Description

Technical Field

[0001] This utility model relates to the technical field of wire processing equipment, specifically a wire feeding device for wire processing. Background Technology

[0002] In the wire processing and production process, the wire unwinding device is one of the key pieces of equipment to ensure processing continuity and product quality. Its main function is to smoothly and orderly release the coiled strip wire, providing a stable supply of wire for subsequent processes such as cutting, crimping, and insulation treatment. Due to the inherent structural characteristics of strip wire, the unwinding process requires high standards for tension control, unwinding speed stability, and start-stop safety. Once fluctuations occur during the unwinding process or improper start-stop control occurs, it can easily lead to wire stretching deformation, surface scratches, or even breakage, directly affecting processing efficiency and product qualification rate.

[0003] However, existing wire-laying devices for wire processing generally have certain defects, the core problem being the lack of a specific functional design for safe wire-laying stop and start.

[0004] In actual production operations, when encountering equipment failure, process switching, or emergency situations requiring a sudden stop of wire feeding, the existing device cannot achieve rapid and gentle braking of the strip wire. Under the action of inertia, the wire will continue to be conveyed forward for a certain distance. This excess wire is prone to friction and squeezing with equipment parts, resulting in damage to the wire surface and deformation of the internal conductor. Meanwhile, the sudden change in tension caused by inertia may also cause the wire to break due to stretching, which not only increases the loss of raw materials, but also interrupts the production process and reduces processing efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wire feeding device for wire processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A wire feeding device for wire processing, characterized in that it comprises: a base, a working plate fixedly mounted on the base by multiple sets of support plates, a first wheel and a second wheel fixedly mounted on the right side of the working plate by rotating shafts respectively, a motor fixedly mounted at the bottom center of the rotating shaft of the first wheel, a servo motor fixedly mounted at the bottom center of the rotating shaft of the second wheel, a feeding assembly mounted on the left side of the second wheel, a strip wire arranged around the feeding assembly, the first wheel and the second wheel, the motor being used to start and feed the strip wire on the second wheel outward, the servo motor being used to start and wind the strip wire, and the feeding assembly being used to control the winding and feeding of the strip wire; The wire feeding assembly includes two rollers: Roller 1 and Roller 2, which are symmetrically arranged on the left and right. A limit seat is set on the right side of Roller 1. The bottom of the limit seat is fixed to the work plate by bolts. Rollers are symmetrically arranged on the left and right sides of the limit seat. The strip wire passes through the two rollers. An electric cylinder is fixedly set below the limit seat. A clamping claw is fixedly set on the moving block symmetrically arranged on the left side of the electric cylinder by bolts. The electric cylinder is used to start the moving blocks to move closer to each other, driving the clamping claw to clamp the strip wire. At this time, the wire feeding stops. The strip wire on the second roller will extend through Roller 1 under the action of inertia, and then be tightened again in the opposite direction under the action of the servo motor.

[0007] Preferably, a limiting block is provided on the strip wire between the second roller and the second disc. The limiting block has a through hole for the strip wire to pass through. An elastic buffer layer is provided on the inner wall of the through hole, and elastic pads are provided on the opposite inner side of the clamping claw.

[0008] Limiting blocks are used to radially limit and buffer the protection of strip wires during the wire laying or winding process.

[0009] Preferably, both the first and second wheel disks are provided with annular slots on their circumferential surfaces, and the end of the strip wire is fixedly locked in the annular slot of the second wheel disk.

[0010] Preferably, a tension sensor is also provided on the working plate in the area between the wire feeding assembly and the second reel. The tension sensor is electrically connected to the servo motor and is used to detect the tension of the strip wire in real time and provide feedback to control the winding speed of the servo motor.

[0011] Preferably, the surfaces of roller one and roller two are covered with spiral guide grooves, which are used to increase the friction with the strip wire and provide guidance.

[0012] Preferably, the electric cylinder is connected to the control system. The control system is used to control the electric cylinder to drive the clamping jaws to clamp the strip wire when it is necessary to stop the unwinding, and to control the servo motor to start the reverse winding after a predetermined delay.

[0013] Compared with the prior art, the present invention provides a wire feeding device for wire processing, which has the following advantages: The symmetrical arrangement of rollers one and two in the wire feeding assembly, along with the spiral guide grooves covering their surfaces, not only provides precise guidance for the strip wire, ensuring that the wire moves along a preset trajectory during feeding and winding, avoiding problems such as deviation and tangling, but also increases the friction with the wire surface through the spiral guide grooves, improving the stability of the feeding process. The limiting seat on the right side of roller one and the symmetrically arranged rollers form a secondary guiding and limiting structure. As the strip wire passes between the two rollers, the radial swing of the wire can be further restricted, reducing swaying during the feeding process and providing stable conditions for subsequent clamping and braking.

[0014] The electric cylinder and clamping claws located below the limit seat constitute the core safety start-stop mechanism. The linkage design between the electric cylinder and the control system allows for rapid driving of symmetrically arranged moving blocks to approach each other when it is necessary to stop wire feeding. This causes the clamping claws to precisely grip the strip wire, achieving rapid braking during the feeding process. Simultaneously, elastic pads on the inner sides of the clamping claws effectively buffer the clamping force, preventing damage to the wire surface and protecting the wire. To address the issue of wire elongation due to inertia after a sudden stop, the control system delays and reverses the servo motor to re-tighten excess wire, preventing tangling or damage caused by wire slack and ensuring the continuity and safety of the feeding process.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-4 As shown, a wire feeding device for wire processing in this embodiment includes a base 1. The base 1 serves as the supporting foundation for the entire device, and its stable structural design provides stable support for the installation of each component. A working plate 101 is fixedly mounted on the base 1 by multiple sets of support plates. The distribution of the multiple sets of support plates ensures the flatness and firmness of the working plate 101 during installation, and avoids deformation of the working plate 101 due to vibration during operation.

[0019] On the right side of the work plate 101, a first wheel 201 and a second wheel 202 are fixedly mounted at the front and rear via rotating shafts, respectively. The fixed connection between the rotating shafts and the work plate 101 ensures the stability of the rotation of the first wheel 201 and the second wheel 202. A motor 2011 is fixedly mounted at the bottom center of the rotating shaft of the first wheel 201, which provides power output for the wire feeding process. A servo motor 2021 is fixedly mounted at the bottom center of the rotating shaft of the second wheel 202, which is used to realize the winding action of the strip wire 4. The two work together to achieve dynamic balance between wire feeding and winding.

[0020] A wire feeding assembly 3 is provided on the left side of the second reel 202. A strip wire 4 is arranged around the wire feeding assembly 3, the first reel 201, and the second reel 202. Both the first reel 201 and the second reel 202 have annular slots. The end of the strip wire 4 is fixedly locked in the annular slot of the second reel 202. The annular slot can limit the strip wire 4 and prevent the wire from falling off during the wire feeding and winding process.

[0021] The wire feeding assembly 3 includes a first roller 301 and a second roller 304, which are symmetrically arranged on the left and right sides. Both rollers have spiral guide grooves on their surfaces to increase friction and guide the strip wire 4. A limit seat 302 is provided on the right side of the first roller 301. The bottom of the limit seat 302 is fixed to the working plate 101 by bolts. The bolt connection facilitates subsequent disassembly and maintenance. Rollers 3021 are symmetrically arranged on the left and right sides of the limit seat 302. The strip wire 4 passes through the rollers 3021 on both sides to form a precise guide and limit.

[0022] An electric cylinder 306 is fixedly installed below the limiting seat 302. A clamping claw 307 is bolted to a movable block symmetrically arranged on the left side of the electric cylinder 306. Elastic washers are provided on the inner sides of the clamping claws 307 to prevent damage to the wire during clamping. The electric cylinder 306 is connected to a control system. The control system is used to control the electric cylinder 306 to drive the clamping claws 307 to clamp the strip wire 4 when it is necessary to stop unwinding, and then controls the servo motor 2021 to start rewinding in the reverse direction after a predetermined delay.

[0023] A limiting block 305 is installed on the strip wire between the second roller 304 and the second wheel 202. The limiting block 305 has a through hole for the strip wire 4 to pass through, and the inner wall of the through hole is provided with an elastic buffer layer. The limiting block 305 is used to radially limit and buffer the strip wire 4 during the wire feeding or winding process. A tension sensor is also installed on the working plate 101 in the area between the wire feeding assembly 3 and the second wheel 202. The tension sensor is electrically connected to the servo motor 2021. The tension sensor is used to detect the tension of the strip wire 4 in real time and provide feedback to control the winding speed of the servo motor 2021.

[0024] The working principle of this utility model is as follows: When using this wire processing wire feeding device, the first step is to install and debug the device. Select a flat installation site according to the processing requirements, and place the base 1 stably, ensuring the entire device is level. Secure the work plate 101 onto the base 1 using multiple support plates, checking the stability of the work plate 101 to prevent loosening. Then, fix wheel one 201 and wheel two 202 to the front and rear positions on the right side of the work plate 101 respectively via rotating shafts. Fix motor 2011 to the bottom center of the rotating shaft of wheel one 201, and servo motor 2021 to the bottom center of the rotating shaft of wheel two 202, and connect their power lines.

[0025] Next, install the wire feeding assembly 3: symmetrically fix roller 1 301 and roller 2 304 on the working plate 101, ensuring that their spiral guide grooves are aligned; fix the limit seat 302 to the working plate 101 on the right side of roller 1 301 with bolts, and symmetrically install roller shafts 3021 on the left and right sides of the limit seat 302; fix the electric cylinder 306 on the working plate 101 below the limit seat 302, and install the clamping claw 307 on the symmetrical moving block on the left side of the electric cylinder 306 with bolts, ensuring that the clamping surfaces of the clamping claw 307 are aligned; install the limit block 305 on the working plate 101 between roller 2 304 and wheel 2 202, so that the preset path of the strip wire 4 passes through the through hole of the limit block 305; finally, install the tension sensor on the working plate 101 between the wire feeding assembly 3 and wheel 2 202, and complete the electrical connection between the tension sensor and the servo motor 2021, and between the electric cylinder and the control system. The end of the strip wire 4 is fixedly clamped in the annular groove of the second wheel 202, and then passes through the roller 2 304, the limiting block 305, the first roller 301, the two roller shafts 3021 of the limiting seat 302, and the first wheel 201 in sequence to complete the winding arrangement of the wire. After debugging and confirming that the operation of each component is coordinated, the device can be started for operation.

[0026] During normal operation, motor 2011 is started, which drives the first roller 201 to rotate, feeding the strip wire 4 from the second roller 202 outwards. Simultaneously, servo motor 2021 starts to perform a winding action, and the two work together to achieve a stable feeding speed. During this process, the first roller 301 and the second roller 304 of the feeding assembly 3 guide the strip wire 4 through the spiral guide grooves on their surfaces to prevent the wire from deviating. The roller 3021 of the limit seat 302 further restricts the radial swing of the wire. The tension sensor detects the tension of the strip wire 4 in real time and feeds the detection data back to the control system. The control system adjusts the winding speed of the servo motor 2021 according to the preset tension threshold to ensure that the feeding tension remains stable at all times.

[0027] When encountering process changes, equipment malfunctions, or other emergencies requiring a halt to wire feeding, the operator issues a stop command through the control system. The control system immediately activates the electric cylinder 306, which drives the symmetrical moving blocks on the left to move closer together, causing the clamping claws 307 to clamp and brake the strip wire 4, achieving a rapid stop in the wire feeding process. Because the clamping claws 307 have elastic pads on their inner sides, excessive clamping force can effectively prevent damage to the wire surface. At this time, the strip wire 4 on the second wheel 202 will continue to extend beyond the first roller 301 due to inertia. After a predetermined delay, the control system controls the servo motor 2021 to start in reverse, re-tightening the excess extended strip wire 4 to prevent wire slack and accumulation.

[0028] After the operation is completed, turn off motor 2011 and servo motor 2021, release the clamping jaws 307, and remove the processed strip wire 4 from the wheel 202. The entire device, through the coordinated action of the wire feeding assembly 3, achieves safe start-stop and stable control of the wire feeding process, effectively solving the problem of wire damage caused by sudden stops in existing devices, and improving processing quality and efficiency.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
