Description

Technical Field

[0001] This invention relates to the field of heating wire manufacturing technology, and more specifically to an automatic cutting and peeling device for heating wire manufacturing. Background Technology

[0002] Existing heating wire structures typically consist of multiple independent metal heating cores arranged in parallel. Each core is first wrapped with a primary insulating layer (such as an inner silicone layer). Then, all the primary-coated cores are wrapped together as a whole within a metal braided shielding layer. Finally, an outermost layer of insulation (such as an outer silicone or PVC layer) is wrapped around the core. This structure provides excellent performance, but it also presents significant challenges for end-processing.

[0003] Current processing methods largely rely on manual or single-machine, step-by-step operations, including fixed-length cutting, manual stripping of the outer sheath at the ends, handling easily disintegrating braided layers, manually separating multiple inner core wires, and finally stripping the end insulation layer of each inner core wire individually. This process suffers from frequent interruptions, low automation, and significant bottlenecks in production efficiency. Furthermore, manual operation makes it difficult to precisely control the length and depth of stripping. When handling the braided layers, it easily leads to tangled wires and burrs; when stripping the inner core wires, it easily damages the conductors or results in incomplete stripping, leading to low product yield and risks of short circuits or overheating.

[0004] Existing general-purpose wire stripping machines are mainly designed for single- or double-layer ordinary cables and cannot effectively handle complex structures such as "outer insulation - braided layer - multiple independent inner insulation cores". They lack specialized braided layer processing mechanisms and multi-core synchronous separation and stripping mechanisms. Therefore, there is an urgent need in this field for an integrated device that can automate, precisely, and efficiently complete the entire process of cutting and stripping the inner cores of such complex heating wires. Summary of the Invention

[0010] As a preferred embodiment of an automatic cutting and peeling device for heating wire production, the second peeling mechanism includes a fifth driver and two opposing multi-core peeling blade groups, wherein the fifth driver is used to drive the two multi-core peeling blade groups to move relative to each other.

[0011] As a preferred embodiment of an automatic cutting and peeling device for heating wire production, the multi-core peeling knife assembly includes a second knife holder, a multi-core blade, and two rollers. The two rollers are telescopically mounted on the lower end of the second knife holder via spring rods, and the two rollers are respectively disposed on both sides of the multi-core blade.

[0012] As a preferred embodiment of an automatic cutting and peeling device for producing heating wires, the conveying module includes a pressure roller group and a support roller group arranged opposite to each other, forming a conveying channel through which the heating wire can pass. The pressure roller group includes a first drive shaft, a first conveyor belt, and at least two pressure shafts, with the first conveyor belt connecting the pressure shaft and the first drive shaft respectively. The support roller group includes a second conveyor shaft, a second conveyor belt, and at least two support shafts, with the second conveyor belt connecting the support shaft and the second drive shaft respectively.

[0013] As a preferred embodiment of an automatic cutting and peeling device for producing heating wires, the pressure roller assembly and / or the load-bearing roller assembly are elliptically mounted on one side of the conveyor channel via a sixth drive.

[0014] As a preferred embodiment of an automatic cutting and peeling device for producing heating wires, the outer surfaces of the first and second conveyor belts are respectively provided with elastic protrusion structures, and the extending direction of the elastic protrusion structures is perpendicular to the moving direction of the heating wires.

[0015] As a preferred embodiment of an automatic cutting and peeling device for producing heating wires, the elastic protrusion structure consists of a ring-shaped main body and several arc-shaped protrusions integrally formed on the ring-shaped main body, with an elastic cavity penetrating through the arc-shaped protrusions.

[0016] The automatic cutting and peeling equipment of this invention achieves full automation of the heating wire end processing by integrating four core modules: straightening, initial peeling, shielding layer treatment, and multi-core fine peeling.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0020] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0023] In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0024] In one embodiment of the present invention, such as Figure 1-11 As shown, an automatic cutting and peeling device for producing heating wires includes a straightening mechanism 1, a first peeling mechanism 2, a shielding layer cutting mechanism 3, and a second peeling mechanism 4 arranged in sequence, with a conveying module 5 corresponding to each adjacent mechanism.

[0025] Specifically, as an example, a braided multi-core heating wire is used as the workpiece in this embodiment and is processed at the end in this device. The braided multi-core heating wire consists of three independent metal heating cores, a braided shielding layer that wraps the three metal heating cores, and a secondary insulation layer that wraps the shielding layer, from the inside out. Each metal heating core is wrapped with a primary insulation layer.

[0026] The straightening mechanism 1, the first stripping mechanism 2, the shielding layer cutting mechanism 3, and the second stripping mechanism 4, arranged sequentially in this equipment, perform different end-processing steps. The straightening mechanism 1 straightens the metal heating core wire to ensure it remains straight during subsequent processing, preventing bending from affecting processing accuracy and product quality. The first stripping mechanism 2 removes the outermost primary insulation layer, preparing it for subsequent processes. The shielding layer cutting mechanism 3 combs and braids the shielding layer and cuts off excess material, exposing the internal metal heating core wire. The second stripping mechanism 4 further removes the secondary insulation layer, ultimately completing the end-processing of the braided multi-core heating wire. A transfer module 5, positioned between adjacent mechanisms, efficiently and stably transfers the workpiece from one mechanism to the next, achieving automation and continuity of the entire processing flow.

[0027] like Figure 2 As shown, the straightening mechanism 1 includes at least two mutually perpendicular straightening panels 11 and a plurality of straightening rollers 12 disposed opposite to each other on the straightening panels 11. A straightening channel is formed between the plurality of straightening rollers 12 through which the heating wire can pass. When the heating wire passes through the straightening channel, the straightening rollers 12 apply uniform and appropriate pressure. Utilizing the rotation and squeezing action of the rollers, the metal heating core wire, which may have been bent or twisted, is gradually straightened to a straight state, meeting the stringent requirements for wire straightness in subsequent processing. Simultaneously, the at least two mutually perpendicular straightening panels 11 straighten the heating wire from different directions, ensuring that the heating wire can be effectively straightened in both horizontal and vertical dimensions, further improving the straightening effect.

[0028] like Figure 3As shown, the first stripping mechanism 2 includes a first driver and two opposing combined blade groups. The first driver drives the two combined blade groups to move relative to each other. These combined blade groups not only strip the primary insulation layer but also cut the heating wire to a fixed length. In the stripping process, the conveying module 5 feeds a certain length of heating wire between the two combined blade groups. The first driver then drives the combined blade groups to move relative to each other, causing them to cut the outermost primary insulation layer through the V-shaped cutting edge of the blade groups. The conveying module 5 then retracts the heating wire, thus stripping off the primary insulation layer. In the cutting process, the cutting depth of the combined blade groups is greater than that in the stripping process, thereby completely cutting the heating wire.

[0029] The first peeling mechanism 2 also includes a second driver, which drives the combined blade assembly to move along a first direction. The combined blade assembly includes a first blade holder 21 and cutting blades 22 and single-core blades 23 arranged side-by-side along the first direction. Since the cutting volume and wear rate of the peeling and cutting processes are different, the cutting blades 22 and single-core blades 23 perform the two processes separately. In actual use, when the second driver drives the movement along the first direction, the cutting blades 22 and single-core blades 23 will function sequentially. When the heating wire needs to be cut to a fixed length, the cutting blade 22 accurately cuts the heating wire according to a preset length position, ensuring that the length of each section of heating wire meets production requirements. The single-core blade 23, when peeling the primary insulation layer, precisely cuts into the position between the primary insulation layer and the metal heating core wire, separating the primary insulation layer from the metal heating core wire without damaging it, ensuring the quality and efficiency of the peeling process. Through the coordinated operation of the first and second drivers, and the reasonable arrangement of the cutting blade 22 and the single-core blade 23, the first peeling mechanism 2 can efficiently and accurately complete the peeling and fixed-length cutting of the heating wire.

[0030] like Figure 4-9 As shown, the shielding layer cutting mechanism 3 includes a tubular blade holder 31, an annular cutter 32, a third driver, and two opposing rotating roller brushes 33. The annular cutter 32 is movably mounted on one end of the tubular blade holder 31 via a fourth driver. A combing cavity is provided between the tubular blade holder 31 and the annular cutter 32. The two rotating roller brushes 33 are respectively positioned opposite each other on both sides of the combing cavity. The third driver is used to drive the two rotating roller brushes 33 to move relative to each other. A transmission channel is provided through the tubular blade holder 31 and the annular cutter 32.

[0031] Once the heating wire enters the shielding layer cutting mechanism 3, the third driver is activated, causing two rotating brushes 33 to move relative to each other. The bristles of the rotating brushes 33 initially comb the braided metal shielding layer, making it more regular. During this process, the heating wire moves away from its end, combing the braided shielding layer at the end of the heating wire into relatively vertical metal wires. Next, the rotating brushes 33 rotate in the opposite direction, and the heating wire also moves in the same direction, thus combing the metal wires in the opposite direction onto the tubular cutter holder 31, exposing the metal wires. Then, the fourth driver is activated, driving the annular cutter 32 to move towards the tubular cutter holder 31, thereby precisely cutting off the exposed excess braided shielding layer, neatly removing the excess portion, and fully exposing the internal metal heating core wire, preparing it for subsequent processing steps. The transmission channel plays a guiding and stabilizing role in the entire process, ensuring that the heating wire can smoothly complete the corresponding processing steps within the shielding layer cutting mechanism 3, ensuring the efficiency and accuracy of the entire shielding layer removal process.

[0032] The above-described operating sequence is used to remove the shielding layer from the head of the heating wire. Removing the shielding layer from the tail of the heating wire is done in the reverse order. Specifically, when processing the tail of the heating wire, the entire heating wire first enters the annular cutter 32. At this time, the third driver is activated, driving two rotating brushes 33 to move relative to each other. The bristles of the rotating brushes 33 initially comb the braided metal shielding layer, combing the braided shielding layer at the tail of the heating wire into relatively vertical metal wires. During this process, the heating wire moves towards the tail. Then, the rotating brushes 33 rotate in the opposite direction, and the heating wire also moves in the opposite direction, combing the metal wires onto the annular cutter 32 to expose them. Finally, the fourth driver is activated, and the annular cutter 32 moves the heating wire towards the tubular cutter holder 31, precisely cutting off the exposed excess braided shielding layer to fully expose the internal metal heating core wire, completing the shielding layer removal process at the tail of the heating wire. By flexibly adjusting the operation sequence, the shielding layer cutting mechanism 3 can meet the different shielding layer removal requirements at the head and tail of the heating wire, improving the applicability of the equipment and the comprehensiveness of the processing.

[0033] like Figure 10 As shown, the second peeling mechanism 4 includes a fifth driver and two opposing multi-core peeling blade assemblies. The fifth driver drives the two multi-core peeling blade assemblies to move relative to each other. Each multi-core peeling blade assembly includes a second blade holder 41, multi-core blades 42, and two rollers 43. The two rollers 43 are telescopically mounted on the lower end of the second blade holder 41 via spring rods 44, and are respectively disposed on both sides of the multi-core blades 42. The multi-core blades 42 have multiple V-grooves of corresponding number and depth corresponding to the number and diameter of the core wires.

[0034] The second stripping mechanism 4 is used to remove the primary insulation layer of multiple metal heating core wires in one operation. In practical applications, the conveying module 5 transports the heating wires processed in the previous steps to the second stripping mechanism 4. The fifth driver is activated, driving the two multi-core stripping blade groups to move relative to each other. When the heating wire enters between the two multi-core stripping blade groups, the two rollers 43 first contact the heating wire. Due to the extensibility of the spring rod 44, the rollers 43 will make a certain degree of adaptive adjustment according to the thickness of the heating wire, stably clamping the heating wire to ensure that the heating wire will not shift during the subsequent stripping process. The clamping pressure is used to press the multiple core wires into a side-by-side arrangement. Next, the multi-core blade 42 begins to function, precisely cutting between the secondary insulation layer and the metal heating core wire. With the continuous relative movement of the two multi-core stripping blade groups, the multi-core blade 42 peels the secondary insulation layer from the multiple metal heating core wires simultaneously. In this process, the roller 43 not only plays a role in clamping and stabilizing, but also assists the multi-core blade 42 to a certain extent, making the stripping process smoother and ensuring the quality and efficiency of stripping. Through this design of the second stripping mechanism 4, the stripping of the secondary insulation layer of multiple metal heating core wires can be completed efficiently and accurately, ultimately completing the entire end processing process of the braided multi-core heating wire.

[0035] like Figure 11 As shown, the conveying module 5 includes a pressure roller group 51 and a support roller group 52 arranged opposite to each other. A conveying channel through which the heating wire can pass is formed between the pressure roller group 51 and the support roller group 52. The pressure roller group 51 includes a first drive shaft 511, a first conveyor belt 512, and at least two pressure shafts 513. The first conveyor belt 512 is connected to the pressure shaft 513 and the first drive shaft 511 respectively. The support roller group 52 includes a second conveyor shaft 521, a second conveyor belt 522, and at least two support shafts 523. The second conveyor belt 522 is connected to the support shaft 523 and the second drive shaft respectively. The first drive shaft 511 and the second drive shaft are each connected to a drive motor.

[0036] When the conveying module 5 is operating, the drive motor starts, causing the first drive shaft 511 and the second drive shaft to rotate. The first drive shaft 511 drives at least two pressure shafts 513 to rotate via the first conveyor belt 512, and the second drive shaft drives at least two support shafts 523 to rotate via the second conveyor belt 522. After the heating wire enters the conveying channel formed between the pressure wheel group 51 and the support wheel group 52, the pressure shafts 513 and the support shafts 523 apply pressure to the heating wire from the top and bottom sides respectively, stably clamping it within the conveying channel. As the pressure shafts 513 and the support shafts 523 rotate, the heating wire moves forward within the conveying channel, being conveyed from one mechanism to the next.

[0037] In this embodiment, the pressure roller assembly 51 is flexibly mounted on the opposite side of the bearing roller assembly 52 via a sixth driver. The sixth driver can flexibly adjust the height of the pressure roller assembly 51 according to the diameter of the heating wire. When the heating wire is thicker, the sixth driver drives the pressure roller assembly 51 to rise a certain distance, increasing the distance between the pressure roller assembly 51 and the bearing shaft 523, ensuring that the heating wire can smoothly enter the conveying channel and be stably clamped. When the heating wire is thinner, the sixth driver drives the pressure roller assembly 51 to descend, reducing the distance between the pressure roller assembly 51 and the bearing shaft 523, allowing the heating wire to be clamped more tightly, preventing slippage or deviation during conveying. Through this height-adjustable design, the pressure roller assembly 51 can adapt to the conveying requirements of heating wires of different specifications, further improving the versatility and stability of the conveying module 5, and ensuring the smooth operation of the entire automatic cutting and peeling equipment process. Furthermore, the bearing roller assembly 52 can also be equipped with corresponding lifting components to achieve the same technical effect.

[0038] Both the first conveyor belt 512 and the second conveyor belt 522 have corresponding elastic protrusion structures 53 on their outer surfaces. The extension direction of the elastic protrusion structures 53 is perpendicular to the movement direction of the heating wire. These elastic protrusion structures 53 can increase the contact area with the surface of the heating wire during the conveying process, forming an interlocking effect. When the heating wire moves in the conveying channel, the elastic protrusion structures 53 will make close contact with the surface of the heating wire, generating a certain frictional resistance, thereby better preventing the heating wire from slipping during the conveying process. Moreover, since the elastic protrusion structures 53 have a certain degree of elasticity, they will not damage the surface of the heating wire when pressure is applied to clamp the heating wire, ensuring both the stability of the conveying and the quality of the heating wire. At the same time, this design of the elastic protrusion structure 53 can also adapt to heating wires of different thicknesses and materials, further improving the applicability and reliability of the conveying module 5, ensuring that the heating wire can be accurately and stably conveyed from one mechanism to the next, and guaranteeing the efficient operation of the entire automatic cutting and peeling equipment.

[0039] Specifically, especially when processing short heating wires, after the multi-core stripping process of the second stripping mechanism 4, the end of the heating wire is pressed by the roller 43, resulting in a reduction in its vertical diameter. During process handover, the end of the heating wire may not be stably held and conveyed by the subsequent conveying module 5. To address this issue, this equipment incorporates elastic protrusions 53 on the conveyor belt. When conveying short heating wires, even after the vertical diameter of the heating wire end is reduced due to the pressing of the roller 43, the elastic protrusions 53 can still maintain a close fit with the surface of the heating wire due to their unique shape and elasticity. These elastic protrusions 53 embed into the subtle undulations on the surface of the heating wire caused by the diameter change, creating a "gripping" effect that greatly increases friction. Even with a smaller diameter end, the heating wire can be stably held within the conveying channel without slippage or failure to be conveyed. Moreover, due to the elasticity of the elastic protrusion structure 53, excessive pressure will not be applied to the already reduced portion of the heating wire end during the clamping process, thus avoiding damage or deformation of the heating wire end due to excessive pressure. This ensures that the heating wire can still be smoothly and stably conveyed to the subsequent processing mechanism after the multi-core stripping process, ensuring the smoothness and accuracy of the entire automatic cutting and stripping equipment in processing short-sized heating wires.

[0040] The elastic protrusion structure 53 consists of an annular body 531 and several arc-shaped protrusions 532 integrally formed on the annular body 531. Each arc-shaped protrusion 532 has a through-hole elastic cavity. This design allows the arc-shaped protrusion 532 to deform under pressure, better adapting to changes in the shape of the heating wire surface. This deformation capability not only enhances the interlocking effect between the elastic protrusion structure 53 and the heating wire but also further increases frictional resistance, ensuring the heating wire remains stable during transmission. Simultaneously, the presence of the elastic cavity allows the arc-shaped protrusions 532 to quickly release stored elastic potential energy upon returning to their original shape, preparing for the next clamping and transmission. Furthermore, this design extends the service life of the elastic protrusion structure 53 and reduces equipment maintenance costs.

[0041] In this embodiment, the first driver, second driver, third driver, fourth driver, fifth driver and sixth driver adopt a linear drive cylinder structure, which can also be replaced by linear drive mechanisms such as linear motors.

[0042] This invention's automatic cutting and stripping equipment integrates four core modules: straightening, initial stripping, shielding layer treatment, and multi-core fine stripping, achieving full automation of the heating wire end processing. The straightening mechanism 1 employs a bidirectional roller assembly design, effectively eliminating wire bending stress and ensuring subsequent processing accuracy. The first stripping mechanism 2, through the synchronous movement of combined blades, precisely controls the stripping length of the outer insulation layer, avoiding damage to the internal structure. The shielding layer cutting mechanism 3 innovatively introduces a rotating roller brush 33 combing technology, simultaneously cutting the braided layer and neatly bundling the metal wires, completely solving the problem of burrs easily generated in traditional processes. The second stripping mechanism 4's multi-core synchronous separation system, through the coordinated operation of the retractable roller 43 and the multi-core blade 42, achieves independent stripping of multiple inner core wires, with the stripping depth error controlled within ±0.05mm. This equipment integrates traditional step-by-step processes into a continuous production line, increasing processing efficiency by more than 8 times compared to manual operation, and raising the product qualification rate from 65% to 99.2%. It is particularly suitable for fields with extremely high cable reliability requirements, such as aerospace and new energy vehicles.
