Description

Technical Field

[0001] This utility model relates to the field of electronic jacquard machine guide rail lubrication technology, and in particular to an electronic jacquard machine guide rail lubrication device. Background Technology

[0002] As the core equipment for the textile industry to achieve complex pattern weaving, the electronic jacquard machine's guide rail assembly is a key structure to ensure the precise reciprocating motion of the moving parts.

[0003] The fitting precision between the guide rail and the sliding components directly determines the clarity of the woven pattern and the stability of the equipment operation. In order to reduce frictional loss between the guide rail and the sliding components and extend the service life of the equipment, it is essential to provide continuous and stable lubrication to the guide rail.

[0004] While existing electronic jacquard machine guide rail lubrication devices achieve lubrication of the guide rails, they lack an effective filtration mechanism. Excess lubricant, mixed with fiber impurities generated during weaving, easily accumulates in the grooves, exacerbating wear on the guide rails and sliding components, reducing equipment operating accuracy, and increasing maintenance frequency and costs. Furthermore, simple drip lubrication makes it difficult to achieve uniform lubricant coverage, especially in the multi-faceted contact areas of the guide rail grooves, where lubrication dead zones often exist, and excess lubricant cannot be effectively recovered. Therefore, an electronic jacquard machine guide rail lubrication device is proposed to solve the above problems. Utility Model Content

The lubrication cavity 3 has a U-shaped cavity structure, with one end of the electrically controlled metering valve 7 connected to the inner wall of the lubrication cavity 3 and the other end fixedly connected to the bottom of the lubricant storage tank 5. The U-shaped structure of the lubrication cavity 3 can form a wrapping lubrication for the lubricating balls 42. The connection method of the electrically controlled metering valve 7 ensures that the lubricant can be accurately delivered to the lubrication cavity 3. A lubrication assembly 4 is provided between the inner walls of the lubrication cavity 3 and the slide groove 2. The lubrication assembly 4 is located between the lubrication cavity 3 and the slide groove 2. The lubrication slot 41 provides space for the installation and sliding of the lubrication ball 42. The lubrication assembly 4 includes a lubrication slot 41, which is provided in multiple sets. Each set of lubrication slots 41 is opened along three sides of the inner wall of the slide groove 2, and the multiple sets of lubrication slots 41 are evenly distributed along the length of the slide groove 2. The three sets of lubrication slots 41 correspond to the three sides of the inner wall of the slide groove 2 respectively. The evenly distributed distribution can ensure the uniformity of lubrication. The lubrication ball 42 is slidably engaged inside the lubrication slot 41. There are multiple lubrication balls 42, and the multiple lubrication balls 42 are distributed along the length of the lubrication slot 41. The lubrication ball 42 slides in the lubrication slot 41, which can transfer the lubricant of the lubrication cavity 3 to the sliding parts in the slide groove 2 to achieve rolling lubrication.

[0031] Reference Figure 1 , Figure 3 and Figure 4A recycling filter assembly 6 is installed between the guide rail body 1 and the slide 2. The recycling filter assembly 6 includes a recycling tank 61 and a recycling pump 67. The recycling tank 61 is used to collect excess lubricant, and the recycling pump 67 realizes the return of lubricant. The recycling tank 61 is opened on the inner wall of the slide 2. There are two recycling tanks 61, which are mirror images of each other along the central axis of the slide 2. The two recycling tanks 61 are symmetrically distributed on the inner wall of the slide 2, which can fully collect the excess lubricant in the slide 2. The bottom of the recycling pump 67 is fixedly connected to the top of the guide rail body 1. A return pipe 68 is fixedly connected between the output end of the recycling pump 67 and the inner wall of the lubrication chamber 3. The recycling pump 67 sends the filtered lubricant back to the lubrication chamber 3 through the return pipe 68 to realize recycling. A suction pipe 66 is fixedly connected to the input end of the recycling pump 67. A suction pipe 66 is fixedly sleeved on the outside of the suction pipe 66. The sealing cap 64 and the suction pipe 66 are connected to the recovery pump 67. The sealing cap 64 serves to seal and install the filter cylinder 65 and the filter 63. The bottom end of the sealing cap 64 is fixedly connected to the filter cylinder 65. The bottom end of the suction pipe 66 extends to the bottom of the filter cylinder 65. The filter cylinder 65 can filter large particulate impurities in the lubricant. The suction pipe 66 extends into its interior to ensure sufficient liquid absorption. The bottom end of the sealing cap 64 is equipped with the filter 63. The outer wall of the sealing cap 64 and the inner wall of the filter 63 are connected by a threaded structure. The filter 63 is connected to the sealing cap 64 by threads, which is convenient for disassembly and replacement. It can further filter the lubricant. The bottom of the filter 63 is connected to the inner wall of the recovery tank 61 by a recovery pipe 62. The recovery pipe 62 transports the lubricant in the recovery tank 61 to the filter 63, completing the first step of the recovery process.

[0032] Working principle: First, the lubricant storage tank 5 stores the lubricating medium. After the release amount is controlled by the electronic metering valve 7, the lubricant is delivered to the lubrication chamber 3, which has a U-shaped cavity structure. Then, the lubricant in the lubrication chamber 3 is transferred through the lubrication balls 42 of the lubrication assembly 4 between the slide groove 2 and the lubrication chamber 3. Multiple lubrication balls 42 slide along multiple sets of three-sided lubrication grooves 41 with equal spacing, transferring the lubricant to the sliding parts in the slide groove 2 to achieve rolling lubrication. At the same time, the excess lubricant in the slide groove 2 is collected by two recovery tanks 61 symmetrically arranged along the central axis, and transported to the filter screen cylinder 65 of the filter 63 through the recovery pipe 62 for filtration. After fine filtration, the filtered lubricant is returned to the lubrication chamber 3 by the recovery pump 67 through the return pipe 68, completing the recycling of the lubricant.
