Wire insulation gate cutting device

Abstract

This invention discloses a metal wire insulation grid cutting device, belonging to the technical field of metal wire insulation grid cutting. The device features a pair of cutting wheels arranged opposite each other within its frame. These two wheels work together precisely to cut uniform slits in the pipeline. The cutting blade has an adjustable diameter, ensuring that the operator can adjust the cutting depth according to actual needs, effectively avoiding problems of excessive or insufficient cutting. Furthermore, the first clamping wheel in the device is equipped with a ventilation system. This system achieves dual management of the stripped metal wire surface insulation layer through the suction and blowing functions of the ventilation holes: in suction mode, the metal wire surface insulation layer is firmly adsorbed within the annular groove, guiding its orderly movement; while in blowing mode, the metal wire surface insulation layer is smoothly pushed out of the annular groove and orderly discharged through the waste outlet.

Description

Technical Field

[0001] This invention relates to the field of insulating grid cutting technology, and more specifically to a metal wire insulating grid cutting device. Background Technology

[0002] With the rapid development of the electronics industry, metal wires, as an important medium for connecting electronic components, directly affect the performance and manufacturing cost of the entire product due to their processing quality and efficiency. Traditional metal wire insulation barrier cutting methods mostly rely on manual operation or simple mechanical equipment, which suffers from problems such as uneven insulation barrier cutting, low efficiency, and easy damage to the metal core wire, making it difficult to meet the needs of automated production.

[0003] Especially in the manufacturing process of precision electronic products, the insulation layer on the surface of metal wires needs to be precisely and efficiently stripped while ensuring the integrity of the metal core wire. This requires insulation barrier cutting equipment to have a high level of automation, precise cutting capabilities, and good waste handling capabilities. However, existing metal wire insulation barrier cutting devices often struggle to meet these requirements simultaneously, resulting in low production efficiency and inconsistent product quality.

[0004] Therefore, developing a metal wire insulation grid cutting device that can automatically, accurately, and efficiently strip the surface insulation layer of metal wires while achieving orderly waste discharge has become a technical problem that the electronics industry urgently needs to solve. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the present invention aims to provide a metal wire insulation grid cutting device capable of separating the surface insulation layer of a metal wire from the metal core wire.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a metal wire insulation grid cutting device, including a box body, the inside of the box body is provided with a channel for the metal wire to move, the two ends of the box body are respectively provided with a feed hole and a discharge hole, and both sides of the box body are provided with a waste outlet.

[0007] The interior of the box is provided with a pushing component, a cutting component and a separating component in sequence along the conveying direction of the channel;

[0008] The pushing component includes multiple pushing groups, each pushing group including two pushing rollers, which are respectively arranged on the upper and lower sides of the channel;

[0009] The cutting assembly includes two cutting wheels symmetrically arranged along the center of the channel. When the metal wire passes through the channel, the two cutting wheels can form a cutting slit on the surface of the metal wire.

[0010] The number of separation components is two sets, and the two sets of separation components are respectively arranged on both sides of this plane. Each set of separation components includes a first clamping wheel and a second clamping wheel that can rotate synchronously and in opposite directions. During the rotation, the first clamping wheel and the second clamping wheel can push the insulation layer on the surface of the metal wire to move.

[0011] Preferably, the outer ring surface of the first clamping wheel is provided with an annular groove, and the outer ring surface of the second clamping wheel is provided with an annular protrusion, and the gap between the annular groove and the annular protrusion is adapted to the insulating layer on the surface of the metal wire.

[0012] Preferably, the first clamping wheel is an annular body, and the interior of the annular groove is provided with multiple ventilation holes. The first clamping wheel is rotatably sleeved on the inner column, which is fixed to the frame. The inner column is provided with an air inlet groove and an air outlet groove. The air inlet groove faces the channel for the metal wire to move, and the air outlet groove is away from the channel for the metal wire to move. When the first clamping wheel rotates, the ventilation holes are connected to the air inlet groove, and the gas enters the interior of the air inlet groove from the outside through the ventilation holes, generating suction on the insulation layer of the metal wire surface outside the ventilation holes. When the ventilation holes are connected to the air outlet groove, the gas flows outward from the air outlet groove through the ventilation holes and generates thrust on the insulation layer of the metal wire surface.

[0013] Preferably, the air inlet slots on both sides are connected to a duct of the blower through a first connecting pipe, and the two air outlet slots are connected to another duct of the blower through a second connecting pipe.

[0014] Preferably, a toothed sleeve is fixed to the bottom of the first clamping wheel, the toothed sleeve extends into the interior of the frame, and a motor for driving the toothed sleeve to rotate is installed inside the frame.

[0015] Preferably, the cutting wheel has a cutting edge on its periphery, and the cutting edge is a convex circle with a variable diameter.

[0016] Preferably, the two cutting wheels are rotatably mounted on the frame via connecting shafts, and each connecting shaft is fixed with a linkage gear that meshes with each other. A motor for driving either connecting shaft to rotate is fixed inside the frame.

[0017] Preferably, a guide wheel is rotatably mounted between the cutting wheel and the inner column, and there are two guide wheels, which are respectively arranged on both sides of the cutting wheel.

[0018] Preferably, the outer ring surfaces of the push roller and the guide wheel are both arc surfaces adapted to the metal wire.

[0019] Preferably, a guide cylinder is provided between the pusher group and the cutting wheel along the conveying direction of the channel. The guide cylinder is fixed inside the frame and sleeved outside the channel. The internal through hole of the guide cylinder is adapted to the metal wire.

[0020] The beneficial effects of this invention are as follows:

[0021] This metal wire insulation grid cutting device features a pair of rotatable cutting wheels. These wheels are positioned on the upper and lower sides of the pipeline to be processed, creating a uniform slit along the line. The cutting blades on the wheels have an adjustable diameter, allowing operators to flexibly adjust the distance between the blades and the pipeline according to specific needs. This effectively avoids cutting too deeply into the metal core or undercutting, ensuring the precision of the insulation grid cutting.

[0022] Furthermore, the device incorporates a ventilation system within the first clamping wheel, which includes ventilation holes. These holes not only generate suction to hold the stripped insulation layer from the metal wire surface within specially designed annular grooves, ensuring smooth movement of the insulation layer during subsequent processing, but also, when needed, can switch to a blowing mode to gently push the stripped insulation layer out of the annular grooves and guide it out through the waste outlet in an orderly manner, simplifying the cleaning work after cutting the insulation grid.

[0030] The present invention is illustrated below with specific embodiments, but these are not intended to limit the invention.

[0031] Example 1

[0032] like Figures 1-2 As shown in this embodiment, a metal wire insulation grid cutting device includes a housing. The housing has an internal channel for the movement of the metal wire. The cross-section of this channel is designed to be circular, with dimensions precisely matching the outer diameter of the metal wire, ensuring smooth and unobstructed passage. The housing has an inlet and an outlet at each end. The metal wire first enters the channel through the inlet. Once the wire passes through the channel, it is automatically insulated by the insulation grid cutting device inside the housing. After the insulation grid cutting process is completed, the processed metal wire is smoothly discharged from the outlet. Waste outlets are located on both sides of the housing. After the metal wire undergoes insulation grid cutting, the outer insulation layer is effectively peeled off, exposing the inner metal core. The peeled-off insulation waste is then smoothly discharged through the waste outlets.

[0033] Inside the housing, along the conveying direction of the channel, are sequentially arranged a pushing component, a cutting component, and a separating component. The pushing component, located near the inlet of the channel, not only propels the metal wire smoothly within the channel as it enters but also organizes the wire, ensuring it remains straight before entering subsequent processes. Next, the metal wire encounters the cutting device, which precisely cuts slits in the insulation layer of the metal wire's outer surface, laying the foundation for the subsequent separation of the insulation layer from the metal layer. Then, the separating component takes over, effectively separating the insulation layer from the internal metal layer, and discharging the wires through different outlets, achieving an orderly processing flow.

[0034] The pushing assembly includes multiple pushing groups, each of which includes two pushing rollers 2. The two pushing rollers 2 are respectively arranged on the upper and lower sides of the channel. The symmetrical distribution of the pushing rollers 2 significantly reduces the risk of compression of the metal wire caused by the gap between the two pushing rollers 2. At the same time, by configuring multiple pushing rollers 2, the metal wire can be straightened more effectively, ensuring that the metal wire maintains an ideal straight state before entering the subsequent processing stage.

[0035] The cutting assembly includes two cutting wheels 4 symmetrically arranged along the center of the channel. When the metal wire passes through the channel, the two cutting wheels 4 can form a cutting slit on the surface of the metal wire. In this embodiment, the cutting wheels 4 are distributed vertically, so that the cutting slit is set on the upper and lower sides of the metal wire. This layout allows the insulation layer on the surface of the subsequently cut metal wire to be discharged from the waste outlets on both sides of the frame 1.

[0036] There are two sets of separation components, positioned on opposite sides of the plane. Each set includes a first clamping wheel 5 and a second clamping wheel 6 that rotate synchronously and in opposite directions. Both clamping wheels 5 and 6 are horizontally arranged, facilitating the discharge of the stripped metal wire from the waste outlet. During rotation, the clamping wheels 5 and 6 push the insulation layer on the surface of the metal wire. As the insulation layer is pushed, the clamping wheels 5 and 6 not only provide a forward thrust but also apply a clamping force simultaneously. This combined clamping and thrust forces cause the insulation layer on both sides of the metal wire to be pulled outwards, effectively promoting the separation process between the insulation layer and the core metal wire, making the separation operation smoother.

[0037] Example 2

[0038] like Figures 1-4 As shown, based on Embodiment 1, this embodiment provides a device for guiding the surface insulation layer of the cut metal wire to be discharged from the waste outlet, as detailed below:

[0039] The outer ring surface of the first clamping wheel 5 is provided with an annular groove, and the outer ring surface of the second clamping wheel 6 is provided with an annular protrusion. The gap between the annular groove and the annular protrusion is adapted to the surface insulation layer of the metal wire. The annular groove and the annular protrusion on the surface insulation layer of the metal wire match each other. This shape adaptation ensures that the arc surface above the metal wire can fit more tightly and firmly inside the annular groove, effectively preventing the surface insulation layer of the metal wire from accidentally falling off from the annular groove.

[0040] The first clamping wheel 5 is an annular body with multiple ventilation holes inside the annular groove. The first clamping wheel 5 is rotatably sleeved on the inner column 7, which is fixed to the frame 1. The inner column 7 has an air inlet groove 8 and an air outlet groove 9 inside. During the rotation of the annular body, it periodically communicates with the air inlet groove 8 and the air outlet groove 9. At the same time, at different stages of rotation, it also comes into contact with other areas on the inner column 7. The air inlet groove 8 faces the channel for the metal wire to move, and the air outlet groove 9 is away from the channel for the metal wire to move. When the first clamping wheel 5 rotates... When the ventilation hole is connected to the air inlet slot 8, gas enters the interior of the air inlet slot 8 from the outside through the ventilation hole, generating a suction force on the insulation layer of the metal wire surface outside the ventilation hole. When the ventilation hole is connected to the air outlet slot 9, gas flows outward from the air outlet slot 9 through the ventilation hole, generating a thrust force on the insulation layer of the metal wire surface. When the ventilation hole is connected to the air inlet slot 8, the resulting suction effect tightly adsorbs the insulation layer of the cut metal wire surface onto the annular groove. This suction force causes the insulation layer of the metal wire surface to adhere tightly to the annular groove and move together with the corresponding first clamping wheel 5. When the ventilation hole is connected to the air outlet slot 9, the resulting thrust acts on the insulation layer of the metal wire surface, causing it to detach from the adsorption of the annular groove, approach the second clamping wheel 6, and finally be able to smoothly exit through the waste port.

[0041] The air inlet slots 8 on both sides are connected to one duct of the blower 13 via the first connecting pipe 11, and the two air outlet slots 9 are connected to the other duct of the blower 13 via the second connecting pipe 12. Under the action of the blower 13, the gas can flow smoothly in a preset path. This process begins in the air inlet slots 8, is guided by the air inlet pipe, then passed through the air outlet pipe, and finally discharged from the air outlet slots 9. This flow mechanism effectively achieves the expected effect of gas adsorption and directional displacement.

[0042] Example 3

[0043] like Figures 1-6 As shown, based on Embodiment 1 and Embodiment 2, this embodiment provides a metal wire stabilization device, as detailed below:

[0044] A toothed sleeve 10 is fixed to the bottom of the first clamping wheel 5. The toothed sleeve 10 extends into the interior of the frame 1. A motor for driving the toothed sleeve 10 to rotate is installed inside the frame 1. A gear is fixed on the output shaft of the motor. The gear meshes with the toothed sleeve 10, thereby driving the toothed sleeve 10 to rotate. The toothed sleeve 10 drives the first clamping wheel 5 to rotate.

[0045] The cutting wheel 4 is equipped with a cutting blade on its periphery. The cutting blade is a convex circle with a variable diameter, which has the ability to precisely cut the insulation layer on the surface of the metal wire. Its unique variable diameter design allows users to flexibly adjust the distance between the cutting blade and the metal core wire according to actual needs. This feature is particularly important when dealing with overcutting or incomplete cutting that may occur during the cutting process, because it allows the operator to make fine adjustments to the cutting blade in real time to ensure the accuracy and efficiency of the cutting operation.

[0046] Two cutting wheels 4 are mounted on the frame 1 via a shaft. Each shaft is fixed with a linkage gear 15, which meshes with each other. A motor for driving either shaft is fixed inside the frame 1. When the two meshing linkage gears 15 are engaged, if one of the gears is driven to rotate by the motor, the two gears will work together, each driving their respective connected shafts to rotate at the same speed but in opposite directions.

[0047] Two guide wheels 14 are rotatably mounted between the cutting wheel 4 and the inner column 7, respectively located on both sides of the cutting wheel 4. A motor for driving the guide wheels 14 to rotate is installed inside the frame 1. The two guide wheels 14 can apply axial tension to the surface insulation layer of the cut metal wire, making the cutting easier.

[0048] The outer ring surfaces of the push roller 2 and the guide wheel 14 are both arc surfaces adapted to the metal wire, and the arc surfaces are more likely to contact the metal wire and generate a clamping force.

[0049] A guide cylinder 3 is provided between the pusher group and the cutting wheel 4 along the conveying direction of the channel. The guide cylinder 3 is fixed inside the frame 1 and sleeved outside the channel. The internal through hole of the guide cylinder 3 is adapted to the metal wire. The guide cylinder 3 guides the metal wire and prevents the path of the wire from deviating.

[0050] Working principle:

[0051] During the process of introducing the metal wire into the frame 1, the metal wire is first fed in through the inlet, and then the metal wire encounters a series of carefully designed push rollers 2. These push rollers 2 not only tightly press the metal wire, but also work together to push it forward, ensuring that the metal wire is organized into a relatively straight path during its journey.

[0052] After initial shaping by the push roller 2, the metal wire continues to move forward to the guide cylinder 3 area. Then, two cutting wheels 4, positioned one above the other, precisely cut the surface of the metal wire's insulation layer. This step leaves two corresponding slits on the insulation layer, marking the completion of the cutting process.

[0053] The cut metal wire is then guided by guide wheel 14 to the position of the first clamping wheel 5. The first clamping wheel 5 has ventilation holes, which play a crucial role at this stage. These holes apply a suction force to the insulation layer on the surface of the freshly cut metal wire, causing the insulation layer to move tightly against the surface of the first clamping wheel 5. When the insulation layer is pulled into the narrow gap between the first clamping wheel 5 and the second clamping wheel 6, these two sets of clamping wheels not only apply clamping force and pressure to the insulation layer but also achieve further processing through their special design.

[0054] During the passage of the metal wire surface insulation layer between the first clamping wheel 5 and the second clamping wheel 6, the ventilation holes on the first clamping wheel 5 change their function from suction to blowing. This airflow effectively blows away the metal wire surface insulation layer that is in close contact with the outer ring surface of the first clamping wheel 5 and guides it to move towards the waste outlet, thus achieving effective separation of the metal wire surface insulation layer from the metal core wire.

[0055] Meanwhile, the two second clamping wheels 6 located at the rear of the system are responsible for pushing the metal core wire left after cutting to continue moving forward, and finally being discharged smoothly through the outlet of the channel, completing the entire processing process.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the present invention without departing from the spirit and scope of the present invention. Any modifications or partial substitutions should be covered within the scope of the claims of the present invention.
