Description

Technical Field

[0001] The invention relates to the technical field of wire twisting devices, in particular to an adjustable tension device for high-speed wire twisting. Background Art

[0002] In the Chinese patent with the patent publication number CN217035262U, a steel structure installation omnidirectional automatic alignment mechanism is disclosed, including a support frame, a support plate is slidably mounted on the support frame, the cross-sections of the support frame and the support plate along the length direction are both U-shaped, a support table is fixedly mounted on the top of the support plate, a PLC controller is fixedly mounted on the side wall surface of the support table, the support table is arranged in a stepped shape, a speed regulating roller is rotatably mounted on the bottom step of the support table, a tension regulating mechanism matching the speed regulating roller is arranged on the support table, and a limit roller is rotatably mounted on the bottom step of the support table. The utility model has a novel structure, which not only improves the maintenance efficiency, but also improves the applicability, and is suitable for promotion.

[0003] However, the following defects still exist in the specific use of the comparative documents:

[0004] 1. Although the comparative document can perform simple tension control, the continuous operation of the machine will inevitably attract dust and tiny impurities in the air. These substances will gradually adhere to the surface of the wire harness to form a granular covering. This phenomenon is particularly prominent in the high-intensity environment of tension adjustment and twisting operations. These granular attachments may not only wear the outer protective layer of the wire harness, but also directly damage the conductor or insulation layer inside the wire harness in more serious cases, resulting in obvious dents or even breaks on the surface of the wire harness. This type of physical damage not only reduces the overall quality of the wire harness, but may also cause safety hazards in subsequent use, adversely affecting the overall production process, and increasing the defective rate and production costs.

[0005] 2. The comparative document uses rollers to control the tension of the wire harness. When the wire harness is suddenly broken during the twisting process due to quality problems of the wire harness itself (such as insufficient strength, internal defects, etc.) or external factors (such as improper operation, machine failure, etc.), the system only relies on rollers for a single tension adjustment and lacks sufficient emergency response mechanism. Therefore, at the moment the wire harness breaks, the wire harness may deviate from the original path and splash everywhere, which will not only cause production interruption, but also may cause impact or damage to surrounding equipment, increasing uncertainty and risk in the production process.

[0006] Therefore, an adjustable tension device for high-speed stranded wire is proposed to solve the above problems. Summary of the invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose an adjustable tension device for high-speed twisted wire to solve the problems in the prior art that the wire harness cannot achieve self-cleaning when the tension is automatically adjusted and the wire harness is not provided with wire harness breakage protection.

[0008] To achieve the above object, the present invention provides the following technical solutions: an adjustable tension device for high-speed stranded wire, comprising an operating table, an adjusting frame slidably connected to the operating table, a stranded wire drum mounted on the adjusting frame, a dust collector disposed on one side of the stranded wire drum, a tension adjusting mechanism and an adjustable protective mechanism, the tension adjusting mechanism being disposed on the stranded wire drum, and the adjustable protective mechanism being disposed above the adjusting frame;

[0009] The tension adjustment mechanism is used for dust removal and tension adjustment during wire harness twisting;

[0010] The adjustable protection mechanism is used for preventing the wire harness from breaking when the wires are twisted in one direction.

[0011] Preferably, the tension adjustment mechanism includes a driving gear disc, which is rotatably connected to the middle part of the capstan, and the tooth surface of the driving gear disc is meshed with an engaging disc, and the middle part of the engaging disc is slidably connected with a threaded limiting slide, and the threaded limiting slide is threadedly connected to the capstan at one end close to the capstan, and the inner surface of the threaded limiting slide is rotatably connected to a bevel extrusion ring, and the bevel extrusion ring is provided with a bevel on the side away from the threaded limiting slide.

[0012] Preferably, a trapezoidal extrusion block is arranged on the side of the inclined extrusion ring away from the threaded limiting slide cylinder, a sliding shaft is fixedly connected to the non-inclined end in the middle of the trapezoidal extrusion block, a driving sleeve is rotatably connected to the middle of the winding drum, a sliding hole is opened on the circumference of the driving sleeve, and the outer surface of the sliding shaft is slidably connected to the sliding hole opened in the driving sleeve.

[0013] Preferably, an auxiliary spring is sleeved on the outer surface of one end of the sliding shaft close to the trapezoidal extrusion block, one end of the auxiliary spring is fixedly connected to the driving sleeve, the other end of the auxiliary spring is fixedly connected to the trapezoidal extrusion block, and the end of the sliding shaft away from the trapezoidal extrusion block is rotatably connected to a rubber extrusion shaft.

[0014] Preferably, a linkage cleaning mechanism is provided on the side of the wire drum close to the tension adjustment mechanism, and the linkage cleaning mechanism includes a wire harness rod, a multifunctional reel is slidably connected to the lower outer surface of the wire harness rod, both ends of the multifunctional reel are rotatably connected to fixed blocks, the fixed block is fixedly connected to a multifunctional bracket, and the multifunctional bracket is fixedly connected to the wire drum.

[0015] Preferably, one circumference of the multifunctional reel is provided with bevel teeth, the tooth surface of the multifunctional reel is meshed with a meshing gear cylinder, and the meshing gear cylinder is fixedly connected to the driving sleeve at one end away from the multifunctional reel.

[0016] Preferably, the adjustable protective mechanism includes a dust collecting chamber, one end of the dust collecting chamber is fixedly connected to the wire drum, the other end of the dust collecting chamber is fixedly connected to the vacuum cleaner, and a one-way limit plate is rotatably connected to the multifunctional bracket, and a buffer spring is fixedly connected to the one-way limit plate.

[0017] Preferably, the buffer spring is fixedly connected to the multifunctional bracket at one end away from the one-way limit plate, and the one-way limit plate is provided with a sliding groove at one end close to the wiring harness rod, and the wiring harness rod slides in the sliding groove of the one-way limit plate.

[0018] Compared with the prior art, the adjustable tension device for high-speed stranded wire provided by the present invention has the following beneficial effects:

[0019] 1. Through the setting of the threaded limit slide and the rubber extrusion shaft, the rotation of the drive gear disc component is driven by the motor, and the precise meshing of the drive gear disc and the meshing disc is used to further drive the threaded limit slide component to move, and drive the trapezoidal extrusion block component to apply pressure to the slide shaft.

[0020] 2. Compared with the roller-type tension control commonly used in the prior art, the rubber extrusion shaft component of the present invention not only bears the heavy task of tension adjustment, but also cleverly integrates the dust handling function. Through the linkage of the driving sleeve and the meshing gear cylinder component, the rubber extrusion shaft can effectively clean the dust on the surface of the harness rod while adjusting the tension. This design of the present invention not only extends the service life of the equipment, but also significantly improves the production quality of the product.

[0021] 3. In order to prevent the dust generated during the cleaning process from diffusing into the air again and adhering to the wiring harness rod, the present invention also carefully designs a dust sealing and collection system, wherein the dust chamber component, as one of the key components, is responsible for effectively sealing the dust in a specific area; and the vacuum cleaner component is responsible for collecting and processing the remaining dust that has been cleaned up to ensure the cleanliness and hygiene of the production environment.

[0022] 4. The configuration of the present invention can effectively mitigate and control the potential risk of breakage of the wire harness due to tension or cracks during transportation. When the wire harness is subjected to abnormal stress and is about to break, the reverse protection locking device can respond quickly. Through its unique locking mechanism, the copper rod is firmly locked on the transmission path, thereby avoiding the sudden collapse of the copper rod and impacting the surrounding equipment, especially the winding wheel, causing its structure to loosen, further reducing the chaos and safety hazards at the production site.

[0043] A trapezoidal extrusion block 29 is arranged on the side of the inclined extrusion ring 24 away from the threaded limiting slide cylinder 23, a sliding shaft 25 is fixedly connected to the non-inclined end in the middle of the trapezoidal extrusion block 29, a driving sleeve 28 is rotatably connected to the middle of the capstan 12, a sliding hole is opened on the circumference of the driving sleeve 28, and the outer surface of the sliding shaft 25 is slidably connected to the sliding hole opened in the driving sleeve 28;

[0044] An auxiliary spring 26 is sleeved on the outer surface of one end of the sliding shaft 25 close to the trapezoidal extrusion block 29, one end of the auxiliary spring 26 is fixedly connected to the driving sleeve 28, and the other end of the auxiliary spring 26 is fixedly connected to the trapezoidal extrusion block 29. The end of the sliding shaft 25 away from the trapezoidal extrusion block 29 is rotatably connected to the rubber extrusion shaft 27;

[0045] A linkage cleaning mechanism 3 is provided on one side of the winding drum 12 close to the tension adjustment mechanism 2. The linkage cleaning mechanism 3 includes a harness rod 31. A multifunctional reel 32 is slidably connected to the lower portion of the outer surface of the harness rod 31. Both ends of the multifunctional reel 32 are rotatably connected to fixed blocks 33. The fixed block 33 is fixedly connected to a multifunctional bracket 42. The multifunctional bracket 42 is fixedly connected to the winding drum 12.

[0046] A beveled tooth is arranged on one circumference of the multifunctional reel 32, and a meshing gear cylinder 34 is meshed on the tooth surface of the multifunctional reel 32. The meshing gear cylinder 34 is fixedly connected to the driving sleeve 28 at one end away from the multifunctional reel 32.

[0047] Wherein: a motor is installed in the middle of the stranding drum 12, and the motor driving shaft is fixedly connected to the middle of the driving gear disc 21.

[0048] Compared with the reference document, through the implementation of this embodiment, the threaded limit slide 23 and the rubber extrusion shaft 27 are set, the rotation of the gear disc 21 is driven by the motor, and the precise meshing of the driving gear disc 21 and the meshing disc 22 is utilized to further drive the threaded limit slide 23 to move, and drive the trapezoidal extrusion block 29 to apply pressure to the slide shaft 25.

[0049] For further examples, please refer to Figures 1 to 7 As shown:

[0050] The adjustable protection mechanism 4 includes a dust collecting chamber 41, one end of the dust collecting chamber 41 is fixedly connected to the winding drum 12, and the other end of the dust collecting chamber 41 is fixedly connected to the dust collector 13, a one-way limit plate 43 is rotatably connected to the multifunctional bracket 42, and a buffer spring 44 is fixedly connected to the one-way limit plate 43;

[0052] Wherein: a sliding groove is provided at one end of the one-way limiting piece 43 close to the harness rod 31, and the harness rod 31 slides in the sliding groove provided in the one-way limiting piece 43;

[0053] Compared with the comparative documents, through the implementation of this embodiment, the setting of the present invention can effectively mitigate and control the potential risk of breakage of the wire harness due to tension or cracks during transportation. When the wire harness is subjected to abnormal stress and is about to break, the reverse protection locking device can respond quickly. Through its unique locking mechanism, the copper rod is firmly locked on the transmission path, thereby avoiding the sudden collapse of the copper rod and impacting the surrounding equipment, especially the winding wheel, causing its structure to loosen, further reducing the chaos and safety hazards at the production site.

[0054] Everything in the above example works like this:

[0055] In the initial state: the motor is not started, and the harness rod 31 passes through the winding drum 12 and the middle of the dust collecting chamber 41.

[0056] The following is the working process of the tension adjustment mechanism 2 for dust removal and tension adjustment during the wire harness twisting and the adjustable protection mechanism 4 for automatic protection:

[0057] When using, Figure 1 As shown in the figure, the wire harness is prepared for stranding from the right to the left. At this time, when the wire harness is pulled by the stranding equipment, Figure 7 As shown, at this time, the sliding of the harness rod 31 to the left will drive the multifunctional reel 32 to start sliding synchronously, because the extrusion effect of the harness rod 31 in the twisting direction will drive the multifunctional reel 32 to start rotating counterclockwise. At this time, because the outer surface of one side of the multifunctional reel 32 is circumferentially provided with sliding teeth, and the sliding teeth are meshed with the tooth surface of the meshing gear cylinder 34, when the multifunctional reel 32 rotates counterclockwise, the meshing gear cylinder 34 will start rotating counterclockwise in the same direction. At this time, because the meshing gear cylinder 34 is fixedly connected to the middle part of the driving sleeve 28, the counterclockwise rotation of the meshing gear cylinder 34 will drive the driving sleeve 28 to start rotating in the same direction.

[0058] at this time Figure 5 As shown, because the middle of the driving sleeve 28 is evenly provided with sliding holes, and the sliding shaft 25 is slidably connected in the sliding holes, and because one end of the sliding shaft 25 is rotatably connected to the rubber extrusion shaft 27, and the other end is fixedly connected to the trapezoidal extrusion block 29, the sliding shaft 25 is driven by the driving sleeve 28 to rotate in the counterclockwise direction to drive the rubber extrusion shaft 27 to start rotating in the middle of the winch drum 12, and because the rubber extrusion shaft 27 is circumferentially arranged in the threaded limiting sliding cylinder 23, and the harness rod 31 passes through the middle of the driving sleeve 28, the rubber extrusion shaft 27 is driven to clean the surface of the harness rod 31 when the multi-functional reel 32 rotates.

[0059] At the same time, the wire harness rod 31 of different sizes is conveniently adjusted for twisting. In the present invention, a motor is fixedly connected to the middle of the driving toothed disc 21, and the motor is started to rotate under the control of the controller. The rotation of the motor drives the driving toothed disc 21 to start synchronous rotation. Since the tooth surface of the driving toothed disc 21 and the meshing disc 22 are meshed with each other, the rotation of the driving toothed disc 21 drives the meshing disc 22 to start rotating in the opposite direction. Figure 5 As shown, since the threaded limit slide 23 is slidably connected in the meshing disk 22, and since the threaded limit slide 23 is threadedly connected in the winding disk 12, the threaded limit slide 23 is driven to rotate by the meshing disk 22, which will cause the threaded limit slide 23 to start to move in the horizontal direction. Since the inclined surface extrusion ring 24 is rotatably connected to the inner wall of the threaded limit slide 23, and the inclined surface extrusion ring 24 is provided with an inclined surface on the side away from the threaded limit slide 23, the inclined surface extrusion ring 24 is inclined to the trapezoidal extrusion block 29. The extrusion of the inclined surface will drive the trapezoidal extrusion block 29 to drive the slide shaft 25 to slide in the slide hole opened by the drive sleeve 28. At this time, the sliding of the slide shaft 25 will drive the rubber extrusion shaft 27 to adjust. Through the setting of the threaded limit slide 23 and the rubber extrusion shaft 27, the rotation of the toothed disc 21 is driven by the motor, and the precise meshing of the drive toothed disc 21 and the meshing disc 22 is utilized to further drive the threaded limit slide 23 to move, and drive the trapezoidal extrusion block 29 to apply pressure to the slide shaft 25. This series of mechanical actions ingeniously realizes the precise adjustment of the rubber extrusion shaft 27, thereby changing the contact distance between the rubber extrusion shaft 27 and the surface of the harness rod 31. The adjustment of this contact distance is directly related to the tension generated when the harness rod 31 slides on the rubber extrusion shaft 27, providing users with more flexible and precise tension control options.

[0060] Compared with the roller-type tension control commonly used in the prior art, the rubber extrusion shaft 27 component of the present invention not only bears the important task of tension adjustment, but also cleverly integrates the dust handling function. Through the linkage action of the driving sleeve 28 and the meshing gear cylinder 34 components, the rubber extrusion shaft 27 can effectively clean the dust on the surface of the harness rod 31 while adjusting the tension. This design of the present invention not only extends the service life of the equipment, but also significantly improves the production quality of the product.

[0061] In order to prevent the dust generated during the cleaning process from diffusing into the air again and adhering to the wiring harness rod 31, the present invention also carefully designs a dust sealing and collection system, wherein the dust chamber 41 component is one of the key components, responsible for effectively sealing the dust in a specific area; and the vacuum cleaner 13 component is responsible for collecting and processing the remaining dust that has been cleaned up to ensure the cleanliness and hygiene of the production environment.

[0062] And if Figure 6As shown, because the multifunctional bracket 42 is circumferentially fixedly connected to the winding drum 12, and the wiring harness rod 31 is slidably connected to the slide groove starting from the one-way limit plate 43, the sliding of the wiring harness rod 31 to the left will drive the one-way limit plate 43 to squeeze the buffer spring 44, and the buffer spring 44 begins to be compressed. When the wiring harness rod 31 breaks due to its own quality or other reasons, the setting of the present invention can effectively reduce and control the potential risk of breaking of the wiring harness due to tension or cracks during transportation. When the wiring harness is subjected to abnormal stress and is about to break, the reverse protection locking device can respond quickly, and through its unique locking mechanism, the copper rod is firmly locked on the transmission path, thereby avoiding the sudden collapse of the copper rod and impacting the surrounding equipment, especially the winding wheel, resulting in a loose structure, further reducing chaos and safety hazards at the production site.
