Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of lubrication, and particularly to an adjustable pressure device for grease lubrication of a jacquard machine bearing. Background Art
[0002] In the textile field, fabrics are usually woven from warp and weft threads. On a loom, the warp threads must be divided into two upper and lower layers and alternately changed according to a certain rule to form a passage for the weft thread to pass through, that is, an opening. After the weft thread is introduced into the opening, the two layers of warp threads alternate up and down according to the fabric weaving method to form a new opening. Repeating this process completes the weaving of the fabric. The warp thread opening is completed by a warp thread opening selection structure, which is the most core step in textile technology. The warp thread opening selection structure must adapt to the needs of modern textile variety diversification and long-term high-speed production, and should have the characteristics of simple structure, reliable performance, convenient adjustment, and unified management. At the same time, it is required to achieve clear openings, the formation of a "scissor shape" for the openings, and small warp thread friction and tension. This poses higher requirements for the transmission structure of the jacquard machine. For example, the invention patent with the patent application number 201110164298.6 discloses a lifting knife transmission mechanism for an electronic jacquard machine, which includes a lifting knife at the lower end of the machine frame, a number of lifting needle arms for lifting the lifting knife on both sides of the machine frame, a number of connecting rods connecting the lifting needle arms, and a transmission main shaft installed by fixing plates on both sides at the upper end of the machine frame; on the transmission main shaft, a driving sprocket is installed inside the fixing plate, and a driving gear is installed outside the fixing plate; the driving sprocket is connected with an eccentric driven sprocket through a chain, and an eccentric gear is engaged with the driving gear.
[0003] The above patent realizes stable and efficient power transmission through a bearing transmission shaft structure. However, after long-term application of the bearing, lubrication and maintenance are required to reduce internal friction and wear of the bearing, extend the fatigue life of the bearing, 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 lubrication and maintenance of the bearing is small, resulting in inconvenient operation and slow speed during the process of adding lubricating grease. Under the limitation of the operation space, external objects cannot be effectively used to seal the bearing during the process of adding lubricating grease. When the inner ring of the bearing rotates by the rotating shaft part to evenly apply the lubricating grease to various positions inside the bearing, the lubricating grease splashes along with the rotation of the inner ring of the bearing, causing equipment pollution, and it is necessary for manual cleaning of the lubricating grease adhered to the equipment.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1.

The inner ring of the ball bearing rotates to disperse the grease lubricant. The pneumatic cylinder 1 works multiple times, and the injection pipe sprays a certain amount of grease lubricant between the inner and outer rings of the ball bearing multiple times, so that the area between the inner and outer rings of the ball bearing is lubricated and maintained evenly and efficiently. Under the action of the two sealing components, the grease lubricant will not splash as the inner ring of the ball bearing rotates. While reducing the waste of the grease lubricant, it also avoids polluting the equipment and textiles during the maintenance of the ball bearing with the grease lubricant. The lubrication and maintenance of the ball bearing can be completed under the normal operation of the jacquard machine, reducing the cost investment in the maintenance of the ball bearing.
[0016] 2. When the present application is in use, the water pump is controlled to work. The water pump fills the inside of the diversion pipe 1, the telescopic pipe 3 and the injection pipe with water through two three-way valves in the diversion pipe 3. After a period of time, the water pump pauses working. After the water flushes and cleans the residual grease lubricant inside the diversion pipe 1, the telescopic pipe 3 and the injection pipe, the grease lubricant and the water enter the sealed bearing installation groove. At this time, the drive shaft 1 and the drive shaft 2 are controlled to rotate at a low speed. The inner ring of the ball bearing fixed by the rotating drive shaft 1 and the drive shaft 2 rotates, and there is relative movement between the inner and outer rings of the ball bearing. The mixture of the grease lubricant and the water is stirred, so that the water containing a certain amount of grease lubricant cleans the inside of the ball bearing. While ensuring the lubrication and protection between the inner and outer rings of the ball bearing and the balls, the impurities between the inner and outer rings of the ball bearing are cleaned out, ensuring the high efficiency of the maintenance during the operation of the ball bearing, and making use of the residual grease lubricant inside the diversion pipe 1, the telescopic pipe 3 and the injection pipe, reducing the waste of resources.

[0020] Embodiment: As Figures 1 - 13As shown in the figure, the present invention provides a technical solution for an adjustable pressure device for grease lubrication of a jacquard machine bearing, including two fixing plates 1. A first transmission shaft 2 and a second transmission shaft 4 are arranged between the two fixing plates 1. Ball bearings 7 are fixedly connected between the outer sides of the first transmission shaft 2 and the second transmission shaft 4 and the two fixing plates 1. A bearing lubrication structure 6 is installed on the fixing plate 1. The bearing lubrication structure 6 includes two sealing components, a double-axis air cylinder 635, a glass box 61 and a water pump 622. Each sealing component includes two heat-conducting outer rings 610, two heat-conducting inner rings 611 and two rubber outer sleeves 621. Injection pipes 69 and a fourth diversion pipe 625 are inserted into the outer sides of the two heat-conducting outer rings 610 in one of the sealing components. A telescopic diversion component is arranged between one side of the two injection pipes 69 and the glass box 61. A pressure plate 612 and an elastic air storage member 613 are arranged outside the injection pipe 69. The elastic air storage member 613 is communicated with a pneumatic telescopic rod 617. The piston end of the pneumatic telescopic rod 617 is fixedly connected with a sealing plate 619.
[0021] Specifically, a first transmission shaft 2 and a second transmission shaft 4 are arranged between the two fixing plates 1. Ball bearings 7 are fixedly connected between the outer sides of the first transmission shaft 2 and the second transmission shaft 4 and the two fixing plates 1. The outer ring of the ball bearing 7 is fixedly connected with the fixing plate 1, and the inner ring of the ball bearing 7 is fixedly connected with the first transmission shaft 2 or the second transmission shaft 4, enabling the first transmission shaft 2 and the second transmission shaft 4 to rotate. Fixed sleeves 3 are fixedly sleeved on both outer ends of the first transmission shaft 2, and fixed sleeves 5 are fixedly sleeved on both outer ends of the second transmission shaft 4. The gears 3 and 5 on the same side are meshed with each other. Connect a motor to the first transmission shaft 2 or the second transmission shaft 4, that is, control the rotation of the first transmission shaft 2 and the second transmission shaft 4 to provide power for the operation of the jacquard machine. Specifically, reference can be made to the invention document disclosed in the patent application number: 201110164298.6 for an electronic jacquard machine knife transmission mechanism, which will not be elaborated here.
[0022] Specifically, as Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, a bearing lubrication structure 6 is installed on the fixed plate 1 to automatically grease and lubricate 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. Each sealing component includes two heat-conducting outer rings 610, two heat-conducting inner rings 611 and two rubber outer sleeves 621. Two bearing installation grooves 8 are opened on the outer side of the fixed plate 1. The ball bearings 7 correspond to the bearing installation grooves 8 one by one. The ball bearings 7 are embedded inside the bearing installation grooves 8. The two heat-conducting outer rings 610 are aligned with the two bearing installation grooves 8. Among them, the heat-conducting outer ring 610 is rotatably sleeved on the outer side of the heat-conducting outer ring 610 on the same side. The two rubber outer sleeves 621 in one sealing component are respectively fixedly sleeved on the first transmission shaft 2 and the second transmission shaft 4. One end of the rubber outer sleeve 621 extends into the bearing installation groove 8 and abuts against the inner ring of the ball bearing 7. A second connecting plate 620 is fixedly connected between the two heat-conducting outer rings 610 in one sealing component. There are two second connecting plates 620 in one bearing lubrication structure 6. The two piston ends of the double-axis air cylinder 635 are respectively fixedly connected to the two second connecting plates 620. The double-axis air cylinder 635 is fixedly arranged through the outer shell of the fixed plate 1 and is fixedly connected to the fixed plate 1. Expansion rods three 636 are arranged on both sides of the double-axis air cylinder 635. The outer shell of the expansion rod three 636 is fixedly connected to one of the second connecting plates 620. The piston end of the expansion rod three 636 is fixedly connected to the other second connecting plate 620. The double-axis air cylinder 635 and the two expansion rods three 636 are arranged through the fixed plate 1. Under the action of the double-axis air cylinder 635 and the two expansion rods three 636, the two second connecting plates 620 can only move back and forth. By controlling the double-axis air cylinder 635 to work and contract, the two second connecting plates 620 approach each other, and the two sealing components approach each other. By controlling the double-axis air cylinder 635 to extend, the two sealing components move away from each other.
[0023] Specifically, such as Figure 1 、 Figure 5 、 Figure 6 、 Figure 9 、 Figure 10 and Figure 12As shown, injection tubes 69 and diversion pipelines 625 are inserted into two heat-conducting outer rings 610 in a sealing assembly arranged on one side of the fixing plate 1. A telescopic diversion assembly is arranged between one side of the two injection tubes 69 and the glass box 61. Two three-way valves 67 in the telescopic diversion assembly are fixedly communicated with one side of the glass box 61. The normal open ends of the three-way valves 67 are fixedly communicated with the bottom of the inner cavity of the glass box 61. Both of the two three-way valves 67 are fixedly connected with a first diversion pipeline 68. A third telescopic tube 641 is fixedly connected between one end of the first diversion pipeline 68 and the adjacent injection tube 69. A connecting frame 640 is fixedly sleeved on the outer side of the third telescopic tube 641. The piston end of a pneumatic cylinder 638 fixedly connected to the outer side of the first diversion pipeline 68 is fixedly connected with the connecting frame 640. Since the third telescopic tube 641 can be telescopically moved back and forth, by controlling the operation of the pneumatic cylinder 638, the position of the injection tube 69 can be controlled, and the relative position between the injection tube 69 and the heat-conducting outer ring 610 can be controlled, ensuring the stable and efficient cooperation between the injection tube 69 and the heat-conducting outer ring 610.
[0024] A second diversion pipeline 623 is fixedly connected to the water inlet end of the water pump 622. The second diversion pipeline 623 is used to connect to a water supply system. A third diversion pipeline 624 is fixedly connected to the water outlet end of the water pump 622. The two ends of the third diversion pipeline 624 are respectively fixedly communicated with the normally closed ends of the two three-way valves 67. After controlling the normally closed ends of the three-way valves 67 to work and open, water can be filled into the two first diversion pipelines 68.
[0025] A piston 63 is slidably inserted into the glass box 61. The top end of the piston 63 is arranged outside the glass box 61 and fixedly connected with a first connecting plate 64. A first telescopic rod 65 and a pneumatic cylinder 66 are fixedly inserted into the fixing plate 1. The piston ends of the first telescopic rod 65 and the pneumatic cylinder 66 are both fixedly connected with the first connecting plate 64. Under the action of the pneumatic cylinder 66 and the first telescopic rod 65, the first connecting plate 64 can move up and down. A solenoid valve 62 is fixedly communicated with the top of one side of the glass box 61. By controlling the solenoid valve 62 to work and open, lubricating grease can be replenished into the glass box 61.
[0026] Specifically, such as Figure 9 、 Figure 10 and Figure 11As shown, the pressure plate 612 and the elastic air 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 they move synchronously. The elastic air storage member 613 is fixedly connected to the heat-conducting outer ring 610. Guide holes 614 are provided on both the pressure plate 612 and the elastic air storage member 613. The guide rod 615 fixedly connected inside the heat-conducting outer ring 610 penetrates through the two guide holes 614. The guide rod 615 plays a role in guiding the movement of the pressure plate 612. A gas guide elbow 616 is fixedly connected between one side of the elastic air storage member 613 and the air inlet end of the pneumatic telescopic rod 617. The piston end of the telescopic rod two 618 arranged on one side of the pneumatic telescopic rod 617 is fixedly connected to the sealing plate 619. Moreover, the outer shells of the pneumatic telescopic rod 617 and the telescopic rod two 618 are fixedly connected to the inner wall of the heat-conducting outer ring 610. When the pneumatic telescopic rod 617 and the telescopic rod two 618 move leftward, the sealing plate 619 can move up and down inside the heat-conducting outer ring 610.
[0027] Specifically, as Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 13 shown, the diversion pipeline four 625 is fixedly installed at the bottom outside the heat-conducting outer ring 610 and is communicated with the bottom of the inner cavity of the heat-conducting outer ring 610. The bottom end of the diversion pipeline four 625 is fixedly connected with a telescopic pipe one 626. The bottom end of the telescopic pipe one 626 is fixedly connected with a check valve 627. A diversion pipeline five 628 is fixedly connected between the two check valves 627. The telescopic pipe one 626 that can be telescoped meets the need for the up and down movement of the diversion pipeline five 628. Under the one-way conduction characteristic of the check valve 627, the liquid inside the diversion pipeline five 628 cannot flow into the telescopic pipe one 626. A telescopic pipe two 629 is fixedly connected to the bottom end of the diversion pipeline five 628. The bottom end of the telescopic pipe two 629 is fixedly connected with a sewage pump 630. Moreover, a square groove 639 is provided on the outside of the fixed plate 1. The sewage pump 630 is arranged inside the square groove 639 and is fixedly connected to the fixed plate 1. The outer shell of the pneumatic cylinder two 637 arranged inside the square groove 639 is fixedly connected to the fixed plate 1. Because the telescopic pipe two 629 can be telescoped up and down, the piston end of the pneumatic cylinder two 637 is fixedly connected to the diversion pipeline five 628. By controlling the operation of the pneumatic cylinder two 637, the up and down movement of the diversion pipeline five 628 can be controlled.
[0028] Sealing sleeves 1 632 are sleeved on both ends of the outer side of the guide pipe 5 628, a sealing sleeve 2 633 is arranged on the top of the sealing sleeve 1 632, and a plurality of drainage holes 631 are arranged inside the sealing sleeve 2 633, all of which are opened on the outer side of the guide pipe 5 628. The sealing sleeves 2 633 and the sealing sleeves 1 632 are fixedly installed on the fixed plate 1, and the two sealing sleeves 2 633 are respectively arranged at the bottom of the two ball bearings 7 on the fixed plate 1 where the bearing lubrication structure 6 is located, and a confluence groove 634 is arranged at the bottom of the inner cavity of the bearing mounting groove 8, and the confluence groove 634 is opened on the fixed plate 1 and communicated with the sealing sleeves 2 633, so that there is a waste discharge space at the bottom of the outer ring of the ball bearing 7.
[0029] Specifically, the jacquard machine and the bearing lubrication structure 6 are connected to a human-machine interaction device to control their automated work, which is a public technical application and will not be described in detail here.
[0030] 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: 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 66 to work and stretch to push the connecting plate 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.
[0031] 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 is rotatably installed with the heat-conducting outer ring 610, 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; in 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 partially penetrating the heat-conducting outer ring 610.
[0032] Subsequently, control the normally closed ends of the two three-way valves 67 in the bearing lubrication structure 6 to open. At this time, the two three-way valves 67 are connected to the third diversion pipeline 624. Control the water pump 622 to work. The water pump 622 fills the first diversion pipeline 68, the third telescopic pipe 641, and the injection pipe 69 with water through the two three-way valves 67 in the third diversion pipeline 624. After a period of time, the water pump 622 pauses working. After the water flushes and cleans the residual grease lubricant in the first diversion pipeline 68, the third telescopic pipe 641, and the injection pipe 69, the grease lubricant and water enter the internally sealed bearing installation groove 8. At this time, control the first transmission shaft 2 and the second transmission shaft 4 to rotate at a low speed. The inner rings of the ball bearings 7 fixed to the rotating first transmission shaft 2 and the second transmission shaft 4 rotate. There is relative movement between the inner and outer rings of the ball bearings 7. The mixture of the grease lubricant and water is stirred, so that the water containing a certain amount of grease lubricant cleans the inside of the ball bearings 7. While ensuring lubrication and protection between the inner and outer rings of the ball bearings 7 and the balls, the impurities between the inner and outer rings of the ball bearings 7 are washed out, ensuring the high efficiency of maintenance during the operation of the ball bearings 7, and making use of the residual grease lubricant in the first diversion pipeline 68, the third telescopic pipe 641, and the injection pipe 69 to reduce waste of resources; Subsequently, control the second air cylinder 637 to work for a period of time. The fifth diversion pipeline 628 moves down a certain distance, so that the fifth diversion pipeline 628 moves down and leaves the inside of the second sealing sleeve 633. The drain hole 631 moves out of the inside of the second sealing sleeve 633. At this time, the sewage inside the bearing installation groove 8 enters the fifth diversion pipeline 628 through the confluence groove 634, the second sealing sleeve 633, and the drain hole 631 for storage, and uses the grease lubricant for lubricating the ball bearings 7 to complete the protective cleaning work of the ball bearings 7; Control the second air cylinder 637 to push the fifth diversion pipeline 628 to reset. Control the normally open end of the three-way valve 67 to open. Control the first air cylinder 66 to work at low power to drive the piston 63 to move down slowly. The grease lubricant inside the glass box 61 is under low pressure, and the grease lubricant slowly enters the first diversion pipeline 68. After the three-way valve 67 and the first air cylinder 66 work for a period of time, they pause working; perform the above-mentioned protective cleaning work of the ball bearings 7 again. After performing the protective cleaning of the ball bearings 7 2 to 4 times, complete the preliminary maintenance work of the ball bearings 7.
[0033] Subsequently, the double-axis air cylinder 635 is controlled to work and contract again, causing the heat-conducting outer ring 610 to continue moving into the bearing installation groove 8. The third air cylinder 638 works synchronously with the double-axis air cylinder 635, and the relative position between the injection pipe 69 and the heat-conducting outer ring 610 remains unchanged. Finally, the heat-conducting outer ring 610 abuts against the outer ring of the ball bearing 7, the heat-conducting inner ring 611 abuts against the inner ring of the ball bearing 7, one end of the injection pipe 69 is partially inserted between the inner and outer rings of the ball bearing 7, and the two sealing components enter the material-blocking state under the action of the double-axis air cylinder 635. The remaining positions between the inner rings of the ball bearing 7 are blocked by the cooperation of the heat-conducting outer ring 610 and the heat-conducting inner ring 611, and the gap between the inner and outer rings of the ball bearing 7 is blocked and sealed. Subsequently, the first air cylinder 66 is controlled to work to push the piston 63 to move downward slowly for a certain distance, so that the injection pipe 69 is filled with grease lubricant. Then, the first air cylinder 66 is controlled to move downward quickly for a short distance, so that the grease lubricant in the glass box 61 is under high pressure in a short time. The injection pipe 69 sprays part of the grease lubricant between the inner and outer rings of the ball bearing 7. The inner ring of the ball bearing 7 rotates to disperse the grease lubricant. The first air cylinder 66 works multiple times, and the injection pipe 69 sprays a certain amount of grease lubricant 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 lubricated and maintained evenly and efficiently. And under the action of the two sealing components, the grease lubricant will not splash with the rotation of the inner ring of the ball bearing 7. While reducing the waste of grease lubricant, it avoids contaminating the fabric during the maintenance of the ball bearing 7 with grease lubricant. The lubrication and maintenance work of the ball bearing 7 can be completed under the normal working condition of the jacquard machine, reducing the cost input for the maintenance of the ball bearing 7.
[0034] Finally, the sewage pump 630 is controlled to work to drain the wastewater in the fifth diversion pipeline 628, and then the bearing lubrication structure 6 is controlled to return to its initial state.
[0035] 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 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 of 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 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, the air pressure inside the elastic gas storage member 613 increases, and 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 stretches 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 to meet 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, and 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 the ball bearing 7 to ensure the service life of the ball bearing 7.
[0036] 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 the sewage pump 630 is controlled to discharge the water.
[0037] Finally, the control pneumatic cylinder three 638 works to push the injection tube 69 to move 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.
