is realized by driving the comb guide seat through a rocker; the upper and lower constant velocity joints are fixedly installed on the comb guide seat; corresponding to the comb guide seat, comb brackets are arranged in the length direction of the comb, and inserting rods corresponding to the upper and lower constant velocity joints are arranged on the brackets. The inserting rods move freely and horizontally in the constant velocity joint with a linear ball bearing, and under the action of the comb crosswise movement mechanism, the comb completes a stable crosswise movement according to the pattern requirements.

[0003] When the warp beam yarn corresponding to each comb runs out, the comb is taken down from the comb guide seat, the yarn is re-wound on the shaft, and after the yarn is wound, a little butter is manually applied at the upper and lower constant velocity joints according to the operation requirements to prevent dry friction between the inserting rod and the constant velocity joint of the high-speed running machine, which may cause serious wear and affect the running accuracy of the machine. Then the comb is installed and the machine is restarted for production. When manually applying butter at the upper and lower constant velocity joints, the phenomenon of uneven oil application or even missed oil application may occur, resulting in dry friction between the inserting rod and the constant velocity joint, accelerating the wear between components. When applying oil on the inserting rod, since there are oil seals at both ends of the linear ball bearing of the constant velocity joint, the butter is blocked outside and cannot enter the worn parts of the inserting rod and the linear ball bearing beads, so it cannot play a lubricating role at all. To solve the problems of inconvenient oiling, uneven oiling and easy oil stain on the fabric surface, this utility model provides an oiling tooling for a comb of a warp knitting machine. Content of the Utility Model

[0004] The utility model discloses an oiling tooling for a comb of a warp knitting machine, which mainly solves the problem that it is inconvenient to apply oil to the linear ball bearing in the constant velocity joint of the comb guide seat of the existing warp knitting machine.

Along the axial direction of the oil injection part, multiple groups of oil injection hole groups for injecting oil into the linear bearing are arranged through the oil injection part. Each group of oil injection hole groups is arranged by a plurality of oil injection holes arranged in a straight line, and the oil injection holes are communicated with the oil injection channel.

[0035] See Figure 1 and Figure 2 , an oiling tooling for a warp knitting machine comb includes a connecting part 1 and an oil injection part 2. The connecting part 1 and the oil injection part 2 are integrally formed. The connecting part 1 is connected to the output end of a grease gun. An oil injection channel 21 communicating with the output end of the grease gun is provided in the oil injection part 2. Along the axial direction of the oil injection part 2, multiple groups of oil injection hole groups for injecting oil into linear bearings penetrate through the oil injection part 2. The multiple groups of oil injection hole groups are arranged by a plurality of oil injection holes 22 arranged in a straight line. The oil injection holes 22 communicate with the oil injection channel 21.

[0036] With the above structure, when it is necessary to lubricate the linear bearing, since the connecting part 1 and the lubricating part 2 are provided on the lubricating tooling, therefore, after connecting the connecting part 1 to the output end of the grease gun, under the action of the output end of the grease gun being communicated with the lubricating channel 21, the lubricating part 2 is inserted into the linear bearing, and then the grease gun injects grease into the lubricating channel 21, so that the grease flows along the lubricating channel 21 and then is injected into the linear bearing through the lubricating holes 22, thus preventing both hands from contaminating the grease. And with the arrangement of multiple lubricating holes 22, it is convenient to lubricate, avoiding problems such as missed lubrication and uneven lubrication, reducing the dry friction and wear between the insertion rod and the ball cage, improving the operating efficiency of the warp knitting machine, and being able to save the amount of grease used, reducing the waste cloth inevitably generated due to grease contamination, and reducing the unit cost of fabric production.

[0037] In one embodiment, referring to Figure 1 and Figure 2 , multiple groups of lubricating hole groups are matched with the number of rows of balls in the linear bearing. In actual use, with multiple groups of lubricating hole groups being matched with the number of rows of balls in the linear bearing, the injected grease can be smeared on the balls faster, thus shortening the lubricating time and improving the lubricating effect.

[0038] A connecting channel 11 is provided in the connecting part 1, and the lubricating channel 21 is communicated with the grease gun through the connecting channel 11. In actual use, through the setting of the connecting channel 11, the connecting channel 11 of the connecting part 1 can be directly connected to the output end of the grease gun, and when the grease gun is lubricating, the grease is injected into the lubricating channel 21 through the connecting channel 11.

[0039] A threaded hole 12 for threaded connection with the output end of the grease gun is provided in the connecting channel 11. In actual use, the output end of the grease gun can be a hollow hose with an external threaded connection end. By connecting the external thread of the hollow hose through the threaded hole 12, the connecting part 1 can be stably installed on the output end of the grease gun to achieve seamless docking of the lubricating tooling and the grease gun, avoiding the contamination of grease by both hands during lubrication.

[0040] In one embodiment, referring to Figure 1 and Figure 2 , the end of the lubricating part 2 away from the connecting part 1 has an arc surface structure 23. In actual use, by providing an arc surface structure 23 at the end of the lubricating part 2, when the lubricating part 2 is inserted into the linear bearing, the arc surface structure 23 can play a guiding role in the end of the lubricating part 2, making it easier to insert into the linear bearing.

[0041] A frustum structure is provided at the connection end of the connecting part 1 and the oil injection part 2. The end with the larger diameter of the frustum structure is connected to the connecting part 1, and the end with the smaller diameter is connected to the oil injection part 2. In actual use, under the frustum structure provided at the connection end of the connecting part 1 and the oil injection part 2, after the oil injection part 2 is completely inserted into the linear bearing, it can continue to be pushed towards the linear bearing, so that the frustum structure abuts against the linear bearing, facilitating the close fit of this part with the linear bearing, avoiding the leakage of grease from this part during oil injection, and thus preventing the hands from being contaminated by the grease.
