Description

Technical Field

[0001] The present application relates to the technical field of jacquard machines, and in particular to an automatic lubrication device for jacquard machines. Background Art

[0002] With the development of science and technology, textile machinery and equipment used in the textile industry have become more diversified and advanced. Jacquard machine is one of the textile equipment that is widely used in the textile industry.

[0003] Generally, for a jacquard machine, each lubrication point needs to be lubricated before each startup or during operation before it can work normally. When the jacquard machine is working, the lubricating oil loss of the chain used to drive the jacquard machine is high. Conventional manual lubrication requires stopping the operation of the jacquard machine for lubrication, which will reduce work efficiency. In addition, a large amount of lubricating oil will drip from the pores on the chain during manual lubrication, thereby causing a waste of lubricating oil. In addition, during manual lubrication, the sprocket needs to be manually rotated to move the chain, which is time-consuming and laborious. Therefore, those skilled in the art provide an automatic lubrication device for a jacquard machine to solve the problems raised in the above background technology. Utility Model Content

[0026] The following is combined with Figure 1-5 This application is described in further detail.

[0027] The present application discloses an automatic lubrication device for a jacquard machine, referring to Figure 1-5 , including a jacquard machine body 1 and a chain 2 and a sprocket 3 for driving the internal parts of the jacquard machine body 1, a lubricating mechanism for lubricating the chain 2 is installed on one side of the jacquard machine body 1, a movable groove 4 is opened in the middle of one side of the jacquard machine body 1, a driving mechanism for driving the lubricating mechanism to move is installed in the movable groove 4, and one side of the driving mechanism is fixedly connected to the lubricating mechanism; the lubricating mechanism includes an oil storage box 5, the bottom end of the oil storage box 5 is connected and installed with an oil outlet pipe 6, the oil outlet pipe 6 is installed with a self-locking component for controlling the oil outlet pipe 6 to output oil, a first connecting rod 7 is fixedly installed on the top of the self-locking component, a first spring 8 is sleeved on the first connecting rod 7, a limiting frame 9 is fixedly installed on the bottom end of the oil storage box 5, and the first connecting rod 7 is movably installed on the limiting frame 9; the driving mechanism includes a motor 10, the motor 10 is fixedly installed on the top of the jacquard machine body 1, the output shaft of the motor 10 is fixedly installed with a screw 11, and the screw 11 is threadedly installed with a driving block 12.

[0028] By adopting the above technical scheme, the utility model sets a self-locking component, which is convenient for lubrication. By utilizing the chain rod in the chain 2 and the chain hole between the chain rods, the chain rod pushes up the second connecting rod 23, thereby driving the self-locking component to move upward in the oil outlet pipe 6, and the elastic force of the second spring 16 can push the limit block 17 to move outward, so that a certain gap can be generated between the limit blocks 17, and the lubricating oil flows down from the gap to lubricate the chain rod, which can avoid the lubricating oil flowing down from the chain hole between the chain rods during manual lubrication, thereby causing waste of lubricating oil; and the oil storage box 5 can be driven to move upward by the driving mechanism, so that the second connecting rod 23 is disengaged from the chain hole, which can avoid unnecessary lubrication for a long time and waste of lubricating oil.

[0029] Reference Figure 1-5 The self-locking assembly includes a main shaft 13, a limit plate 14 is installed at the top and bottom ends of the main shaft 13, a plurality of telescopic rods 15 are fixedly installed in the middle of the main shaft 13, a second spring 16 is sleeved on the outer side of the plurality of telescopic rods 15, and a limit block 17 is fixedly installed at the other end of the plurality of telescopic rods 15.

[0030] By adopting the above technical solution, the multiple telescopic rods 15 can limit the moving angle of the limit block 17, thereby preventing the limit block 17 from moving up and down at different angles, so that when lubrication is not performed, gaps will be generated between the limit blocks 17, resulting in oil leakage.

[0031] Reference Figure 1-5 One end of the plurality of limit blocks 17 is arranged in an arc shape, and the cross-section of the plurality of limit blocks 17 is arranged in a circular shape.

[0032] By adopting the above technical solution and setting the cross-section of several limit blocks 17 to be circular, when the elastic force of the second spring 16 pushes the limit blocks 17 to move outward, a certain gap can be generated between the limit blocks 17, making it convenient for the lubricating oil to flow down from the gap and lubricate the chain rod.

[0033] Reference Figure 1-5 The oil outlet pipe 6 is arranged in a truncated cone shape which is wide at the top and narrow at the bottom, and the top end of the oil storage box 5 is connected to an oil inlet pipe 18 with a valve.

[0034] By adopting the above technical solution, the oil outlet pipe 6 is arranged in a truncated cone shape that is wide at the top and narrow at the bottom, so that when the self-locking component moves upward, oil can be discharged for lubrication, and when it moves downward, the oil outlet pipe 6 can be sealed.

[0035] Reference Figure 1-5 An oil collecting box 19 is fixedly installed at the bottom of the oil storage box 5 , and sleeve holes 22 are opened on both sides of the top of the oil collecting box 19 , and the sleeve holes 22 are sleeved in the middle of the chain 2 .

[0036] By adopting the above technical solution, the chain 2 can be conveniently installed in the sleeve hole 22 through the provided sleeve hole 22, so that the oil collecting box 19 can collect the dripping lubricating oil conveniently.

[0037] Reference Figure 1-5 A connecting pipe 20 is installed on one side of the bottom end of the oil collecting box 19, an oil pump 21 is installed on one end of the connecting pipe 20, the oil pump 21 is fixedly connected to one side of the oil collecting box 19, and another connecting pipe 20 is installed on the output end of the oil pump 21, and one end of the connecting pipe 20 is connected to the top of one side of the oil storage box 5.

[0038] By adopting the above technical solution, the lubricating oil collected in the oil collecting box 19 can be pumped into the oil storage box 5 through the oil pump 21 and the connecting pipe 20 through the connecting pipe 20, so that the dripping lubricating oil can be reused.

[0039] Reference Figure 1-5 A second connecting rod 23 is fixedly mounted on the bottom end of a limiting plate 14 , and the bottom end of the second connecting rod 23 is arranged in a chain hole on the chain 2 .

[0040] By adopting the above technical solution, when lubrication is convenient, the chain rod in the chain 2 and the chain hole between the chain rods are used, and the chain rod pushes up the second connecting rod 23, thereby driving the self-locking component to move upward in the oil outlet pipe 6 for oil lubrication.

[0041] Reference Figure 1-5 The diameter of the second connecting rod 23 is smaller than the diameter of the bottom end of the oil outlet pipe 6 .

[0042] By adopting the above technical solution, the diameter of the second connecting rod 23 is set smaller than the diameter of the bottom end of the oil outlet pipe 6, which can avoid the second connecting rod 23 and the bottom end of the oil outlet pipe 6 being set to the same diameter, thereby causing the second connecting rod 23 to block the bottom end of the oil outlet pipe 6.
