Description

Technical Field

[0001] The invention relates to the technical field of lubrication, in particular to an adjustable pressure device for grease injection lubrication of a jacquard machine bearing. Background Art

[0002] In the field of textiles, fabrics are usually woven with warp and weft. On the loom, the warp must be divided into two layers, upper and lower, and changed alternately according to a certain rule to form a channel for the weft to pass through, that is, the opening. After the weft is introduced into the opening, the two layers of warp alternate up and down according to the fabric organization method to form a new opening. Repeating this process completes the weaving of the fabric. The warp opening is completed by the warp opening selection structure, which is the most core step in textile technology. The warp opening selection structure must adapt to the needs of modern textile variety and long-term high-speed production, and should have the characteristics of simple structure, reliable performance, easy adjustment and unified management. At the same time, it is necessary to meet the requirements of clear opening, "scissor-shaped" opening, small friction and tension of the warp, etc., which puts higher requirements on the transmission structure of the jacquard machine;

[0003] For example, the invention patent with patent application number 201110164298.6 discloses an electronic jacquard machine knife lifting transmission mechanism, including a knife lifting mechanism at the lower end of the frame, several needle lifting arms on both sides of the frame for lifting the knife, several connecting rods connecting the needle lifting arms, and a transmission main shaft installed by fixed plates on both sides of the upper end of the frame; a driving sprocket is installed on the inner side of the fixed plate on the transmission main shaft, and a driving gear is installed on the outer side of the fixed plate; the driving sprocket is connected to an eccentric driven sprocket through a chain, and an eccentric gear is meshed on the driving gear.

[0004] The above patent realizes stable and efficient power transmission through the bearing transmission shaft structure, but the bearings need to be lubricated and maintained after long-term use to reduce internal friction and wear of the bearings, extend the fatigue life of the bearings, and ensure stable transmission. However, when adding lubricating grease, taking the above-mentioned jacquard machine transmission structure as an example, the bearing support transmission structure is compact, and the space reserved for bearing lubrication and maintenance is small, resulting in inconvenient operation and slow speed during the lubricating grease addition process. Due to the limitation of operating space, it is impossible to effectively use foreign objects to seal the bearings during the lubricating grease addition process. When the rotating shaft rotates the inner ring of the bearing to evenly apply the lubricating grease to various positions inside the bearing, the lubricating grease splashes with the rotation of the inner ring of the bearing, causing equipment pollution, and manual cleaning of the lubricating grease sticking to the equipment is required.

[0037] Specifically, such as Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, a bearing lubrication structure 6 is installed on the fixed plate 1 to automatically lubricate the two ball bearings 7 on the fixed plate 1; two sealing components in the bearing lubrication structure 6 are respectively arranged on both sides of the fixed plate 1, and each sealing component includes two heat-conducting outer rings 610, two heat-conducting inner rings 611 and two rubber sleeves 621. Two bearing mounting grooves 8 are provided on the outer side of the fixed plate 1, and the ball bearings 7 correspond to the bearing mounting grooves 8 one by one.

The outer shell of the telescopic rod three 636 is fixedly connected to one of the connecting plates two 620, and the piston end of the telescopic rod three 636 is fixedly connected to the other end connecting plate two 620. The dual-axis pneumatic cylinder 635 and the two telescopic rods three 636 are all penetrated through the fixed plate 1.

[0038] Specifically, such as Figure 1 、 Figure 5 、 Figure 6 、 Figure 9 、 Figure 10 and Figure 12As shown, an injection tube 69 and a guide pipe 4 625 are inserted on the two heat-conducting outer rings 610 in a sealing assembly provided on one side of the fixed plate 1. A telescopic guide assembly is provided between one side of the two injection tubes 69 and the glass box 61.

One end of the guide pipe 1 68 is connected to the adjacent injection tube. 69 is fixedly connected with a telescopic tube three 641, and a connecting frame 640 is fixedly sleeved on the outside of the telescopic tube three 641. The piston end of the pneumatic cylinder three 638 fixedly connected to the outside of the guide pipe one 68 is fixedly connected to the connecting frame 640. Since the telescopic tube three 641 can be extended and retracted back and forth, the operation of the pneumatic cylinder three 638 can be controlled to control the position of the injection tube 69 and the relative position between the injection tube 69 and the heat-conducting outer ring 610, thereby ensuring that the injection tube 69 and the heat-conducting outer ring 610 cooperate stably and efficiently.

[0039] A diversion pipe 2 623 is fixedly connected to the water inlet end of the water pump 622, and the diversion pipe 2 623 is used to connect to the water supply system. A diversion pipe 3 624 is fixedly connected to the water outlet end of the water pump 622. Both ends of the diversion pipe 3 624 are respectively fixedly connected to the normally closed ends of the two three-way valves 67. After the normally closed ends of the three-way valves 67 are controlled to open, water can be poured into the two diversion pipes 1 68.

[0040] A piston 63 is slidably inserted into the glass box 61. The top end of the piston 63 is arranged on the outside of the glass box 61 and is fixedly connected to a connecting plate 64. A telescopic rod 65 and a pneumatic cylinder 66 are fixedly inserted into the fixed plate 1. The piston ends of the telescopic rod 65 and the pneumatic cylinder 66 are fixedly connected to the connecting plate 64. Under the action of the pneumatic cylinder 66 and the telescopic rod 65, the connecting plate 64 can move up and down. A solenoid valve 62 is fixedly connected to the top of one side of the glass box 61. When the solenoid valve 62 is controlled to open, lubricating grease can be added to the interior of the glass box 61.

[0041] Specifically, such as Figure 9 、 Figure 10 and Figure 11As shown, the pressure plate 612 and the elastic gas storage member 613 are both arranged inside the heat-conducting outer ring 610, the pressure plate 612 is fixedly connected to the injection tube 69 and the two move synchronously, the elastic gas storage member 613 is fixedly connected to the heat-conducting outer ring 610, and guide holes 614 are opened on the pressure plate 612 and the elastic gas storage member 613.

Function, an air guide elbow 616 is fixedly connected between one side of the elastic air storage part 613 and the air inlet end of the pneumatic telescopic rod 617, the piston end of the telescopic rod 2 618 arranged on one side of the pneumatic telescopic rod 617 is fixedly connected to the sealing plate 619, and the outer shells of the pneumatic telescopic rod 617 and the telescopic rod 2 618 are fixedly connected to the inner wall of the heat-conducting outer ring 610, and when the pneumatic telescopic rod 617 and the telescopic rod 2 618 move to the left, the sealing plate 619 can move up and down inside the heat-conducting outer ring 610.

[0042] Specifically, such as Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 13 As shown, the guide pipe 4 625 is fixedly installed on the outer bottom of the heat-conducting outer ring 610 and is connected to the bottom of the inner cavity of the heat-conducting outer ring 610. The bottom end of the guide pipe 4 625 is fixedly connected to the telescopic pipe 1 626. The bottom end of the telescopic pipe 1 626 is fixedly connected to the one-way valve 627. The guide pipe 5 628 is fixedly connected between the two one-way valves 627. The telescopic pipe 1 626 can be retracted to meet the up and down movement needs of the guide pipe 5 628. Under the one-way conduction characteristics of the one-way valve 627, the liquid inside the guide pipe 5 628 cannot flow into the telescopic pipe 1 626. The bottom end of the fifth 628 is fixedly connected to the second telescopic tube 629, and the bottom end of the second telescopic tube 629 is fixedly connected to the sewage pump 630.

The shell of the second pneumatic cylinder 637 arranged inside the square groove 639 is fixedly connected to the fixed plate 1. Because the second telescopic tube 629 can be extended and retracted up and down, the piston end of the second pneumatic cylinder 637 is fixedly connected to the diversion pipe five 628. By controlling the operation of the second pneumatic cylinder 637, the diversion pipe five 628 can be controlled to move up and down.

[0043] Sealing sleeves 1 632 are provided at both ends of the outer side of the diversion pipe 5 628, and sealing sleeve 2 633 is provided on the top of the sealing sleeve 1 632. A plurality of drainage holes 631 are provided inside the sealing sleeve 2 633, all of which are opened on the outer side of the diversion pipe 5 628. The sealing sleeve 2 633 and the sealing sleeve 1 632 are both fixedly installed on the fixed plate 1. The two sealing sleeves 2 633 are respectively provided at the bottom of the two ball bearings 7 on the fixed plate 1 where the bearing lubrication structure 6 is located. A confluence groove 634 is provided at the bottom of the inner cavity of the bearing mounting groove 8. The confluence groove 634 is opened on the fixed plate 1 and is connected to the sealing sleeve 2 633, so that there is a waste discharge space at the bottom of the outer ring of the ball bearing 7.

[0044] Specifically, the jacquard machine and the bearing lubrication structure 6 are connected to a human-machine interaction device to control their automated work. For the purpose of public technical application, details will not be given here.

[0045] The bearing lubrication structure 6 is installed on the fixed plate 1 to perform grease lubrication maintenance on the two ball bearings 7 installed on the fixed plate 1. The specific working principle is as follows:

[0046] First, observe the glass box 61 made of transparent material to determine whether the glass box 61 has sufficient grease and lubricant. Then, control the pneumatic cylinder 1 66 to work and extend to push the connecting plate 1 64 and the piston 63 upward. When the piston 63 moves up to the limit, control the solenoid valve 62 to work and open, and then inject grease and lubricant into the interior of the glass box 61 through the solenoid valve 62, and finally close the solenoid valve 62.

[0047] Subsequently, the dual-axis pneumatic cylinder 635 is controlled to work and contract, and the dual-axis pneumatic cylinder 635 drives the two sealing components to approach each other. When the heat-conducting outer ring 610 partially enters the bearing mounting groove 8 and the heat-conducting inner ring 611 moves to the outside of the rubber jacket 621 on one side, the dual-axis pneumatic cylinder 635 stops working. At this time, the heat-conducting outer ring 610, the heat-conducting inner ring 611 and the rubber jacket 621 cooperate to seal the bearing mounting groove 8 at one end, and the heat-conducting inner ring 611 and the heat-conducting outer ring 610 are rotatably installed, and the rotation of the transmission shaft 1 2 and the transmission shaft 2 4 is not affected. Under the action of the two sealing components, both ends of the two bearing mounting grooves 8 are sealed, and the ball bearing 7 is sealed; during this process, the pneumatic cylinder three 638 works to push the injection tube 69 and the heat-conducting outer ring 610 to move synchronously, so that the injection tube 69 remains in a state of partially penetrating the heat-conducting outer ring 610.

[0048] Subsequently, the two three-way valves 67 in the bearing lubrication structure 6 are controlled to open their normally closed ends. At this time, the two three-way valves 67 are connected to the guide pipe 3 624, and the water pump 622 is controlled to work. The water pump 622 fills the guide pipe 1 68, the telescopic pipe 3 641 and the injection pipe 69 with water through the two three-way valves 67 in the guide pipe 3 624. After a period of time, the water pump 622 stops working, and the water flushes and cleans the residual grease and lubricating paste in the guide pipe 1 68, the telescopic pipe 3 641 and the injection pipe 69. The grease and lubricating paste and water enter the sealed bearing mounting groove 8. At this time, the transmission shaft 1 2 and the transmission shaft 2 4 are controlled. The low-speed rotation causes the rotating transmission shaft 1 2 and the inner ring of the ball bearing 7 fixed to the transmission shaft 2 4 to rotate, and the inner and outer rings of the ball bearing 7 move relative to each other, stirring the mixture of grease and water, so that the water containing a certain amount of grease cleans the inside of the ball bearing 7, ensuring lubrication protection between the inner and outer rings of the ball bearing 7 and the balls, while cleaning out impurities between the inner and outer rings of the ball bearing 7, ensuring efficient maintenance of the ball bearing 7 during operation, and utilizing the grease remaining in the guide pipe 1 68, the telescopic pipe 3 641, and the injection pipe 69, thereby reducing resource waste;

[0049] Then, the second pneumatic cylinder 637 is controlled to operate for a period of time, and the fifth diversion pipe 628 moves downward a distance, so that the fifth diversion pipe 628 moves downward and leaves the interior of the second sealing sleeve 633, and the drainage hole 631 moves out of the interior of the second sealing sleeve 633. At this time, the sewage in the bearing mounting groove 8 enters the interior of the fifth diversion pipe 628 through the confluence groove 634, the second sealing sleeve 633, and the drainage hole 631 and is stored. The grease used to lubricate the ball bearing 7 completes the protective cleaning of the ball bearing 7.

[0050] The second pneumatic cylinder 637 is controlled to push the diversion pipe 5 628 to reset, the three-way valve 67 is controlled to be normally open, and the first pneumatic cylinder 66 is controlled to operate at low power to drive the piston 63 to slowly move downward. The grease inside the glass box 61 is subjected to low pressure, and the grease slowly enters the interior of the diversion pipe 1 68. The three-way valve 67 and the first pneumatic cylinder 66 work for a period of time and then stop working. The protective cleaning work of the ball bearing 7 is performed again. After the ball bearing 7 is protectively cleaned 2 to 4 times, the preliminary maintenance work of the ball bearing 7 is completed.

[0051] Subsequently, the dual-axis pneumatic cylinder 635 is controlled to work and contract again, so that the heat-conducting outer ring 610 continues to move toward the inside of the bearing mounting groove 8. The pneumatic cylinder three 638 and the dual-axis pneumatic cylinder 635 work synchronously, and the relative position between the injection tube 69 and the heat-conducting outer ring 610 remains unchanged. Finally, the heat-conducting outer ring 610 presses against the outer ring of the ball bearing 7, and the heat-conducting inner ring 611 presses against the inner ring of the ball bearing 7. One end of the injection tube 69 is partially inserted between the inner and outer rings of the ball bearing 7. The two sealing components enter the material blocking state under the action of the dual-axis pneumatic cylinder 635. The remaining position between the inner rings of the ball bearing 7 is blocked by the heat-conducting outer ring 610 and the heat-conducting inner ring 611. The gap between the inner and outer rings of the ball bearing 7 is blocked and sealed. Subsequently, the pneumatic cylinder one 66 is controlled to work and push the piston 63 to move down a certain distance at a low speed, so that the inside of the injection tube 69 is filled with grease and lubricating paste, and then the pneumatic cylinder one 66 is controlled to work and push the piston 63 to move down at a low speed. The pneumatic cylinder 66 moves down quickly for a short distance, so that the grease lubricating paste inside the glass box 61 is subjected to high pressure in a short time, and the injection tube 69 sprays part of the grease lubricating paste between the inner and outer rings of the ball bearing 7. The inner ring of the ball bearing 7 rotates to break up the grease lubricating paste. The pneumatic cylinder 66 works multiple times, and the injection tube 69 sprays a certain amount of grease lubricating paste between the inner and outer rings of the ball bearing 7 multiple times, so that the inner and outer rings of the ball bearing 7 are evenly and efficiently lubricated and maintained. Under the action of the two sealing components, the grease lubricating paste will not splash as the inner ring of the ball bearing 7 rotates, which reduces the waste of grease lubricating paste and avoids contamination of textiles during the maintenance process of the ball bearing 7 using the grease lubricating paste. The lubrication and maintenance work of the ball bearing 7 can be completed when the jacquard machine is operating normally, reducing the cost investment in the maintenance of the ball bearing 7.

[0052] Finally, the sewage pump 630 is controlled to work to discharge the wastewater in the diversion pipe 5 628, and then the bearing lubrication structure 6 is controlled to work to restore the initial state.

[0053] In addition, the bearing lubrication structure 6 is controlled to work. After the two sealing components enter the material blocking state under the action of the dual-axis pneumatic cylinder 635, the pneumatic cylinder 3 638 is controlled to work and contract, so that the injection tube 69 moves in the direction away from the ball bearing 7. The heat-conducting outer ring 610 does not move at this time, so that the open end of the injection tube 69 enters the interior of the heat-conducting outer ring 610. During the relative movement between the injection tube 69 and the heat-conducting outer ring 610, the pressure plate 612 fixed to the injection tube 69 moves. When the injection tube 69 moves relative to the heat-conducting outer ring 610, the pressure plate 612 fixed to the injection tube 69 moves. After the open end of 69 enters the interior of the heat-conducting outer ring 610 for a distance, the pressure plate 612 moves to squeeze the elastic gas storage member 613, and the air pressure inside the elastic gas storage member 613 increases. The gas inside the elastic gas storage member 613 enters the interior of the pneumatic telescopic rod 617 through the air guide elbow 616. The pneumatic telescopic rod 617 extends and pushes the sealing plate 619 downward. After the pneumatic cylinder 3 638 stops working, the channel reserved on the heat-conducting outer ring 610 for the movement of the injection tube 69 is sealed by the sealing plate 619, so that The interior of the heat-conducting outer ring 610 is in a sealed state; then the normally closed end of the three-way valve 67 is controlled to open, and the water pump 622 is operated to inject water into the injection tube 69. The water is transported to the interior of the heat-conducting outer ring 610 by the injection tube 69. After flowing inside the heat-conducting outer ring 610, the water is discharged through the guide pipe 4 625 fixedly connected to the bottom of the heat-conducting outer ring 610. At this time, the heat-conducting outer ring 610 is in contact with the outer ring of the ball bearing 7, and the heat-conducting inner ring 611 is in contact with the inner ring of the ball bearing 7. The heat generated by the high-speed rotation of the inner ring of the ball bearing 7 is exchanged by the heat-conducting outer ring 610 and the heat-conducting inner ring 611, which has the effect of dissipating heat and cooling the ball bearing 7, so that the bearing lubrication structure 6 has the function of automatic, quantitative and rapid grease lubrication of the ball bearing 7. At the same time, when the ball bearing 7 works at high speed for a long time, by controlling the working state of the bearing lubrication structure 6, the bearing lubrication structure 6 uses the existing pipeline system to temporarily cool and dissipate heat to the ball bearing 7, thereby ensuring the service life of the ball bearing 7.

[0054] A telescopic tube 1 626 is fixedly connected to the bottom end of the diversion pipe 4 625, and a one-way valve 627 is fixedly connected between the telescopic tube 1 626 and the diversion pipe 5 628. The water after heat exchange with the inside of the heat-conducting outer ring 610 enters the inside of the diversion pipe 5 628 through the diversion pipe 4 625, the telescopic tube 1 626 and the one-way valve 627, and controls the sewage pump 630 to discharge the water.

[0055] Finally, the control pneumatic cylinder three 638 works to push the injection tube 69 toward the ball bearing 7. When the pressure on the elastic air storage part 613 is reduced, the internal air pressure of the pneumatic telescopic rod 617 decreases and contracts, and the sealing plate 619 moves up to meet the need for the open end of the injection tube 69 to leave the inside of the heat-conducting outer ring 610. After the relative position between the injection tube 69 and the heat-conducting outer ring 610 is restored to its original state, the bearing lubrication structure 6 returns to its initial state.
