Description

Technical Field

[0001] This utility model relates to the technical field of core wire processing equipment, specifically to an automatically adjustable core wire sheathing device. Background Technology

[0002] In fields such as wire and cable production and electrical equipment assembly, it is often necessary to break the insulation of the core wire to expose the internal conductor, which facilitates subsequent connection, welding and other operations.

[0003] Most wire stripping equipment on the market is designed with fixed specifications, meaning it can only strip wires of a specific diameter and insulation thickness. When processing wires of different specifications, operators need to manually change the stripping blades, adjust the blade spacing, or replace the entire stripping module. This operation is cumbersome and time-consuming, seriously affecting production efficiency. At the same time, during manual adjustment, it is difficult to ensure the accuracy of blade positioning, which can easily lead to stripping too deeply and damaging the internal conductor, or stripping too shallowly and leaving insulation residue, thus reducing the quality stability of wire stripping.

Detailed Implementation

[0015] 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.

[0016] Example: Please refer to Figures 1 to 7 According to an embodiment of the present invention, a technical solution is provided: an automatically adjustable core wire breaking device, comprising: a base box 1, a conveying component 2, a straightening component 3, and a breaking component 4; the conveying component 2, the straightening component 3, and the breaking component 4 are sequentially connected to the surface of the base box 1, and two sets of straightening components 3 are respectively located on the left and right sides of the conveying component 2; the breaking component 4 includes a second bracket 43 connected to the surface of the base box 1, and the upper and lower ends of the bracket are connected to a breaking blade 47 through a lifting component, and a limiting groove 44 is also connected to the bracket, and a guide wheel 46 is provided in the limiting groove 44, the breaking blade 47 passes through the limiting groove 44 and is located in the middle of the guide wheel 46, and the guide wheel 46 is driven by a second motor 41; a collection groove 5 is also provided on the surface of the base box 1, the collection groove 5 is located between the breaking component 4 and the conveying component 2, and a conveyor belt 51 is connected to the bottom end of the collection groove 5.

[0017] The conveying assembly 2, with the aforementioned structure, is connected to the surface of the base box 1 and serves as the "entry point" for the core wire to enter the equipment's processing flow. Its main function is to stably and uniformly convey the core wire to be processed to the subsequent straightening assembly 3 and shearing assembly 4. It can adjust the conveying speed according to the processing requirements of the core wire, ensuring a continuous and stable feed throughout the entire processing. The straightening assembly 3 consists of two sets, located on the left and right sides of the conveying assembly 2, respectively. Its core function is to correct the core wire delivered by the conveying assembly 2. Since the core wire may... Bending and deformation may occur. If the wire is directly subjected to the breaking process, it will lead to problems such as inaccurate breaking position and uneven breaking depth. The straightening component 3 uses a specific mechanical structure to squeeze and stretch the bent core wire, restoring it to a straight state and ensuring the accuracy of subsequent breaking processing. The breaking component 4 is the core part of the entire equipment to realize the core wire breaking function. It mainly consists of the second bracket 43, the lifting component, the breaking knife 47, the limiting groove 44, and the guide wheel 46. The lifting component is connected to the upper and lower ends of the second bracket 43 and is connected to the breaking knife 47. Its key... Its function is to achieve the up-and-down adjustment of the sheath-breaking blade 47. During the core wire conveying process, the sheath-breaking blade 47, under the action of the lifting component, contacts the outer sheath of the core wire at a suitable depth. As the core wire moves, it completes the sheath-breaking work. The limiting groove 44 can limit the core wire to prevent it from shifting during the sheath-breaking process. The guide wheel 46 rotates under the drive of the second motor 41. On the one hand, it can assist in the stable conveying of the core wire, reduce the friction between the core wire and the equipment, and protect the core wire from damage. On the other hand, it can also ensure that the sheath-breaking blade 47 always remains within the range of motion by cooperating with it. The core wire is broken at the correct position to further improve the breaking accuracy. After the breaking component 4 completes the core wire breaking operation, the generated outer sheath waste will fall off naturally. The collection tank 5 can collect this waste in a concentrated manner, preventing waste from being scattered on the equipment surface or in the working environment, and keeping the working environment clean. At the same time, the conveyor belt 51 connected to the bottom of the collection tank 5 can transport the waste in the collection tank 5 to the waste collection container outside the equipment in a timely manner, realizing the automated cleaning and transfer of waste. There is no need for frequent manual cleaning of the collection tank 5, which reduces the intensity of manual labor and improves the overall processing efficiency.

[0018] In this embodiment, the conveying assembly 2 includes a first support 22 connected to the base box 1. The lower end of the first support 22 is connected to a lower conveying wheel 26. The upper end of the second support 43 is connected to an upper conveying wheel 25 via a lifting plate 23. The top end of the first support 22 is connected to a first telescopic cylinder 21. The bottom end of the first telescopic cylinder 21 is connected to a connecting block 24. The bottom end of the connecting block 24 is connected to the lifting plate 23. The lifting plate 23 is slidably connected to the first support 22.

[0019] The upper conveyor wheel 25 is raised and lowered by the first telescopic cylinder 21, which can flexibly adjust the distance between the upper and lower conveyor wheels 26. For core wires with a thicker diameter, the cylinder extends to raise the upper conveyor wheel 25 and increase the distance; for core wires with a thinner diameter, the cylinder shortens to lower the upper conveyor wheel 25 and decrease the distance. This allows the conveying assembly 2 to adapt to core wires of different diameters and always maintain a suitable clamping force to avoid core wire slippage or damage, ensure stable conveying speed, and provide continuous and stable core wire feeding for subsequent straightening and exfoliation processes.

[0020] The straightening assembly 3 includes a base 31 connected to the base box 1. Side plates 32 are connected to both the front and rear sides of the base 31. Multiple straightening rollers 33 are connected to the opposite sides of the two side plates 32. A sliding groove is opened on the surface of the base 31. An extension block 34 is provided at the bottom end of the side plate 32 along the sliding groove. A first motor 36 is also connected to the bottom end of the base 31. The first motor 36 is connected to a double-headed lead screw 35. The double-headed lead screw 35 passes through the extension block 34 and is threadedly connected to the extension block 34.

[0021] The first motor 36 drives the double-headed lead screw 35 to rotate, thereby realizing the synchronous adjustment of the spacing between the straightening rollers 33 on both sides. For thick core wires, the spacing between the straightening rollers 33 can be increased to avoid excessive compression that could cause core wire deformation. For thin core wires, the spacing between the straightening rollers 33 can be decreased to ensure sufficient correction force and allow the bent core wire to return to straightness. This adjustable design breaks the limitation of the traditional fixed straightening rollers 33, which are "only suitable for a single specification of core wire", and greatly expands the straightening range of the equipment to meet the core wire processing needs in more scenarios.

[0022] The lifting assembly includes a column 45 connected to the surface of the base box 1. The top of the column 45 is connected to the top plate of the second bracket 43. The lifting assembly also includes a second telescopic cylinder 42 connected to the top of the second bracket 43. The bottom of the second telescopic cylinder 42 is connected to a lifting block 48. The bottom of the lifting block 48 is connected to a scalpel 47. The column 45 passes through the lifting block 48, and the lifting block 48 is slidably connected to the column 45.

[0023] The second telescopic cylinder 42 drives the lifting block 48 to raise and lower the sheathing knife 47. The telescopic range of the cylinder can be precisely controlled by air pressure or electronic control system (such as millimeter-level adjustment). The cutting depth of the sheathing knife 47 can be precisely adjusted according to the thickness of the outer sheath of the core wire, ensuring that the outer sheath is completely cut off, while avoiding excessive cutting and damage to the internal core wire (such as copper core or aluminum core). This solves the problem of "difficulty in controlling the depth" in traditional manual adjustment and greatly improves the sheathing quality.

[0024] Working principle: First, the parameters of each component are preset according to the core wire parameters (diameter, outer sheath thickness). The distance between the conveying wheels is adjusted by the first telescopic cylinder 21, the distance between the straightening rollers 33 is adjusted by the first motor 36 driving the double-headed lead screw 35, and the height of the sheath-breaking knife 47 is adjusted by the second telescopic cylinder 42. Then, the core wire is stably fed to the straightening component 3 by the conveying component 2. The two straightening components 3 straighten the core wire to a straight line for the second time by the staggered straightening rollers 33. Then, the straight core wire enters the sheath-breaking component 4, where the limiting groove 44 limits the movement and the guide wheel 46 assists in the conveying. The sheath-breaking knife 47 cuts the outer sheath to a preset depth. The waste generated by cutting falls into the collection trough 5 and is automatically transferred by the conveyor belt 51. Finally, the sheathed core wire is output. The equipment can continuously process in batches. When changing specifications, the parameters can be preset again. The whole process is automated and has high precision and high efficiency.
