Description

Technical Field

[0001] The present application relates to the technical field of textile machinery, and in particular to a cam rotating mechanism of an electronic jacquard machine with stable operation. Background Art

[0002] Electronic jacquard machine is a kind of equipment that realizes jacquard weaving by electronic control technology. It controls the interweaving of warp and weft yarns of various colors to form complex patterned fabrics. Compared with traditional mechanical jacquard machines, electronic jacquard machines have the advantages of easy operation, high reliability and low production cost, and are an important development direction of the modern textile industry.

[0003] In the related technology, reference can be made to the Chinese utility model patent with authorization announcement number CN219450029U, which discloses a double cam needle lifting mechanism for an electronic jacquard machine, belonging to the technical field of jacquard machine equipment; by setting two groups of cam roller groups, the upper cam roller group cooperates with the lower cam roller group to realize the up and down swinging of the swing plate group, and the angle between the multiple cams in the two groups of cam roller groups is set to 120°. After the cam in the upper cam roller group presses down the swing plate group, the cam in the lower cam roller group will continuously and smoothly push the swing plate group upward, thereby avoiding vibration when the swing plate group swings up and down.

[0004] In the actual working process of the double cam needle lifting mechanism of the above-mentioned electronic jacquard machine, the friction at the rotating shaft of the cam roller group will increase due to gradual drying after long-term work, thereby slowing down or making the rotation of the rotating shaft not smooth. The service life of the rotating shaft is reduced, which has an adverse effect on the weaving ability of the needle lifting. Summary of the invention

[0006] The present application provides a stable electronic jacquard machine cam rotating mechanism, which adopts the following technical solution:

[0007] A cam rotating mechanism of an electronic jacquard machine with stable operation comprises a frame and a cam roller group rotatably arranged on the frame, wherein a lubricating device for stably lubricating a rotating shaft of the cam roller group is arranged on the frame, and the lubricating device comprises:

[0009] An oil spray nozzle, the oil spray nozzle is arranged on the mounting ring, the mounting ring is provided with a lubrication channel connected to the oil storage cavity, the oil spray nozzle is connected to the lubrication channel, a plurality of the oil spray nozzles are arranged along the inner ring wall of the mounting ring, and the plurality of the oil spray nozzles spray oil to the rotating shaft;

[0010] The switch mechanism is arranged on the mounting ring and is used to control the opening and closing of the lubrication channel.

[0011] By adopting the above technical solution, a mounting ring storing lubricating oil is installed on the rotating shaft, and the lubrication channel is opened by a switch mechanism, so that the lubricating oil can be evenly sprayed onto the rotating shaft through an oil spray nozzle, thereby lubricating the rotation of the rotating shaft, ensuring that the rotating shaft can always maintain stable rotation, reducing the wear of the rotating shaft during long-term rotation, increasing the service life of the rotating shaft, and ensuring the continuous and accurate weaving ability of the needle lifting.

[0012] Optionally, the switch mechanism includes:

[0013] A switch door, the switch door is radially slidably arranged on the mounting ring along the lubrication channel, and the switch door is made of magnetic material;

[0014] A switch spring, wherein the switch spring is arranged on the mounting ring and connected to the switch door, and the switch door closes the lubrication channel under the action of the switch spring;

[0015] An electromagnetic door suction, wherein the electromagnetic door suction is arranged on the mounting ring and is located on the inner side wall of the lubrication channel. When the electromagnetic door suction absorbs the switch door, the switch door opens the lubrication channel;

[0016] A control component is arranged on the frame and is used to control the power supply condition of the electromagnetic door suction.

[0017] By adopting the above technical scheme, when the rotating shaft is not working, the switch door closes the lubrication channel under the action of the switch spring, and the oil nozzle does not spray oil on the rotating shaft, thereby avoiding waste of lubricating oil; when the rotating shaft rotates, the control component controls the electromagnetic door suction to be energized, and after the electromagnetic door suction is energized, it adsorbs the switch door to compress the switch spring to move, so that the switch door opens the lubrication channel, and the lubricating oil enters the oil nozzle through the lubrication channel, and the oil nozzle can spray the lubricating oil on the rotating shaft, thereby completing the lubrication work of the rotating shaft.

[0018] Optionally, the control component includes:

[0019] Two permanent magnets, both of which are arranged on the frame and are respectively located on both sides of the rotating shaft, and the two ends of the two permanent magnets close to each other have opposite magnetic poles;

The rotation of the armature cuts the magnetic field between the two permanent magnets to generate current on the brush and energize the electromagnetic door suction. Therefore, while the rotating shaft is rotating, the electromagnetic door suction can be kept in a powered state, so that the fuel injector can continuously add lubricating oil to the rotating shaft while the rotating shaft is rotating, and automatically stop refueling after the rotating shaft stops rotating. No manual operation is required, which is convenient and fast, and no additional power supply is required, which is energy-saving and environmentally friendly.

The extrusion plate performs centrifugal motion under the action of centripetal force. The extrusion plate stretches the extrusion spring to move, pushing the lubricating oil into the lubrication channel, thereby completing the oil pushing work while the mounting ring rotates; when the mounting ring does not rotate, the extrusion plate moves back to its original position under the action of the extrusion spring and draws part of the lubricating oil in the lubrication channel back to the oil storage chamber, reducing the waste of lubricating oil.

[0027] Optionally, a counterweight block is provided on the extrusion plate.

[0028] By adopting the above technical solution, a counterweight block is installed on the extrusion plate, thereby increasing the displacement of the extrusion plate during centrifugal motion and improving the pushing effect of the extrusion plate on the lubricating oil.

[0030] An air blowing pipe, which is rotatably arranged on the frame and is connected to an air source;

[0031] A moving assembly, which is arranged on the frame and is used to drive the air blowing pipe to move, and the air blowing pipe moves around the rotating shaft under the action of the moving assembly;

[0032] A ventilation component is arranged on the frame and is used for controlling the ventilation of the blowing tube.

[0033] By adopting the above technical solution, the air blowing pipe is rotatably installed on the frame through the moving component, and after the ventilation component is controlled to allow the air blowing pipe to be ventilated, the air blowing pipe blows air around the rotating shaft under the action of the moving component. The air blowing pipe blows the lubricating oil on the rotating shaft evenly and cools down the heat generated when the rotating shaft rotates, thereby increasing the service life of the rotating shaft.

[0034] Optionally, the mobile component includes:

[0035] A movable column, wherein the movable column is mounted on the mounting ring by sliding along the radial direction of the mounting ring;

[0037] The movable gear ring is rotatably arranged on the frame, the inner ring wall of the movable gear ring is provided with teeth, and the air blowing pipe is arranged on the movable gear ring.

[0038] By adopting the above technical solution, the moving column performs centrifugal motion as the mounting ring rotates, and the movement of the moving column drives the moving half ring to engage with the moving gear ring. After the moving half ring engages with the moving gear ring, the movement of the moving half ring drives the moving gear ring to rotate, and the rotation of the moving gear ring drives the blowing pipe to move, thereby realizing the rotation of the blowing pipe position.

[0039] Optionally, the ventilation component includes:

[0040] An elastic cavity, wherein the elastic cavity is arranged on the blowing tube;

[0041] A baffle, the baffle being rotatably disposed on the air blowing pipe, the baffle being located at a connection point between the elastic cavity and the air blowing pipe;

[0042] A control rod, wherein the control rod is rotatably arranged on the air blowing pipe, one end of the control rod is rotatably connected to the elastic cavity, and the other end of the control rod is rotatably connected to the baffle;

[0043] An extrusion piece is arranged on the frame and is used for extruding the elastic cavity.

[0044] By adopting the above technical solution, when the air blowing pipe needs to be ventilated, the elastic cavity is squeezed by using an extrusion piece, the deformation of the elastic cavity drives the control rod to rotate, the rotation of the control rod drives the baffle to move, and the movement of the baffle makes the elastic cavity connected with the air blowing pipe, thereby realizing the ventilation work of the air blowing pipe.

[0045] Optionally, the extrusion member comprises:

[0046] A magnet block, wherein the magnet block is arranged in the elastic cavity;

[0047] An electromagnetic block, wherein the electromagnetic block is arranged in the elastic cavity, and one end of the control rod located in the elastic cavity is rotatably arranged on the electromagnetic block;

[0048] A resistor bar, wherein the resistor bar is arranged on the movable gear ring;

[0049] A power-on plate, which is slidably disposed on the resistor bar and is electrically connected to the electromagnetic block through the resistor bar;

[0050] A return spring is arranged on the movable gear ring and connected to the power-carrying plate. When the return spring is in a normal state, the power-carrying plate is located at the position where the resistance of the resistor strip is the largest under the action of the return spring.

[0051] By adopting the above technical solution, when the rotating shaft rotates, the rotating shaft rotates to drive the movable gear ring to rotate, and the rotating gear ring drives the power-carrying plate to stretch the reset spring to perform centrifugal motion. After the power-carrying plate moves, the resistance value of the resistor bar decreases, and the amount of electricity passed to the electromagnetic block by the power-carrying plate increases, and the magnetism of the electromagnetic block increases accordingly. The electromagnetic block attracts the magnet blocks to approach each other. When the electromagnetic block and the magnet block approach each other, they squeeze the elastic cavity to deform, thereby completing the squeezing of the elastic cavity while the rotating shaft rotates.

[0052] In summary, the present application includes at least one of the following beneficial technical effects:

[0053] 1. By installing a mounting ring storing lubricating oil on the rotating shaft and opening the lubrication channel through the switch mechanism, the lubricating oil can be evenly sprayed onto the rotating shaft through the oil spray nozzle, thereby lubricating the rotating shaft, ensuring that the rotating shaft can always maintain stable rotation, reducing the wear of the rotating shaft during long-term rotation, increasing the service life of the rotating shaft, and ensuring the continuous and accurate weaving ability of the needle lifting;

[0060] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0061] The embodiment of the present application discloses a cam rotating mechanism of an electronic jacquard machine with stable operation.

[0062] Reference Figure 1 The cam rotating mechanism of the electronic jacquard machine with stable operation includes a frame 1 and a cam roller group 11 rotatably mounted on the frame 1. The frame 1 is provided with a lubricating device 2 for stably lubricating a rotating shaft 12 of the cam roller group 11.

[0063] Reference Figure 1 and Figure 2 The lubricating device 2 comprises a mounting ring 21, an oil spray nozzle 22 and a switch mechanism 23. The mounting ring 21 is fixedly mounted on the rotating shaft 12, and the mounting ring 21 rotates with the rotation of the rotating shaft 12.

[0064] Reference Figure 2 and Figure 3 The mounting ring 21 has an oil storage chamber 24 inside, and lubricating oil is stored in the oil storage chamber 24 of the mounting ring 21. The oil spray nozzle 22 is fixedly mounted on the inner ring wall of the mounting ring 21. The mounting ring 21 has a lubrication channel 25 inside, and the two ends of the lubrication channel 25 are respectively connected to the oil storage chamber 24 and the oil spray nozzle 22. The switch mechanism 23 is arranged on the mounting ring 21 and is used to control the opening and closing of the lubrication channel 25.

[0065] Reference Figure 2 and Figure 3 The switch mechanism 23 includes a switch door 26, a switch spring 27, an electromagnetic door suction 28 and a control component 29. The switch door 26 is mounted on the mounting ring 21 to slide radially along the lubrication channel 25. The switch door 26 is a switch door 26 made of magnetic material. The switch spring 27 is fixedly mounted on the mounting ring 21 and connected to the switch door 26. The switch door 26 closes the lubrication channel 25 under the action of the switch spring 27. The electromagnetic door suction 28 is fixedly mounted on the inner wall of the lubrication channel 25. When the electromagnetic door suction 28 adsorbs the switch door 26, the switch door 26 compresses the switch spring 27 and opens the lubrication channel 25. The control component 29 is arranged on the frame 1 and is used to control the power supply of the electromagnetic door suction 28.

[0066] Reference Figure 1 and Figure 2 The control assembly 29 includes two permanent magnets 31, a commutator and a brush. The two permanent magnets 31 are fixedly mounted on the frame 1 and are respectively located on both sides of the rotating shaft 12. The commutator is fixedly mounted on the outer wall of the mounting ring 21 close to the two permanent magnets 31. An armature 32 is fixedly mounted on the commutator. The armature 32 is located between the two permanent magnets 31. The brush is fixedly mounted on the frame 1, and the brush contacts the commutator and is electrically connected to the electromagnetic door suction 28.

[0067] Reference Figure 2 and Figure 3 When the rotating shaft 12 is not working, the switch door 26 closes the lubrication channel 25 under the action of the switch spring 27, and the oil spray nozzle 22 does not spray oil on the rotating shaft 12, thereby avoiding the waste of lubricating oil. When the rotating shaft 12 rotates, the rotating shaft 12 drives the mounting ring 21 to rotate, and the mounting ring 21 drives the commutator and the armature 32 to rotate. The armature 32 rotates to cut the magnetic field between the two permanent magnets 31 to generate current on the brush and energize the electromagnetic door suction 28. After the electromagnetic door suction 28 is energized, it absorbs the switch door 26 and compresses the switch spring 27 to move, so that the switch door 26 opens the lubrication channel 25, and the lubricating oil enters the oil spray nozzle 22 through the lubrication channel 25. The oil spray nozzle 22 can spray the lubricating oil on the rotating shaft 12, thereby completing the lubrication work of the rotating shaft 12.

[0068] Reference Figure 2 and Figure 3 The mounting ring 21 is provided with an oil squeezing mechanism 4 for squeezing the lubricating oil in the oil storage chamber 24, and the oil squeezing mechanism 4 includes a squeezing plate 41 and a squeezing spring 42. An squeezing chamber 43 communicating with the oil storage chamber 24 is provided inside the mounting ring 21.

A counterweight 44 is fixedly mounted on the squeezing plate 41.

[0069] Reference Figure 2 and Figure 3 The rotation of the mounting ring 21 drives the extrusion plate 41 to move accordingly. The extrusion plate 41 performs centrifugal motion under the action of the centripetal force. The extrusion plate 41 stretches the extrusion spring 42 to move, pushing the lubricating oil into the lubrication channel 25, thereby completing the oil pushing work while the mounting ring 21 rotates; when the mounting ring 21 does not rotate, the extrusion plate 41 moves back to its original position under the action of the extrusion spring 42 and draws part of the lubricating oil in the lubrication channel 25 back to the oil storage chamber 24, reducing the waste of lubricating oil.

[0070] Reference Figure 1 and Figure 2 The frame 1 is provided with a blowing mechanism 5 for blowing air to the rotating shaft 12, and the blowing mechanism 5 includes a blowing pipe 51, a moving assembly 52 and a ventilation assembly 53. The blowing pipe 51 is rotatably mounted on the frame 1 through the moving assembly 52 and is connected to the air source. The blowing pipe 51 moves around the rotating shaft 12 under the action of the moving assembly 52. ​​The ventilation assembly 53 is arranged on the frame 1 and is used to control the ventilation of the blowing pipe 51. The blowing pipe 51 blows the lubricating oil on the rotating shaft 12 evenly and cools down the heat generated when the rotating shaft 12 rotates, thereby increasing the service life of the rotating shaft 12.

[0071] Reference Figure 1 and Figure 2 The moving assembly 52 includes a moving column 54, a moving half ring 55 and a moving gear ring 56. The moving column 54 is mounted on the mounting ring 21 for radial sliding movement along the mounting ring 21. The moving half ring 55 is fixedly mounted on one end of the moving column 54 away from the mounting ring 21, and a side wall of the moving half ring 55 away from the mounting ring 21 is provided with teeth. The moving gear ring 56 is rotatably mounted on the frame 1, and a gear is provided on the inner ring wall of the moving gear ring 56, and the air blowing pipe 51 is fixedly mounted on the moving gear ring 56.

[0072] Reference Figure 2 As the mounting ring 21 rotates, the movable column 54 performs centrifugal motion. The movable column 54 moves to drive the movable half ring 55 to engage with the movable gear ring 56. After the movable half ring 55 engages with the movable gear ring 56, the movable half ring 55 moves to drive the movable gear ring 56 to rotate. The rotation of the movable gear ring 56 drives the blowing pipe 51 to move, thereby realizing the rotation of the position of the blowing pipe 51.

[0073] Reference Figure 1 and Figure 2The ventilation assembly 53 includes an elastic cavity 61, a baffle 62, a control rod 63 and an extrusion member 64. The elastic cavity 61 is fixedly mounted on the air blowing pipe 51. The baffle 62 is rotatably mounted inside the air blowing pipe 51, and the baffle 62 is located at the connection between the elastic cavity 61 and the air blowing pipe 51. The control rod 63 is rotatably mounted inside the air blowing pipe 51, one end of the control rod 63 is rotatably connected to the elastic cavity 61, and the other end of the control rod 63 is rotatably connected to the baffle 62. The extrusion member 64 is arranged on the frame 1 and is used to extrude the elastic cavity 61.

[0074] Reference Figure 2 The extrusion member 64 includes a magnet block 65, an electromagnetic block 66, a resistor bar 67, a power-on plate 68 and a return spring 69. The magnet block 65 is fixedly mounted in the elastic cavity 61. The electromagnetic block 66 is fixedly mounted in the elastic cavity 61, and one end of the control rod 63 located in the elastic cavity 61 is rotatably mounted on the electromagnetic block 66. The resistor bar 67 is fixedly mounted on the moving gear ring 56. The power-on plate 68 is slidably mounted on the resistor bar 67 and is electrically connected to the electromagnetic block 66 through the resistor bar 67. The return spring 69 is fixedly mounted on the moving gear ring 56 and is connected to the power-on plate 68. When the return spring 69 is in a normal state, the power-on plate 68 is located at the point where the resistance of the resistor bar 67 is the largest under the action of the return spring 69.

[0075] Reference Figure 1 and Figure 2 When the rotating shaft 12 rotates, the rotating shaft 12 rotates and drives the moving gear ring 56 to rotate. The moving gear ring 56 rotates and drives the power-on plate 68 to stretch the reset spring 69 to perform centrifugal motion. After the power-on plate 68 moves, the resistance value of the resistor bar 67 decreases, and the amount of electricity supplied to the electromagnetic block 66 by the power-on plate 68 increases. The magnetism of the electromagnetic block 66 increases accordingly, and the electromagnetic block 66 attracts the magnet block 65 to approach each other. When the electromagnetic block 66 and the magnet block 65 approach each other, they squeeze the elastic cavity 61 to deform. The deformation of the elastic cavity 61 drives the control rod 63 to rotate, and the rotation of the control rod 63 drives the baffle 62 to move. The movement of the baffle 62 makes the elastic cavity 61 communicate with the air blowing pipe 51, thereby realizing the ventilation work of the air blowing pipe 51.

[0076] The working principle of the embodiment of the present application is as follows:

[0077] A mounting ring 21 storing lubricating oil is installed on the rotating shaft 12. When the rotating shaft 12 rotates, the electromagnetic door suction 28 adsorbs the switch door 26 to open the lubrication channel 25, and the lubricating oil can be evenly sprayed onto the rotating shaft 12 through the oil nozzle 22, thereby lubricating the rotation of the rotating shaft 12, ensuring that the rotating shaft 12 can always maintain stable rotation, reducing the wear of the rotating shaft 12 during long-term rotation, increasing the service life of the rotating shaft 12, and ensuring the continuous and accurate weaving ability of the needle lifting.

[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
