Description

Technical Field

[0001] This utility model relates to the field of equipment, specifically to an unwinding assembly for copper wire. Background Technology

[0002] In the processing of copper wire, unwinding is a crucial step in the production process. Traditional unwinding assemblies are typically driven by a motor directly or via gears to rotate the unwinding rollers, and their unwinding speed is usually constant or manually adjusted based on the operator's experience.

[0003] This method has significant drawbacks: when the wire consumption speed changes in subsequent processes, the unwinding speed cannot be adaptively adjusted, which can easily lead to slack accumulation of wire segments between the unwinding roller and the processing equipment, or damage due to excessive tension. Slack wire may become tangled and knotted, forcing the equipment to stop for repairs and severely impacting production efficiency.

[0004] Therefore, there is an urgent need for an unwinding assembly that is simple in structure, can automatically sense the output status of the wire, and intelligently control the start and stop of unwinding accordingly. Utility Model Content

[0005] The purpose of this invention is to provide an unwinding assembly for copper wire. Through the coordinated action of the drive structure, transmission assembly, detection structure and control module, the unwinding process is automatically regulated. The overall structure is ingeniously designed and the transmission is stable. While ensuring the quality of wire feeding, it significantly reduces manual intervention and improves production efficiency and equipment automation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A copper wire unwinding assembly includes a base, an unwinding roller, a drive structure, and a detection structure. The unwinding roller is rotatably mounted on the base. The drive structure is mounted on the base and drives the unwinding roller to rotate via a transmission assembly. The detection structure is located on the wire output path of the unwinding roller. The detection structure includes a support frame, a sliding sleeve that can move up and down on the support frame, and a trigger element located below the support frame. The top of the sliding sleeve is provided with a wire guide element for guiding the wire. The drive structure and the detection structure are electrically connected via a control module. When the wire output is sufficient and the wire output path forms a downward sag, the sliding sleeve slides down and contacts the trigger element. The control module responds to this contact signal and controls the drive structure to pause operation. When the wire output is insufficient and the wire output path is not fully slack, the wire drives the sliding sleeve to move upward and disengage from the trigger element. The control module then controls the drive structure to resume stable operation.

[0007] Compared with existing technologies, the copper wire unwinding assembly using the above-mentioned technical solution has the following advantages: The detection structure can sensitively sense changes in the output wire and trigger a signal through the displacement of the sliding sleeve; the control module then automatically starts and stops the drive structure accordingly, effectively avoiding accumulation and knotting caused by excessive wire slack.

[0008] The system constructs a complete adaptive unwinding system through the coordinated design of the drive structure, transmission components, detection structure, and control module. It can automatically start and stop the unwinding action according to the actual consumption of the wire. In conjunction with the processing equipment in the next process, it effectively prevents the slack accumulation of the wire and improves the stability, continuity, and intelligence level of the unwinding process as a whole.

[0009] Preferably, the support frame includes a base, a support rod vertically fixed on the base, and detection rods spaced parallel to the support rods. The sliding sleeve is slidably fitted onto the detection rods. The support frame employs a combined structure of the base, support rod, and detection rods, providing a stable and precisely guided vertical movement path for the sliding sleeve. This ensures that the sliding sleeve can respond sensitively and accurately to changes in the sag of the wire, thereby guaranteeing the reliability of the detection signal.

[0010] Preferably, a horizontally positioned limiting block connects the top of the support rod and the top of the detection rod. The limiting block effectively prevents the sliding sleeve from detaching from the top of the detection rod when not in operation or due to accidental shaking, enhancing the stability and service life of the detection structure and reducing maintenance requirements.

[0011] Preferably, the sliding sleeve is a tubular structure, and the wire guide is a wire guide ring. The sliding sleeve adopts a tubular structure with a certain length, so that when it is triggered at the lower limit position, it can still support the wire at a certain height above the base, avoiding the contamination or wear that may be caused by the wire directly contacting the ground. The wire guide ring ensures the smooth movement of the wire.

[0012] Preferably, the drive structure is a drive motor mounted on the machine base. The transmission assembly includes a driving pulley, a driven pulley, a belt, a rotating shaft, and a transmission wheel. The driving pulley is located on the output end of the drive motor. The rotating shaft is rotatably mounted on the machine base. The driven pulley is coaxially mounted with the rotating shaft. The driving pulley drives the driven pulley to rotate via the belt. The transmission wheel is mounted on the rotating shaft and makes frictional contact with the unwinding roller to transmit power. The drive motor, in conjunction with the transmission assembly consisting of pulleys, belt, rotating shaft, and transmission wheel, provides a power transmission scheme that is simple in structure, smooth in transmission, and easy to maintain. The friction transmission method can also buffer overload impacts to a certain extent, protecting the drive motor.

[0013] Preferably, the surface or the entire drive wheel is made of rubber. Using rubber significantly increases the friction between the drive wheel and the unwinding roller, ensuring efficient and reliable power transmission. Simultaneously, the rubber material provides cushioning and shock absorption, resulting in lower operating noise.

[0014] Preferably, both ends of the unwinding roller are provided with disc-shaped docking plates, the diameter of which is larger than the diameter of the unwinding roller's cylinder. The number and position of the drive wheels are adapted to the docking plates, and the drive wheels make frictional contact with the outer circumferential surface of the docking plates. The disc-shaped docking plates, with a diameter relatively larger than that of the unwinding roller, not only provide a reliable frictional contact surface for the drive wheels but also limit the axial movement of the coiled wire on the unwinding roller, preventing the wire from becoming tangled and ensuring orderly unwinding.

[0015] Preferably, a limiting ring is provided on the side of the transmission wheel near the end of the shaft and / or on the side of the transmission wheel near the middle of the shaft. The limiting ring is integrally connected to the transmission wheel, and the diameter of the limiting ring exceeds the diameter of the transmission wheel. The integrated setting of the limiting ring can limit the axial position of the transmission wheel on the shaft, preventing it from axially shifting during transmission and losing contact with the mating plate, thus ensuring the stability and continuity of the transmission process.

[0016] Preferably, the machine base is further provided with an auxiliary shaft, an auxiliary wheel, and an auxiliary ring. The auxiliary shaft is rotatably mounted on the machine base and is located on the side of the unwinding roller away from the rotating shaft, and is parallel to the rotating shaft. The auxiliary wheel and the auxiliary ring are both connected to the auxiliary shaft. The dimensions and positions of the auxiliary shaft, auxiliary wheel, and auxiliary ring are adapted to the rotating shaft, drive wheel, and limiting ring, respectively. The auxiliary support structure composed of the auxiliary shaft, auxiliary wheel, and auxiliary ring can provide auxiliary drive or stable support from the other side of the unwinding roller, working in conjunction with the main drive side to further enhance the smoothness and reliability of driving the unwinding roller to rotate, and is especially suitable for large or heavy coils.

[0017] Preferably, the control module integrates a control program and an audible and visual alarm. By executing a preset control program, the control module controls the drive structure to pause and activate the audible and visual alarm when the trigger is activated, and controls the drive structure to operate stably when the trigger is not activated. The integration of the control program and the audible and visual alarm enables automatic conversion of detection signals into action and real-time human-machine interaction, allowing the equipment to operate automatically without human intervention. In abnormal situations (such as when the equipment is paused due to insufficient cable), the audible and visual signals promptly notify the operator, improving the automation level and safety of the equipment.

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] like Figures 1 to 4 The copper wire unwinding assembly shown includes a base 1, an unwinding roller 2, a drive structure, and a detection structure.

[0025] The unwinding roller 2 is rotatably mounted on the machine base 1, and the drive structure is mounted on the machine base 1 and drives the unwinding roller 2 to rotate through the transmission assembly 3.

[0026] Regarding the drive structure and transmission assembly 3, the drive structure is a drive motor 8 mounted on the base 1, and the transmission assembly 3 includes a driving pulley 30, a driven pulley 31, a belt 32, a rotating shaft 33, and a transmission wheel 34.

[0027] The drive pulley 30 is located on the output end of the drive motor 8, the rotating shaft 33 is rotatably mounted on the machine base 1, the driven pulley 31 is coaxially mounted with the rotating shaft 33, the drive pulley 30 drives the driven pulley 31 to rotate via the belt 32, and the transmission wheel 34 is mounted on the rotating shaft 33, and the transmission wheel 34 is in frictional contact with the unwinding roller 2 to transmit power.

[0028] To fully realize the transmission effect, the surface of the transmission wheel 34 can be made of rubber, or the entire transmission wheel 34 can be made of rubber. In this embodiment, the entire transmission wheel 34 is made of rubber.

[0029] Considering the limiting requirements for the wire 0 on the unwinding roller 2 and the structural proportions of the transmission assembly 3, the unwinding roller 2, and the winding state of the wire 0, in order to ensure smooth operation and functional realization of the equipment, both ends of the unwinding roller 2 are provided with disc-shaped docking plates 20. The diameter of the docking plates 20 is larger than the diameter of the cylinder of the unwinding roller 2. The number and setting position of the transmission wheels 34 are adapted to the docking plates 20, and the transmission wheels 34 are in frictional contact with the outer peripheral surface of the docking plates 20.

[0030] In order to increase the stable transmission effect between the transmission assembly 3 and the docking plate 20, a limiting ring 35 is provided on the side of the transmission wheel 34 near the end of the rotating shaft 33 and / or on the side of the transmission wheel 34 near the middle of the rotating shaft 33. The limiting ring 35 is integrally connected with the transmission wheel 34, and the diameter of the limiting ring 35 exceeds the diameter of the transmission wheel 34.

[0031] To avoid insufficient transmission force, this design can adopt a scheme with dual drive motors 8 and dual transmission components 3, or an additional auxiliary structure to drive the unwinding roller 2 to rotate simultaneously.

[0032] In this embodiment, an additional auxiliary structure is selected, namely, the machine base 1 is also provided with an auxiliary shaft 9, an auxiliary wheel 90 and an auxiliary ring 91. The auxiliary shaft 9 is rotatably mounted on the machine base 1 and is located on the side of the unwinding roller 2 away from the rotating shaft 33. The auxiliary shaft 9 is parallel to the rotating shaft 33. The auxiliary wheel 90 and the auxiliary ring 91 are both connected to the auxiliary shaft 9. The size and position of the auxiliary shaft 9, the auxiliary wheel 90 and the auxiliary ring 91 are adapted to the rotating shaft 33, the transmission wheel 34 and the limiting ring 35, respectively.

[0033] It should be noted that this additional auxiliary rotation scheme can also be supplemented with a dedicated drive motor 8 to further enhance the control effect on the unwinding roller 2.

[0034] The detection structure is located on the wire output path of the unwinding roller 2. The detection structure includes a support frame 4, a sliding sleeve 5 that can move up and down on the support frame 4, and a trigger 6 located below the support frame 4. The top of the sliding sleeve 5 has a wire guide for guiding the wire. The drive structure and the detection structure are electrically connected via a control module 7. When the wire output is sufficient and the wire output path forms a downward sag, the sliding sleeve 5 slides down and contacts the trigger 6. The control module 7 responds to this contact signal and controls the drive structure to pause operation. When the wire output is insufficient and the wire output path is not fully slack, the wire drives the sliding sleeve 5 upward and disengages from the trigger 6. The control module 7 then controls the drive structure to resume stable operation.

[0035] Regarding the control module 7, the control module 7 integrates a control program and an audible and visual alarm 70. The control module 7 executes a preset control program. The trigger 6 can refer to an existing micro switch. The audible and visual alarm 70 includes an audible alarm (speaker, buzzer, or voice prompt) and a visual alarm (LED beads). When the trigger 6 is triggered, the control drive structure is paused and the audible and visual alarm is activated. When the trigger 6 is not triggered, the control drive structure operates stably.

[0036] Taking into account the vertical displacement of the sliding sleeve 5 and the placement requirements of the support frame 4 itself, the support frame 4 includes a base 40, a support rod 41 vertically fixed on the base 40, and a detection rod 42 parallel to and spaced apart from the support rod 41. The sliding sleeve 5 is mounted on the detection rod 42.

[0037] Furthermore, to prevent the sliding sleeve 5 from displacing excessively and detaching from the detection rod 42, a horizontally positioned limiting block 43 is connected between the top of the support rod 41 and the detection rod 42.

[0038] In addition, to avoid the problem that the output cable 0 is triggered only when it is completely submerged, this embodiment limits the triggering distance of the sliding sleeve 5. That is, the sliding sleeve 5 is a tubular structure with a certain length (there is a sufficient distance between the upper end of the sliding sleeve 5 and the lower end of the sliding sleeve 5), and the cable 0 guide is the cable guide ring 50.

[0039] During operation, the unwinding roller 2 is pre-loaded with coiled copper wire 0. First, the end of the wire 0 passes through the wire guide ring 50 of the detection structure and is led to the next processing equipment. The specific operation process is as follows: The equipment is started, and the drive motor 8 drives the rotating shaft 33 to rotate via the active pulley 30, belt 32, and driven pulley 31. The transmission wheel 34 on the rotating shaft 33 drives the unwinding roller 2 to rotate and unwind through frictional contact with the end contact plate 20 of the unwinding roller 2. During unwinding, the wire 0 forms an output path between the unwinding roller 2 and the subsequent equipment. When the subsequent equipment consumes less and has sufficient wire 0, the output path of the wire 0 droops and its curvature increases. The sliding sleeve 5 gradually slides down along the detection rod 42 until it reaches the bottom and contacts the trigger 6. At this time, the trigger 6 sends a signal to the control module 7, which then executes a preset program, commanding the drive motor 8 to stop operating and activating an audible and visual alarm to alert the operator. As the subsequent equipment consumes wire 0 and the suspension section gradually tightens, wire 0 pulls the sliding sleeve 5 upward, causing it to disengage from the trigger 6. The control module 7 then responds again, immediately restoring the stable operation of the drive motor 8 and continuing unwinding. This cycle repeats, achieving automatic control of the unwinding process.

[0040] The above description is a preferred embodiment of the present utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered within the protection scope of the present utility model.
