Description

Technical Field

[0001] This utility model belongs to the field of metal wire paint stripping technology, and in particular relates to an automatic following paint stripping knife. Background Technology

[0002] Enamelled wire refers to a metallic conductor with an insulating varnish coating used for winding electromagnetic coils; it is also called electromagnetic wire. It is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then undergoes multiple coatings and baking processes. However, producing products that meet both standard requirements and customer demands is not easy. It is affected by factors such as raw material quality, process parameters, production equipment, and the environment. Therefore, the quality characteristics of various enamelled wires differ, but they all possess four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

[0003] For example, Chinese utility model patent application number CN201720669785.0 discloses a wire stripping machine, the structure of which includes a motor housing, a transparent cover, and a stripping drill bit. The stripping drill bit passes through the transparent cover and is connected to the front of the motor housing. The transparent cover is movably connected to the front of the motor housing. The motor housing has a body, a knob, a push-button switch, and a heat sink. The knob and push-button switch are respectively located on the right side of the front of the body, and the heat sink is located on the right side of the body. The stripping drill bit has a stripping guide and a connecting rod. The stripping guide is connected to the connecting rod. The stripping guide has a three-position stripping rod, a wire opening, a surrounding opening, and a transparent guide mask. The three-position stripping rod passes through the wire opening, and the wire opening is connected to the surrounding opening. The three-position stripping rod, the wire opening, and the surrounding opening are located inside the transparent guide mask. The beneficial effects of this utility model are that the stripping drill bit opening passes through the transparent cover and is connected to the front of the motor housing, and a three-position stripping rod is used for stripping, ensuring a clean and neat stripped surface, reducing damage caused by stripping, and improving quality.

[0004] The aforementioned enameled wire stripping machine has the following technical defects: Since the three-position stripping lever cannot automatically adjust its position, when stripping the enameled wire terminals, it is necessary to first straighten the wire terminals and then insert the straightened terminals between the three-position stripping levers. The wire terminals are then stripped by rotating the three-position stripping levers. However, straightening the wire terminals before stripping adds a step to the process, which not only increases labor costs but also reduces processing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an automatic following paint stripper, which aims to solve one of the technical problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides an automatic following paint stripper, comprising:

[0007] An output shaft, one end of which is fixedly connected to the shaft of a drive gear; a rotating head is also rotatably mounted outside the output shaft; and

[0008] Multiple paint stripping blades are mounted on the rotating head and rotate around the output shaft via a connecting shaft. Each of the multiple paint stripping blades has a cutting edge on one side that is close to each other, and a paint stripping position is formed between the multiple cutting edges. Each connecting shaft is fixedly connected to the shaft of a driven gear, and each driven gear is meshed with the driving gear.

[0009] The driving gear is used to drive the driven gear to rotate and revolve, so that the blade of at least one of the paint stripping tools is in close contact with the outer wall of the wire to be stripped for paint stripping, and the blade of at least one of the paint stripping tools can automatically follow the bending of the wire to be stripped and adaptively adjust its position by rotating.

[0010] Optionally, it also includes a plurality of elastic reset members; each of the elastic reset members is connected at both ends to a connecting shaft and the rotating head respectively, and the elastic reset member has a reset elastic force that drives the blade of the paint stripper to rotate outward.

[0011] Optionally, each of the connecting shafts is provided with a connecting block, and both ends of each of the elastic reset members are respectively connected to a connecting block and the rotating head.

[0012] Optionally, each of the connecting blocks is provided with a first connecting member, the rotating head is provided with a plurality of second connecting members, the elastic reset member is a tension spring, and the two ends of each tension spring are respectively sleeved on a first connecting member and a second connecting member.

[0013] Optionally, the outer wall of the rotating head is evenly distributed with a plurality of receiving grooves, and the plurality of connecting blocks are respectively housed in the plurality of receiving grooves; the receiving groove is provided with a first limiting platform, which is used to limit the maximum angle of outward rotation of the blade of the paint stripping tool when the first limiting platform abuts against the connecting block.

[0014] Optionally, the outer wall of the rotating head is evenly distributed with multiple receiving grooves, and the multiple connecting blocks are respectively housed in the multiple receiving grooves; the rotating head is provided with a second limiting platform on one side of the receiving groove, and the second limiting platform is used to limit the maximum angle of inward rotation of the blade of the paint stripping tool when it abuts against the connecting block.

[0015] Optionally, the rotating head is rotatably fitted with a limiting ring, the limiting ring having multiple limiting grooves, one end of each of the multiple connecting blocks extending into the multiple limiting grooves, and one wall of each limiting groove serving as the second limiting platform; the limiting ring is provided with at least one fastener, the fastener being used to lock or release the limiting ring.

[0016] Optionally, the front end of the rotating head is provided with a protective cover, which covers a plurality of the paint stripping blades; the front end of the protective cover is provided with a wire insertion hole facing the paint stripping position.

[0017] Optionally, each of the paint stripping knives is mounted on a knife holder, and multiple knife holders are respectively mounted on one end of multiple connecting shafts.

[0018] Optionally, the rotating head is provided with a receiving cavity, in which the driving gear and the plurality of driven gears are all received.

[0019] Compared with the prior art, the above-mentioned technical solutions of the automatic following paint stripper provided in this utility model embodiment have at least one of the following technical effects:

[0020] During operation, the wire to be stripped of its coating, which is wound with an electromagnetic coil, is first inserted into the stripping position. Then, the output shaft drives the drive gear to rotate, which in turn drives the driven gear to rotate on its own axis. The driven gear, through the connecting shaft, drives the blade of the stripping tool to rotate inward, so that the blade of at least one stripping tool is pressed against the outer wall of the wire to be stripped. At this time, the resistance of the wire to be stripped to the blade causes the driven gear to stop driving the blade to rotate inward. The driven gear then revolves around the drive gear under the drive of the drive gear, so that the blade of the stripping tool strips the coating from the outer wall of the wire to be stripped. When stripping the coating from a bent section of a wire, at least one stripping tool can rotate outward around the connecting axis under the push of the bent section of the wire, automatically adjusting its position to follow the bent section of the wire to be stripped. Alternatively, at least one stripping tool can rotate inward around the connecting axis under the drive of a driving gear and a driven gear, automatically adjusting its position to follow the bent section of the wire to be stripped. This allows the blade of at least one stripping tool to rotate outward or inward with the bent section of the wire to be stripped, ensuring that the blade remains in close contact with the outer wall of the wire for effective coating removal. Therefore, the automatic following stripping tool of this invention can strip the coating from bent wires without the need to straighten the wire before stripping, reducing the need for straightening the wire, lowering labor costs, and improving processing efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not 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 this utility model.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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 embodiment of the invention according to the specific circumstances.

[0037] In one embodiment of this utility model, reference is made to Figures 1-3 An automatic paint stripper is provided, comprising an output shaft 410 and a plurality of paint stripper blades 430.

[0038] Among them, reference Figures 1-3 One end of the output shaft 410 is fixedly connected to the shaft of a drive gear 411. A rotating head 420 is also rotatably mounted outside the output shaft 410.

[0039] Among them, reference Figures 1-3Multiple paint stripping blades 430 are rotatably mounted on a rotating head 420 around an output shaft 410 via a connecting shaft 440. The connecting shaft 440 passes through the rotating head 420 via bearings, and the multiple paint stripping blades 430 are located at the front end of the rotating head 420. Each of the multiple paint stripping blades 430 has a cutting edge 431 on one side close to each other, forming a paint stripping position 433 between the multiple cutting edges 431. Each connecting shaft 440 passes through the shaft hole of a driven gear 441, and each connecting shaft 440 is fixedly connected to the axis of a driven gear 441. Each driven gear 441 meshes with a driving gear 411, and the multiple driven gears 441 are arranged around the driving gear 411.

[0040] Among them, reference Figures 1-3 The driving gear 411 is used to drive the driven gear 441 to rotate on its own axis and revolve around the central axis. The rotation of the driven gear 441 drives the blade 431 of the paint stripping tool 430 to rotate inward, so that the blade 431 of at least one paint stripping tool 430 is close to the outer wall of the wire to be stripped and the paint is stripped from the outer wall of the wire to be stripped when the blade 431 of the paint stripping tool 430 revolves around the driving gear 411. Furthermore, the blade 431 of at least one paint stripping tool 430 can automatically follow the bending of the wire to be stripped and adaptively adjust its position by rotating.

[0041] Compared with the prior art, the above-mentioned one or more technical solutions in the automatic following paint stripper 400 provided in this utility model embodiment have at least one of the following technical effects:

[0042] Reference Figures 1-3During operation, the wire to be stripped of its coating, with the electromagnetic coil wound around it, is first inserted into the stripping position 433. Then, the output shaft 410 drives the drive gear 411 to rotate. The drive gear 411 drives the driven gear 441 to rotate first. The driven gear 441 drives the blade 431 of the stripping tool 430 to rotate inward through the connecting shaft 440, causing the blades 431 of multiple stripping tools 430 to move inward and at least one blade 431 to press against the outer wall of the wire to be stripped. At this time, the resistance of the wire to be stripped to the blade 431 causes the driven gear 441 to stop driving the blade 431 to rotate inward. The driven gear 441 then revolves around the drive gear 411 under the drive of the drive gear 411, so that the blade 431 of the stripping tool 430 strips the coating from the outer wall of the wire to be stripped. When stripping the coating from the bent portion of a wire, the cutting edge 431 of at least one stripping tool 430 can rotate outward around the connecting shaft 440 under the push of the bent portion of the wire, automatically adjusting its position to follow the bent portion of the wire to be stripped. Alternatively, the cutting edge of at least one stripping tool 430 can rotate inward around the connecting shaft 440 under the drive of the driving gear 411 and the driven gear 441, automatically adjusting its position to follow the bent portion of the wire to be stripped. This allows the cutting edge 431 of the stripping tool 430 to always remain in close contact with the outer wall of the wire to be stripped, effectively stripping the coating from the bent wire. Therefore, the automatic following stripping tool of this invention can strip the coating from bent wires without the need to straighten the wire before stripping, reducing the process of straightening the wire, lowering labor costs, and improving processing efficiency.

[0043] In another embodiment of this utility model, referring to Figures 1-3 The automatic following paint stripper 400 also includes multiple elastic reset members 450. Each elastic reset member 450 is connected at both ends to a connecting shaft 440 and a rotating head 420, respectively. The elastic reset member 450 has a reset force that drives the blade 431 of the paint stripper 430 to rotate outwards. Specifically, after the paint stripping of the wire is completed, the elastic reset member 450 elastically resets and drives the blade 431 of the paint stripper 430 to rotate outwards via the connecting shaft 440, causing the blades 431 of the multiple paint stripper blades 430 to open outwards, so that the stripped wire can be removed from the paint stripping position 433 or the next wire to be stripped can be inserted into the paint stripping position 433. Furthermore, the elastic reset member 450 has a spring force that drives the blade 431 of the paint stripper 430 to rotate outward, which can reduce part of the force that drives the blade 431 of the paint stripper 430 to rotate inward through the connecting shaft 440 via the driven gear 441. This prevents the blade 431 of the paint stripper 430 from pressing too hard against the outer wall of the wire to be stripped, so that the blade 431 of the paint stripper can smoothly revolve around the drive gear 411 to strip the paint from the outer wall of the wire to be stripped. The structure is reliable.

[0044] Furthermore, referring to Figures 1-3 Each connecting shaft 440 is provided with a connecting block 442, and both ends of each elastic reset member 450 are respectively connected to a connecting block 442 and a rotating head 420. Specifically, the connecting block 442 is fixedly connected to the connecting shaft 440 by screws for easy installation.

[0045] Furthermore, referring to Figures 1-3 Each connecting block 442 is provided with a first connecting member 443, and the rotating head 420 is provided with multiple second connecting members 423. The elastic reset member 450 is a tension spring, and the two ends of each tension spring are respectively sleeved on a first connecting member 443 and a second connecting member 423. Specifically, the first connecting member 443 and the second connecting member 423 are both bolts, and the first connecting member 443 and the second connecting member 423 are respectively screwed onto the connecting block 442 and the rotating head 420. The two ends of each tension spring are respectively sleeved on the bolt shank, and the bolt nut is larger than the tension spring's tension ring to prevent the tension ring from falling off the bolt shank.

[0046] Furthermore, referring to Figures 1-3 The outer wall of the rotating head 420 is evenly distributed with multiple receiving grooves 421, and multiple connecting blocks 442 are respectively housed in the multiple receiving grooves 421. The receiving groove 421 is provided with a first limiting platform 422. When the first limiting platform 422 abuts against the connecting block 442, it is used to limit the maximum angle of rotation of the blade 431 of the paint stripping tool 430 outward. That is, the elastic reset member 450 elastically resets and drives the blade 431 of the paint stripping tool 430 to rotate outward through the connecting shaft 440, so that the blades 431 of the multiple paint stripping tools 430 are opened to the maximum position outward.

[0047] Furthermore, referring to Figures 1-3 The outer wall of the rotating head 420 is evenly distributed with multiple receiving grooves 421, and multiple connecting blocks 442 are respectively housed in the multiple receiving grooves 421. The rotating head 420 is provided with a second limiting platform 461 on one side of the receiving groove 421. When the second limiting platform 461 abuts against the connecting block 442, it is used to limit the maximum angle of inward rotation of the blade 431 of the paint stripping knife 430, preventing the blade 431 of the paint stripping knife 430 from pressing too hard against the outer wall of the wire to be stripped, so that the blade 431 of the paint stripping knife can smoothly revolve around the drive gear 411 to strip the paint from the outer wall of the wire to be stripped, and the structure is reliable.

[0048] Furthermore, referring to Figures 1-3The rotating head 420 is rotatably fitted with a limiting ring 460, which has multiple limiting grooves 462. One end of each of the multiple connecting blocks 442 extends into one of the limiting grooves 462. One wall of each limiting groove 462 serves as a second limiting platform 461. The limiting ring 460 has at least one fastener (not shown in the figure) for locking or loosening the limiting ring 460. Specifically, loosening the fastener releases the limiting ring 460, allowing the limiting ring 460 to rotate and adjust the position of the second limiting platform 461. This adjusts the maximum inward rotation angle of the blade 431 of the paint stripping tool 430, making it suitable for stripping paint from thinner wires. After adjusting the second limiting platform 461 to a suitable position, tightening the fastener locks the limiting ring 460 onto the rotating head 420.

[0049] Furthermore, referring to Figures 1-3 The fastener is a fastening screw. The outer wall of the second limiting platform 461 is provided with a threaded hole 463 that connects to the rotating head 420. The fastening screw is screwed into it. By tightening the fastening screw to press the rotating head 420, the limiting ring 460 can be locked onto the rotating head 420. The structure is simple.

[0050] Furthermore, referring to Figure 6 The rotating head 420 has a protective cover 470 at its front end, which covers multiple paint stripping blades 430. The front end of the protective cover 470 has a wire insertion hole 471 that faces the paint stripping position 433. The wire to be stripped, which is wound with an electromagnetic coil, is inserted into the paint stripping position 433 through the wire insertion hole 471. When the blade 431 of the paint stripping blade 430 strips the paint from the outer wall of the wire to be stripped, the protective cover 470 blocks the paint stripping debris to prevent it from splashing outside.

[0051] Furthermore, referring to Figures 1-3 Each paint stripper 430 is mounted on a tool holder 432. Specifically, the paint stripper 430 is fixed to the tool holder 432 with screws for easy installation. Multiple tool holders 432 are respectively mounted on one end of multiple connecting shafts 440. Specifically, the tool holders 432 are fixed to one end of the connecting shafts 440 with screws for easy installation.

[0052] Furthermore, referring to Figure 3 The rotating head 420 has a first connecting hole 424 through its center, and the output shaft 410 passes through the first connecting hole 424, so that the rotating head 420 is rotatably mounted outside the output shaft 410, resulting in a simple structure. The rotating head 420 has multiple second connecting holes 425 passing through it around the first connecting hole 424, and multiple connecting shafts 440 are rotatably mounted through the multiple second connecting holes 425 via bearings, so that the connecting shafts 440 are rotatably connected to the rotating head 420, resulting in a simple structure.

[0053] Furthermore, referring to Figures 1-3The rotating head 420 is provided with a receiving cavity 426, in which the driving gear 411 and multiple driven gears 441 are all housed, resulting in a compact structure.

[0054] In another embodiment of this utility model, referring to Figures 4-6 Furthermore, a paint stripper is provided, including a frame 100, a horizontal moving mechanism 200 disposed on the frame 100, a drive mechanism 300 disposed on the horizontal moving mechanism 200, and the aforementioned automatic following paint stripper 400 disposed on the drive mechanism 300; the drive mechanism 300 is connected to the other end of the output shaft 410 of the automatic following paint stripper 400 and is used to drive the output shaft 410 to rotate. Specifically, refer to... Figure 3 and Figure 6 The output shaft 410 is driven to rotate by the drive mechanism 300, which in turn drives the drive gear 411 to rotate. The drive gear 411 drives the driven gear 441 to rotate first. The driven gear 441 drives the blade 431 of the paint stripping tool 430 to rotate inward through the connecting shaft 440, causing the blades 431 of multiple paint stripping tools 430 to move inward and at least one of the paint stripping tools 430 to press against the outer wall of the wire to be stripped. At this time, the obstruction of the blade 431 by the wire to be stripped causes the driven gear 441 to stop driving the blade 431 to rotate inward. The driven gear 441 then revolves around the drive gear 411 under the drive of the drive gear 411, so that the blade 431 of the paint stripping tool 430 strips the paint from the outer wall of the wire to be stripped. Then, the horizontal moving mechanism 200 drives the automatic following paint stripper 400 to move horizontally along the length of the wire to be stripped to its end, thereby driving the cutting edge 431 of the paint stripper 430 to move horizontally along the length of the wire to be stripped to its end, so as to strip the paint from the outer wall of the wire section. There is no need to manually move the wire to be stripped, saving labor costs and improving processing efficiency.

[0055] Furthermore, referring to Figure 5 and Figure 6 The horizontal moving mechanism 200 includes linear guide rails 210, a moving platform 220, and a first driving member 230. Two linear guide rails 210 are symmetrically mounted on the frame 100 via a mounting base 212. Each linear guide rail 210 is slidably connected to at least one slider 211. The moving platform 220 is fixed to the slider 211 and has a vertical plate 221. The driving mechanism 300 is mounted on the vertical plate 221. The first driving member 230 is mounted on the frame 100 and connected to the moving platform 220 to drive the moving platform 220 to move horizontally along the linear guide rails 210, thereby causing the blade 431 of the paint stripping tool 430 to move horizontally along the length of the wire to be stripped towards its end.

[0056] The first driving component 230 can be a telescopic cylinder, an electric cylinder, or a rodless cylinder, etc., and is not limited here.

[0057] Furthermore, referring to Figure 5 and Figure 6 The drive mechanism 300 includes a second drive member 310, a transmission assembly 320, and a drive shaft 330. The drive shaft 330 is rotatably mounted on the vertical plate 221 via bearings. One end of the drive shaft 330 movably passes through the rotating head 420 and is fixedly connected to the other end of the output shaft 410. The second drive member 310 is mounted on the vertical plate 221 and is connected to the other end of the drive shaft 330 via the transmission assembly 320 to drive the drive shaft 330 to rotate, thereby driving the output shaft 410 to rotate.

[0058] Furthermore, referring to Figure 5 and Figure 6 The second driving component 310 is a motor, and the transmission assembly 320 includes two transmission wheels 321 and a transmission belt (not shown). The centers of the two transmission wheels 321 are respectively located on the motor shaft and the other end of the drive shaft 330. The transmission belt is adapted to be mounted on the two transmission wheels 321. The motor drives the drive shaft 330 to rotate through the transmission wheels 321 and the transmission belt, thereby driving the output shaft 410 to rotate. The structure is simple. The transmission wheels 321 can be synchronous pulleys or sprockets, and the transmission belt can be a synchronous belt or a chain. When the transmission wheel 321 is a synchronous pulley, the transmission belt is a synchronous belt. When the transmission wheel 321 is a sprocket, the transmission belt is a chain.

[0059] Among them, reference Figure 4 The paint stripper includes an electrical control device 110, a horizontal moving mechanism 200, and a drive mechanism 300, all electrically connected to the electrical control device 110. In this embodiment, the electrical control device 110 can be configured using a PLC or an integrated chip according to actual production needs. Since the electrical control device 110 is a mature and established technology, how it controls the paint stripper should be well-known and mastered by those skilled in the art. Therefore, its control principle will not be described in detail here.

[0060] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0061] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
