One type is a hard knife rotary squeegee method (usually used for 26 AWG thick wire with a wire diameter of 0.4 m/m or more), and another One type is the use of soft nylon fiber stripping strip stripping method (usually used for fine lines below US A26AWG). Such machines are represented by the products of US CARPENTER MFG. CO., INC. (MAGNET WIRE STRIPPERS MODEL 88E). The basic patents it owns were authorized in 1959 (US Patents 2902797), and current domestic and foreign manufacturers' counterfeits are based on this. The structure and working principle of the above prototype machine are as follows: As shown in Fig. la-lc, the motor 1 drives the transmission wheel 2, and the paint removing rings 8 and 9 on the transmission components 5 and 6 are opposite directions via the transmission rubber rings 3 and 4, respectively. Rotate, using the friction between the paint strip and the enameled wire to remove the varnish surface varnish. After the motor 1 is rotated, the pressure adjusting screw 7 (with the buffer spring 21 thereon) is used to adjust the contact surface pressure between the stripping rollers according to the diameter of the enameled wire to be stripped, and the enameled wire is placed from the top of the two stripping rollers, and then Pull back and let the enameled wire pass between the two paint strip contact surfaces. Since it only grinds (off) the two sides of the enameled wire at a time, it is necessary to rotate the enameled wire by 90 degrees and then grind (off) the other two sides to completely remove the varnish on the surface of the enameled wire.

detailed description

In order to make the objects, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. The specific embodiments described herein are merely illustrative of the invention, but are not intended to limit the invention. It should be noted that the same structural elements are denoted by the same reference numerals in the drawings attached to the drawings, and a part of the structural parts are omitted in the drawings.

The invention provides an enameled wire stripper, comprising an electric motor, a transmission wheel, two transmission aprons, two transmission components, two stripping rollers, and an offset component, wherein the transmission component has a rotating shaft, and the motor drive connection transmission The wheel, the transmission wheel drives the rotating shaft of the transmission assembly through the driving apron; at least two stripping rollers are respectively fixed on the rotating shaft, and the stripping rollers are arranged close to each other to frictionally pass between the contact faces of the stripping rollers The enameled wire is connected to the rotating shaft, and the paint removing wheel is relatively moved by the rotating shaft along the tangential direction of the contact surface of the paint removing wheel, and the relative moving distance is greater than or equal to 1/4 of the circumferential length of the enameled wire cross section. The enameled wire stripper of the present invention comprises an electric motor, a transmission wheel, two transmission aprons, two transmission components, two stripping rollers, and an offset assembly, wherein the transmission assembly has a rotating shaft; the motor drives the transmission wheel to run at a high speed, and the transmission The wheel drives the rotating shaft of the transmission component through the driving rubber ring, thereby driving the paint removing wheel on the rotating shaft to rotate at a high speed, and the two stripping paint wheels are pressed close to each other to rotate in opposite directions, and the offset component makes the stripping paint wheel tangentially along the contact surface. Reciprocating high-speed motion (the movement in the direction of the arrow as shown in Figure 2) causes the enameled wire to be shaken between the two paint strips, rapidly changing the position of the contact point where the enameled wire is ground (off), and the tangential direction between the paint strips The displacement of the mutual movement is greater than or equal to 1/4 of the circumference of the enameled wire cross section, thereby realizing the entire circumferential surface of the friction enameled wire, completing the stripping work of the enameled wire at one time, and ensuring the clean and tidy interface of the stripping paint. The practical use effect of the enameled wire stripper of the invention is very obvious, and the multiple strips can be simultaneously stripped at one time, and the stripping interface is clean and tidy.

Since the enameled wire is very thin and the cross-sectional diameter is very small, the actual displacement between the two paint strips is very small, usually 0.5-1.0 mm. In practical applications, the offset assembly may include a ball bearing disposed on the rotating shaft, wherein a gap of the ball groove of the ball bearing is larger than a diameter of the ball, so that the inner casings of the ball bearing can move relative to each other in the axial direction; the offset component further includes The eccentric block is disposed on the transmission wheel corresponding to the working position of the transmission apron.

Further, as shown in FIGS. 3a-3c, the offset assembly of the present invention may adopt the following embodiments: Replace four identical standard ball bearings in the transmission components 5 and 6 of the prior art enameled wire stripper into one Non-standard special ball bearing 11. In addition to relative rotation between the inner casings of the bearing, it can also move relative to each other in the axial direction, which is achieved by increasing the gap between the ball grooves. Then, an eccentric block 17 and 18 are respectively arranged at a working error of 180 degrees at the working position of the driving apron at both ends of the driving wheel 2. When the driving wheel rotates at a high speed, the eccentric block will cause the driving apron to shake, and the two circles have opposite directions of shaking, thereby driving The paint strips 8 and 9 on the drive assemblies 5 and 6 are also rotated in opposite directions while also acting as a mutual tilt between the two axial wheels. By adopting the above embodiment, the present invention can achieve a better paint stripping effect.

As an optional embodiment, the offset assembly of the present invention may include a ball bearing disposed on the rotating shaft, wherein a gap of the ball groove of the ball bearing is larger than a diameter of the ball, so that the inner casings of the ball bearing can move relative to each other in the axial direction; The offset assembly may further include a follower magnet disposed at the bottom of the rotating shaft, and a fixed magnet corresponding to the rotating magnet disposed on the base of the enameled wire stripper.

This embodiment differs from the above embodiment in that the eccentric blocks 17 and 18 are not provided at the transmission wheel 2 as shown in FIGS. 3a-3c, but the upper and lower standards in any of the components of the transmission assembly 5 or 6. Axis The bearing is replaced with the above-mentioned non-standard special bearing 11, a permanent magnet 12 is placed under the rotating shaft 19 or 20, and a permanent magnet 13 is arranged at the lower base of the corresponding permanent magnet 12. When the rotating shaft 19 or 20 rotates, the use of the permanent The principle of homosexual reciprocal between the magnets pushes the reciprocating high-speed movement of the rotating shaft 19 or 20 in the axial direction, thereby achieving the purpose of squeezing the enameled wire. If the permanent magnet is not used, it can also be replaced by an electromagnetic coil. (This embodiment uses the principle of the same-sex repelling of the magnet. By design, when the rotating shaft is pushed by the repulsive force, the stripping roller tends to be below the rotating shaft. Conversely, the magnet can be sucked by the opposite sex. Implementation.). It should be noted that the present invention adopts a permanent magnet disposed on any of the transmission components and the corresponding position of the base. However, those skilled in the art can easily think of the embodiment in which the two sets of transmission components and the base are provided with permanent magnets. . In such an embodiment, it should be noted that when the permanent magnets are installed, it is necessary to ensure that the rotating shafts of the two sets of transmission components do not move in the same direction in the axial direction at the same time to ensure the relative movement of the paint strip. And to ensure that the relative movement displacement is greater than or equal to the 1/4 circumference length of the cross section of the enameled wire. As another optional embodiment, the transmission assembly may be configured to be respectively rotatable about a fixed fulcrum, the offset assembly may be an eccentric block disposed at an upper portion or a lower portion of a rotating shaft, or the offset assembly may include an upper portion disposed on a rotating shaft Or the lower follower magnet and the magnet placed on the base of the enameled wire stripper. As shown in Fig. 4, without replacing the bearing and setting the eccentric blocks 17, 18 on the transmission wheel 2 and providing the permanent magnets 12, 13, it is only possible to change the transmission components 5 and 6 to each of them with their fulcrums A and B as the center.

Wherein, the eccentric block 16 can be replaced by a permanent magnet or an electromagnetic coil 14, and is disposed at a lower portion or an upper portion of the rotating shaft, and a permanent magnet or an electromagnetic coil 15 is disposed at a corresponding position of the base, and the isotropic phase repelling principle is used to drive the transmission component by the same principle. 5 and 6 also make the synchronous swing to the left and right while rotating the shaft, so as to achieve the purpose of squeezing the enameled wire. In order to keep the two paint rollers oscillating left and right, the pressure between the two is stable, and a pressure regulating assembly 22 can be added between the two transmission components 5 and 6. A spring member is preferably employed as the pressure regulating assembly 22. In addition, it is also possible to prevent the permanent magnets or the electromagnetic coils 14 and 15 from colliding with each other when sucked, for example, a support spring is disposed above the other side transmission assembly provided with the permanent magnet or the electromagnetic coil 14 (in the figure) Not shown).

In addition, in accordance with the enamelled wire stripper of the present invention, the present invention also provides a method for stripping paint for an enameled wire using an enameled wire stripper, the enamelled wire stripper having two stripping rollers adjacent to each other, the stripping roller respectively Set on the rotating shaft of the two transmission components, when the enameled wire stripping paint wheel rotates in the opposite direction with the rotating shaft, the offset component is used to relatively move the stripping paint wheel along the tangential direction of the contact surface of the paint stripper, and the moving distance is greater than Equal to the 1/4 circumference length of the enameled wire cross section. The method corresponds to the working principle of the stripper of the present invention. Therefore, it can realize the entire circumferential surface of the friction enameled wire, complete the stripping work of the enameled wire at one time, and ensure the clean and tidy interface of the stripping paint. The actual use effect of the enameled wire stripper of the invention is very obvious, and the multiple strips can be simultaneously stripped at one time, and the stripping interface is clean and tidy.

As a further preference, the offset component used in the method can be configured as the offset component as described above in the present invention.

Additionally, in accordance with other configurations of the foregoing enamelled wire stripper of the present invention, the method can include the use of pressure regulating assembly 22 to control the synchronized swing and pressure between the paint strips. A support spring can also be used to control the amount of swing of the drive assembly.
