Description

Technical Field

[0001] The invention relates to the technical field of electronic jacquard machines, in particular to an opening component of an electronic jacquard machine. Background Art

[0002] Electronic jacquard machine is an important equipment in the textile industry, and its opening component plays a vital role in the jacquard process. The opening component of the traditional electronic jacquard machine is usually driven by a cam mechanism or a crank connecting rod mechanism to realize the opening and closing movement of the jacquard machine. However, these mechanical mechanisms have the following significant problems during operation:

[0003] 1. Poor operation stability: Due to the weight of the equipment and the limitation of the mechanism design, the cam mechanism and the crank connecting rod mechanism are prone to large mechanical vibration during operation. This vibration not only affects the stable operation of the equipment, but also may cause the jacquard precision to decrease, affecting the quality of the final fabric.

[0004] 2. It is difficult to eliminate the lateral force: The characteristics of the mechanical structure determine that when the machine moves in the vertical direction, there is often a certain lateral force. This lateral force can easily cause the equipment to jump horizontally during operation, affecting the accuracy and consistency of the jacquard operation.

[0005] 3. Instability of motor drive: In motor-driven jacquard machines, the motor often experiences fluctuations in output speed and torque during the startup phase. This fluctuation will be transmitted to the shedding component, causing unstable operation and affecting the precise control of the shedding, thus adversely affecting the jacquard effect.

[0006] 4. Lack of efficient locking mechanism: Current jacquard machines often lack effective locking mechanisms when they are stopped, which may cause unnecessary movement of the equipment when it is impacted by external forces. This movement not only threatens the overall stability of the equipment, but may also cause deviations in the jacquard process, affecting production efficiency and product quality. Summary of the invention

DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example

[0052] See also Figure 1 , 2 11. An opening assembly of an electronic jacquard machine includes an assembly frame 1 and an upper connecting bracket 201, a lower connecting bracket 202, a linkage assembly 3, a driving assembly, and a posture adjustment assembly 5 installed in the assembly frame 1.

[0053] An upper connecting bracket 201 and a lower connecting bracket 202 are slidably mounted on the assembly frame 1, both of which maintain lifting movement in the vertical direction. The upper connecting bracket 201 is arranged above the lower connecting bracket 202, and the upper connecting bracket 201 and the lower connecting bracket 202 are respectively equipped with the upper knife box and the lower knife box of the motor jacquard machine.

[0054] The linkage component 3 is linked with the upper connecting bracket 201 and the lower connecting bracket 202 , and the upper connecting bracket 201 and the lower connecting bracket 202 maintain synchronous reverse lifting and lowering motions through the action of the linkage component 3 .

[0055] The driving assembly includes a swing arm 41, a lifting seat 42, a rotating disk 43, and a driving motor 44. The swing arm 41 is linked with the lower connecting bracket 202 and the lifting seat 42, the lifting seat 42 is linked with the rotating disk 43, and the rotating disk 43 is poweredly connected with the driving motor 44.

[0056] The posture adjustment component 5 is assembled between the rotating disk 43 and the driving motor 44 , and is used to control the power transmission posture between the driving motor 44 and the rotating disk 43 and the locking posture of the rotating disk 43 .

[0057] The assembly frame 1 is made of metal plates as the base material and is assembled by cutting and welding. It can ensure its own structural strength and stability to ensure that the upper connecting bracket 201, the lower connecting bracket 202, the linkage component 3, the drive component, and the posture adjustment component 5 are stably installed and operated therein, thereby realizing the design function of the electronic jacquard machine opening component.

[0058] The setting of the linkage component 3 can ensure that the upper connecting bracket 201 and the lower connecting bracket 202 can stably move up and down in the assembly frame 1, and ensure that the upper connecting bracket 201 and the lower connecting bracket 202 always maintain reverse operation. When the lower connecting bracket 202 moves down, the upper connecting bracket 201 keeps rising, and when the lower connecting bracket 202 moves up, the upper connecting bracket 201 keeps descending. The upper and lower knife boxes assembled on the upper connecting bracket 201 and the lower connecting bracket 202 maintain synchronous and symmetrical movement, thereby realizing the opening and closing movement of the opening component, meeting the functional design requirements.

[0059] When the upper connecting bracket 201 drives the upper knife box to the bottom of the stroke, and the lower connecting bracket 202 drives the lower knife box to the top of the stroke, the distance between the upper knife box and the lower knife box is the smallest. At this time, all the sheet hooks are subjected to the upward thrust of the broach, so that the square hole at the upper end of the sheet hook is slightly higher than the hook of the needle selection solenoid valve. When the corresponding solenoid valve is energized, the sheet hook is deflected by the suction force of the solenoid valve, so that the square hole of the sheet hook overlaps with the hook of the solenoid valve in space.

[0060] When the upper knife box moves upward and the lower knife box moves downward, the sucked hooks are suspended on the hooks of the solenoid valve and move upward with the upper knife box, together with the corresponding healds, forming the upper warp yarn with opening movement; the remaining unselected hooks will descend with the lower knife box together with the corresponding healds to form the lower warp yarn with opening movement.

[0061] When the upper knife box is at the top of the stroke and the lower knife box is at the bottom of the stroke, the maximum opening of the warp yarn is obtained. The arrangement rules of the upper warp yarn and the lower warp yarn are continuously changed according to the design requirements to obtain the required pattern fabric.

[0062] In the driving assembly, the operation of the driving motor 44 can drive the rotating disk 43 to operate, and the rotational movement of the rotating disk 43 drives the lifting seat 42 to realize the reciprocating lifting motion, and then the lifting seat 42 drives the swing arm 41 to swing back and forth, and the swing arm 41 drives the lower connecting bracket 202 to reciprocate and lift. Under the cooperation of the linkage assembly 3, the upper connecting bracket 201 and the lower connecting bracket 202 can maintain reverse synchronous lifting and lowering motion.

[0063] When the posture adjustment component 5 is in operation, the power transmitted from the drive motor 44 to the rotating disk 43 can be cut off, and the rotating disk 43 can be locked at the same time to ensure that the upper connecting bracket 201 and the lower connecting bracket 202 that are linked with the rotating disk 43 are locked and positioned, which is convenient for disassembly and maintenance of the opening component and can ensure the stability of each component of the opening component when it is stopped. When the posture adjustment component 5 controls the power transmission of the drive motor 44 to the rotating disk 43, the locking posture of the rotating disk 43 can be cancelled to ensure that the rotating disk 43 receives the power of the drive motor 44 and operates normally, thereby driving the lower connecting bracket 202 to achieve reciprocating lifting and lowering motion.

[0064] See also Figure 1-3 In order to ensure the structural strength and stability of the assembly rack 1 and to ensure that other components can be stably installed and operated on the assembly rack 1, the following technical solutions are provided.

[0065] The assembly rack 1 includes an assembly base plate 11, an assembly side plate 12, an assembly top plate 13, an assembly baffle 14, and an assembly cover plate 15. The assembly side plate 12 includes two groups fixedly installed on the assembly base plate 11 and arranged in the vertical direction. The upper connecting bracket 201 and the lower connecting bracket 202 are slidably installed on the assembly side plate 12. A protective cover 16 is fixedly installed on the outer side of the assembly side plate 12. The linkage assembly 3 is arranged in the protective cover 16. The assembly top plate 13 is fixedly installed on the top of the two groups of assembly side plates 12.

The assembly side plate 12 and the assembly baffle 14 are spliced ​​and combined to form an assembly cavity 17. The assembly cover plate 15 is fixedly installed on the top of the assembly cavity 17.

[0066] The assembly bottom plate 11, the assembly side plate 12, and the assembly baffle 14 are fixedly assembled by assembly welding. The assembly side plate 12 and the assembly baffle 14 are arranged vertically to form an assembly cavity 17 arranged at the bottom of the assembly rack 1. The arrangement of the assembly bottom plate 11 can ensure that the opening component can be stably installed in the factory.

[0067] The assembly top plate 13 is fixedly connected between the two sets of assembly side plates 12 by bolts to improve the overall strength of the assembly frame 1, and the assembly cover plate 15 is also fixedly connected to the top of the two sets of assembly baffles 14 by bolts to isolate the top opening of the assembly cavity 17 from the external environment, so as to facilitate the stable installation of the drive component and the posture adjustment component 5 in the assembly cavity 17 and isolate them from the external environment.

[0068] The protective cover 16 is fixed to the outer surface of the assembly side plate 12 by bolts, so that the linkage component 3 can be assembled into the protective cover 16 and isolated from the external environment. The setting of the protective periphery, the assembly cavity 17 and the assembly cover plate 15 can hide the linkage component 3, the drive component and the posture adjustment component 5 to improve the cleanliness of the opening component, and at the same time avoid the leakage of oil in the linkage component 3, the drive component and the posture adjustment component 5 to affect the cleanliness of the factory and the fabric. Example

[0069] See also Figure 4 , 5 In order to ensure that the upper connecting bracket 201 and the lower connecting bracket 202 can be stably assembled on the two sets of assembly side panels 12 in a relatively sliding manner, and at the same time facilitate the disassembly and maintenance of the upper connecting bracket 201 and the lower connecting bracket 202, and facilitate the stable assembly of the upper knife box and the lower knife box on the upper connecting bracket 201 and the lower connecting bracket 202 respectively, the following technical solution is provided.

[0070] The upper connecting bracket 201 and the lower connecting bracket 202 both include a mounting frame plate 21, a reinforcing side plate 22, a connecting frame plate 23, and a mounting end plate 24. The mounting frame plate 21 is arranged between two sets of assembly side plates 12. Both ends of the reinforcing side plate 22 are fixedly connected to the mounting frame plate 21. The assembly side plate 12 is provided with a clearance through hole A121 arranged in the vertical direction. The connecting frame plate 23 is fixedly installed at both ends of the mounting frame plate 21 and penetrates the clearance through hole A121. The mounting end plate 24 is fixedly installed at the outer end of the connecting frame plate 23 and is arranged in the protective outer cover 16.

[0071] A guide rail 122 arranged in the vertical direction is fixedly connected to the outer side surface of the assembly side plate 12 , and a support wheel 241 is assembled on the installation end plate 24 , and the support wheel 241 is in a matching combination with the guide rail 122 .

[0072] The structural feature of the connecting frame plate 23 is that it can pass through the yield through hole A121 from the inner side of the assembly side plate 12, extend to the outer side of the assembly side plate 12, and be fixed and combined with the mounting end plate 24 on the outer side of the assembly side plate 12 by bolt fixing, so as to facilitate the installation of the connecting frame plate 23 and the mounting end plate 24 on the assembly side plate 12. The mounting frame plate 21 is installed between the two groups of connecting frame plates 23 by bolt fixing, and the reinforcing side plate 22 is fixed to the mounting frame plate 21 by bolt fixing, which can stably support the mounting frame plate 21 and strengthen the structural strength of the mounting frame plate 21 itself. A horizontally arranged connecting cross plate 211 is also welded on the front side of the mounting base plate, which can ensure that the upper knife box or the lower knife box is stably installed on the connecting cross plate 211.

[0073] The structural features of the upper connecting bracket 201 and the lower connecting bracket 202 can ensure that the upper connecting bracket 201 and the lower connecting bracket 202 are stably installed on the assembly side plate 12, and are convenient for disassembly, assembly and maintenance of the upper connecting bracket 201 and the lower connecting bracket 202.

[0074] Two groups of guide rails 122 arranged in the vertical direction are provided on the outer side of each assembly side plate 12, and four groups of support wheels 241 are installed on the installation end plate 24. The two groups of guide rails 122 are respectively matched with two groups of support wheels 241 arranged in the same vertical direction to ensure that the upper connecting bracket 201 and the lower connecting bracket 202 can be stably lifted and lowered in the vertical direction in the assembly rack 1.

[0075] A weight-reducing hole A212 and a weight-reducing hole B221 are respectively provided on the mounting frame plate 21 and the reinforcing side plate 22 to reduce the overall weight of the upper connecting bracket 201 and the lower connecting bracket 202 .

[0076] See also Figure 8-10 In order to ensure that the support wheel 241 can be stably combined with the guide rail 122 to realize the stable lifting of the upper connecting bracket 201 and the lower connecting bracket 202 along the guide rail 122, and at the same time avoid the support wheel 241 from rigidly colliding with the guide rail 122 during the lifting process of the upper connecting bracket 201 and the lower connecting bracket 202, thereby affecting the stability of the overall operation of the equipment, the following technical solution is provided.

[0077] An assembly bracket 242 is slidably installed on the mounting end plate 24, and an assembly screw 243 is fixedly connected to the assembly bracket 242 and is arranged to penetrate the mounting end plate 24. A support spring 244 is installed on the periphery of the assembly screw 243, and both ends of the support spring 244 are respectively kept in contact with the mounting end plate 24 and the assembly bracket 242. An adjusting nut 245 is screwed on the assembly screw 243 and is kept in contact with the mounting end plate 24. The support wheel 241 is rotatably installed on the assembly bracket 242.

[0078] The setting of the assembly screw 243 can ensure that the support spring 244 is stably installed, and the support spring 244 can drive the assembly bracket 242 and the support wheel 241 to move toward the corresponding guide rail 122 under the action of elastic force. In the process of the support wheel 241 rising and falling with the upper connecting bracket 201 and the lower connecting bracket 202, the support spring 244 can ensure that the support wheel 241 is always matched with the guide rail 122 and avoid rigid collision between the support wheel 241 and the guide rail 122, thereby making the upper connecting bracket 201 and the lower connecting bracket 202 rise and fall stably in the vertical direction.

[0079] The position of the assembly bracket 242 is adjusted by screwing the adjusting nut 245 to limit the assembly bracket 242 from further moving toward the side of the guide rail 122. The assembly bracket 242 and the support wheel 241 arranged on both sides of the upper connecting bracket 201 and the lower connecting bracket 202 work together to effectively avoid invalid lateral displacement of the upper connecting bracket 201 and the lower connecting bracket 202, so as to ensure stable cooperation of components such as the sheet hook, the broach, and the solenoid valve.

[0080] See also Figure 6 , 7 In order to ensure that the linkage assembly 3 can be stably connected to the upper connecting bracket 201 and the lower connecting bracket 202, so that the upper connecting bracket 201 and the lower connecting bracket 202 always maintain reverse synchronous lifting movement, the following technical solution is provided.

[0081] The linkage assembly 3 includes an upper transmission rack 31, a lower transmission rack 32, and a transmission gear 33. The upper transmission rack 31 is fixedly connected to both sides of the connecting frame plate 23 in the upper connecting bracket 201, and the lower transmission rack 32 is fixedly connected to both sides of the connecting frame plate 23 in the lower connecting bracket 202. The upper transmission rack 31 and the lower transmission rack 32 are arranged relatively to each other, and a transmission gear 33 is arranged between the upper transmission rack 31 and the lower transmission rack 32. The transmission gear 33 is meshed with the upper transmission rack 31 and the lower transmission rack 32, and the transmission gear 33 is rotatably installed on the outer side of the assembly side plate 12.

[0082] Two groups of ear seats 123 arranged side by side are fixedly connected to the middle of the outer wall of the assembly side plate 12, and a mounting shaft 331 is rotatably installed between the two groups of ear seats 123. The mounting shaft 331 is provided with two groups arranged side by side, and two groups of transmission gears 33 are fixedly connected to the two groups of mounting shafts 331. The two groups of transmission gears 33 are respectively meshed with the upper transmission rack 31 and the lower transmission rack 32 on both sides of the connecting frame plate 23. Each group of upper transmission rack 31 and lower transmission rack 32 are meshed and connected with two groups of transmission gears 33, which can ensure that the upper transmission rack 31 and the lower transmission rack 32 maintain reverse lifting and lowering motion under the action of the transmission gear 33.

[0083] When the lower connecting bracket 202 is driven by the driving assembly to rise or fall, it can drive the lower transmission rack 32 to move up and down synchronously, and then drive the upper transmission rack 31 and the upper connecting bracket 201 to always maintain reverse lifting movement under the action of the transmission gear 33, thereby realizing the reverse synchronous lifting movement of the upper connecting bracket 201 and the lower connecting bracket 202.

[0084] An upper connecting seat 311 is fixedly connected to the top of the upper transmission rack 31, and the upper connecting seat 311 is fixedly connected to the side wall of the connecting frame plate 23 in the upper connecting bracket 201 by bolts, and an upper guide rod 312 arranged vertically downward is fixedly connected to the upper connecting seat 311; a lower connecting seat 321 is fixedly connected to the bottom of the lower transmission rack 32, and the lower connecting seat 321 is fixedly connected to the side wall of the connecting frame plate 23 in the lower connecting bracket 202 by bolts, and a lower guide rod 322 arranged vertically upward is fixedly connected to the lower connecting seat 321. The upper guide rod 312 is kept in sliding connection with the lower transmission rack 32, and the lower guide rod 322 is kept in sliding connection with the upper transmission rack 31. In this way, the upper transmission rack 31 and the lower transmission rack 32 are stably assembled on the corresponding connecting frame plate 23, ensuring that the upper transmission rack 31 and the lower transmission rack 32 are stably lifted and lowered in the vertical direction.

[0085] See also Figure 6 , 8 -9. In order to further improve the stability of the assembly and operation of the upper connecting bracket 201 and the lower connecting bracket 202 and ensure that the upper connecting bracket 201 and the lower connecting bracket 202 are not disturbed by gravity during the lifting and lowering movement of the linkage component 3, the following technical solution is provided.

[0086] The linkage assembly 3 also includes an upper pulley 34, a lower pulley 35, a wire rope A36, and a wire rope B37. The upper pulley 34 and the lower pulley 35 are rotatably installed on the top and bottom of the assembly side plate 12, respectively. The upper pulley 34 is arranged above the mounting end plate 24 in the upper connecting bracket 201, and the lower pulley 35 is arranged below the mounting end plate 24 in the lower connecting bracket 202. The wire rope A36 is arranged around the upper pulley 34, and the two ends of the wire rope A36 are respectively fixedly connected to the mounting end plate 24 in the upper connecting bracket 201 and the mounting end plate 24 in the lower connecting bracket 202. The wire rope B37 is arranged around the lower pulley 35, and the two ends of the wire rope B37 are respectively fixedly connected to the mounting end plate 24 in the upper connecting bracket 201 and the mounting end plate 24 in the lower connecting bracket 202.

[0087] An upper cushion seat 124 and a lower cushion seat 125 are fixedly connected to the top and bottom of the outer side wall of the mounting side plate 12, respectively, and an upper pulley 34 and a lower pulley 35 are respectively mounted on the upper cushion seat 124 and the lower cushion seat 125. A transversely arranged wing plate 246 is fixedly connected to the mounting end plate 24 to ensure that the ends of the steel wire rope A36 and the steel wire rope B37 are stably connected to the wing plate 246, and a clearance opening 2461 is opened on the wing plate 246 to ensure that the steel wire rope A36 or the steel wire rope B37 can pass through the wing plate 246 for arrangement.

[0088] The connection method between the wire rope A36, the wire rope B37 and the mounting end plates 24 in the upper connecting bracket 201 and the lower connecting bracket 202 can offset the gravity of the upper connecting bracket 201 and the lower connecting bracket 202, thereby ensuring that the upper connecting bracket 201 and the lower connecting bracket 202 can be stably lifted and lowered in the vertical direction.

[0089] When the driving assembly drives the lower connecting bracket 202 to descend, the upper connecting bracket 201 can be pulled up through the wire rope A36. When the lower connecting bracket 202 moves upward, the upper connecting bracket 201 can be pulled down through the wire rope B37. Example

[0090] See also Figure 5 , 11 , 12. In order to ensure that the driving assembly can be stably installed in the assembly cavity 17 and that the driving assembly can drive the lower connecting bracket 202 to be stably lifted and lowered, the following technical solution is provided.

[0091] Two groups of connecting plates 222 arranged side by side are fixedly connected to the bottom of the reinforcing side plate 22 in the lower connecting bracket 202. A clearance hole B151 is provided on the assembly cover plate 15. The connecting plate 222 passes through the clearance hole B151 and is arranged in the assembly cavity 17. A guide groove 2221 arranged along the horizontal direction is provided at the bottom of the connecting plate 222, and a guide wheel 411 is installed in the guide groove 2221.

[0092] The middle section of the swing arm 41 is rotatably installed in the assembly cavity 17, the top end of the swing arm 41 is rotatably connected to the guide wheel 411, the bottom end of the swing arm 41 is connected to the lifting seat 42 through the connecting rod A45, the lifting seat 42 is slidably installed in the assembly cavity 17 and moves in the vertical direction, the rotating disk 43 is rotatably installed in the assembly cavity 17 and maintains a power connection with the driving motor 44, and the outer edge of the rotating disk 43 is connected to the lifting seat 42 through the connecting rod B46.

[0093] The swing arm 41 is provided with two groups arranged symmetrically, which are respectively matched with the guide grooves 2221 on the two groups of connecting plates 222. A mounting vertical plate 171 is fixedly connected in the assembly cavity 17, and the middle section of the swing arm 41 is rotatably mounted on the mounting vertical plate 171. Two groups of vertically arranged guide columns 172 are fixedly connected on the mounting vertical plate 171. The lifting seat 42 and the guide columns 172 are kept in sliding connection to realize the design requirement of stable movement of the lifting seat 42 in the vertical direction. The two ends of the connecting rod A45 are respectively hinged with the bottom end of the swing arm 41 and the lifting seat 42.

[0094] During the reciprocating lifting and lowering movement of the lifting seat 42 in the vertical direction, the connecting rod A45 can drive the swing arm 41 to swing back and forth, and then the swing arm 41 can drive the connecting plate 222 to lift stably. The guide groove 2221 opened on the swing arm 41 can ensure that the guide wheel 411 at the top of the swing arm 41 can move stably in the horizontal direction therein, thereby eliminating the interference of the horizontal force component on the connecting plate 222 and the lower connecting bracket 202 during the swinging process of the swing arm 41, and avoiding the lower connecting bracket 202 from being subjected to the horizontal force component of the swing arm 41 and causing invalid horizontal displacement to affect the stability of the equipment operation.

[0095] A vertically arranged clearance hole C1711 is opened on the mounting vertical plate 171, and the pin shaft of the lifting seat 42 is arranged in the clearance hole C1711. The two ends of the connecting rod B46 are respectively hinged to the outer edge of the rotating disk 43 and the pin shaft on the lifting seat 42. When the driving motor 44 drives the rotating disk 43 to continuously operate, the lifting seat 42 can be driven to rise and fall stably through the connecting rod B46.

[0096] It should be emphasized that, in the process of the lifting seat 42 being driven to move up and down by the rotating disk 43, the force applied to the lifting seat 42 by the connecting rod B46 has a horizontal component, which will cause the lifting seat 42 to swing left and right in the horizontal direction. If the lifting seat 42 is directly connected to the lower connecting bracket 202, the left and right swinging effect will be transmitted to the lower connecting bracket 202, affecting the stability of the lower connecting bracket 202 in the vertical direction.

[0097] See also Figure 12-14 In order to ensure that the posture adjustment component 5 can be stably installed in the assembly cavity 17 and to ensure that the posture adjustment component 5 is matched with the rotating disk 43 and the driving motor 44, the following technical solution is provided.

[0098] The posture adjustment component 5 includes a locking joint A51, a locking sleeve A52, a locking joint B53, a locking sleeve B54, a sliding plate 55, and an electric telescopic cylinder 56. The locking joint A51 is fixedly connected to the axis of the rotating disk 43, the locking sleeve A52 is fixedly installed on the sliding plate 55 and is locked with the locking joint A51, the locking joint B53 is rotatably installed on the sliding plate 55 and is coaxially arranged with the locking sleeve A52, a spline shaft 531 that runs through the locking sleeve A52 is fixedly connected to the axis of the locking joint B53, the spline shaft 531 is slidably plugged with the rotating disk 43 and the locking joint A51, the locking sleeve B54 is rotatably installed in the assembly cavity 17 and is powered by the driving motor 44, the locking sleeve B54 is locked with the locking joint B53, the sliding plate 55 is slidably installed in the assembly cavity 17, the electric telescopic cylinder 56 is fixedly installed in the assembly cavity 17, and the movable end of the electric telescopic cylinder 56 is fixedly connected to the sliding plate 55.

[0099] In the process of controlling the telescopic movement of the electric telescopic cylinder 56 , the sliding plate 55 and the locking sleeve A52 and the locking joint B53 assembled on the sliding plate 55 can be driven to move synchronously along the axial direction of the rotating disk 43 .

[0100] When the electric telescopic cylinder 56 is in an extended state, the locking joint B53 and the locking sleeve B54 are in a separated state, and the power of the driving motor 44 transmitted by the locking sleeve B54 cannot drive the locking joint B53 to operate, while the locking sleeve A52 and the locking joint A51 are in a locked state. At this time, the rotating disk 43 and its upper locking joint A51 are in a locked state under the action of the locking sleeve A52, thereby making the lifting seat 42, the swing arm 41, the upper connecting bracket 201, and the lower connecting bracket 202 all in a locked state, so as to ensure the stability of each component of the opening assembly in the shutdown state, and facilitate its disassembly and maintenance as well as the access of the warp.

[0101] When the opening assembly is running, the torque and speed output by the turned-on driving motor 44 fluctuate in the initial stage. If the power is directly transmitted to the rotating disk 43, the operation stability of the upper connecting bracket 201 and the lower connecting bracket 202 will be affected.

[0102] After the drive motor 44 becomes stable, when the electric telescopic cylinder 56 is controlled to be in a contracted state, the locking joint B53 and the locking sleeve B54 are in a nested and locked state, and the power of the drive motor 44 can be transmitted to the rotating disk 43 through the locking sleeve B54, the locking joint B53, and the spline shaft 531 to drive the rotating disk 43 to operate stably. In this state, the locking sleeve A52 and the locking joint A51 are in a separated state, and the locking joint A51 operates synchronously with the rotating disk 43 without being interfered by the locking sleeve A52. At this time, the rotating disk 43 can be ensured to be in an unlocked state, and the power of the drive motor 44 can be stably transmitted to the rotating disk 43.

[0103] Two groups of mounting pads 173 arranged side by side are fixedly installed in the assembly cavity 17, the rotating disk 43 and the locking sleeve B54 are respectively rotatably installed on the two groups of mounting pads 173 and maintained in a coaxial arrangement, the guide rod 174 is fixedly connected to the brackets of the two groups of mounting pads 173, and the sliding plate 55 is arranged between the two groups of mounting pads 173 and maintained in a sliding combination with the guide rod 174.

[0104] See also Fig.12 In order to ensure that the power of the driving motor 44 can be stably transmitted to the locking sleeve B54 and to ensure that the driving motor 44 has a sufficiently large torque to drive the rotating disk 43 to operate stably, a worm gear 541 is fixedly connected to the axis of the locking sleeve B54, and a worm 441 is fixedly connected to the output shaft of the driving motor 44, and the worm 441 and the worm gear 541 are in a matching combination.

[0105] The power of the driving motor 44 is transmitted to the locking sleeve B54 through the combination of the worm 441 and the worm wheel 541. The combination of the worm 441 and the worm wheel 541 has the effect of reducing speed and increasing torque, so as to amplify the torque output by the driving motor 44 and thereby drive the locking sleeve B54 to operate stably. When the locking sleeve B54 and the locking head B53 are nested and locked together during the posture adjustment, the rotating disk 43 can be driven to operate stably, thereby driving the upper connecting bracket 201 and the lower connecting bracket 202 to stably lift and lower in the vertical direction.
