Description

Technical Field

[0001] The utility model relates to a coiling forming device, in particular to an electric heating wire coiling forming device. Background Art

[0002] An electric heating wire refers to a thin wire made of a conductor material, which generates heat energy by being electrically heated, and is a core component of many electrical appliances such as electronic cigarettes, hair dryers, and heaters. After the electric heating wire is energized, the current passes through the surface conductor, and after passing through a certain resistance, the electrical energy is converted into heat energy, thereby increasing the temperature of the wire. As the temperature of the wire increases, thermal radiation is emitted from its surface, thereby heating the surrounding objects.

[0003] Generally speaking, the electric heating wire needs to be wound into a spiral shape for use. When winding, attention needs to be paid to the material and specifications of the wire material, the density and spacing of the winding, the winding direction, and the neatness of the winding, etc. Only by winding the electric heating wire carefully and precisely can the normal operation of the hair dryer and the safe use of the user be ensured. Common methods for winding electric heating wires include winding with a winding machine and manual winding.

[0004] The winding machine winds the electric heating wire by rotating the rotating shaft, and controls the displacement of the electric heating wire during the winding process to wind it into a spiral shape. The diameter of the rotating shaft is the diameter of the spiral of the electric heating wire. In real life, due to the wide application of electric heating wires, the sizes of the spiral electric heating wires used in different scenarios are different. During processing, different-sized rotating shafts need to be prepared, and the sizes of the rotating shafts on the market are non-linearly continuous. In special cases, a rotating shaft with a specific size even needs to be additionally processed to meet the production requirements, which greatly increases the production cost.

[0009] A rotating mechanism is arranged on the chassis, and the rotating mechanism can drive the arc-shaped plate to rotate so as to wind the electric heating wire on the arc-shaped plate;

[0010] A coiling mechanism is provided on the chassis. When the rotating mechanism operates, the coiling mechanism can drive the wire wheel and the coil wheel to displace synchronously, and the displacement direction is parallel to the length direction of the arc-shaped plate, so that the electric heating wire can be spirally wound on the arc-shaped plate.

[0011] A diameter-changing mechanism is further provided on the chassis. The diameter-changing mechanism can drive the arc-shaped plate to displace, so that the arc-shaped plates are relatively close to or relatively far from each other, thereby changing the diameter of the formed spiral electric heating wire.

[0015] For the electric heating wire spiral forming device as described above: The diameter-changing mechanism includes a diameter-changing motor installed on the chassis.

[0017] For the electric heating wire spiral forming device as described above: A connecting plate is installed at the lowermost end of the chassis, and a plurality of groups of connecting holes are opened on the connecting plate.

[0018] The electric heating wire coiling and forming device as described above: A bearing platform that cooperates with the spool is provided on the chassis, and the bearing platform can restrict the spool when the coil wheel displaces.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows: Through the mutual cooperation of the rotating mechanism and the coiling mechanism, the electric heating wire can be coiled in a spiral shape on the arc-shaped plate, that is, the electric heating wire can be processed into a spiral shape; By changing the distance between the arc-shaped plate and the axis of the coiling shaft through the diameter-changing mechanism, the spiral diameter of the spiral-shaped electric heating wire processed by the rotating mechanism and the coiling mechanism can be controlled. Since it is controlled by thread fit, the variation range of the product diameter is linearly continuously distributed, so the production cost of preparing the rotating shaft and the processing rotating shaft is reduced; Since the diameter-changing process is completed through the thread fit of the lead screw and the internal thread sleeve, the product size is fixed after the diameter change and will not be changed by external interference; Since the displacement of the wire guide sleeve is realized through the thread fit of the thread protrusion and the wire guide sleeve, the displacement speed of the wire guide sleeve is fixed, that is, the pitch of the coiled spiral-shaped electric heating wire is also fixed.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0036] Please refer to Figures 1 to 7 , as an embodiment of the present invention, the electric heating wire coiling and forming device includes a chassis 1 and a coil wheel 602 provided on the chassis 1;

[0037] A plurality of arc plates 404 are provided on the chassis 1, and the plurality of arc plates 404 are evenly distributed in a circumferential manner; a wire guide wheel 303 is also provided on the chassis 1;

[0038] A rotating mechanism is provided on the chassis 1, and the rotating mechanism can drive the arc plate 404 to rotate so as to wind the electric heating wire around the arc plate 404;

[0039] A coiling mechanism is provided on the chassis 1, and the coiling mechanism can drive the wire guide wheel 303 and the coil wheel 602 to synchronously displace when the rotating mechanism acts, and the displacement direction is parallel to the synchronous direction of the arc plate 404; so that the electric heating wire can be spirally wound around the arc plate 404;

[0040] A diameter-changing mechanism is further provided on the chassis 1, and the diameter-changing mechanism can drive the arc plate 404 to displace, so that the arc plates 404 are relatively close to or relatively far from each other to change the diameter of the formed electric heating wire coil.

[0041] In this embodiment, first fix the original coil of the electric heating wire on the coil wheel 602, then pass the electric heating wire through the wire guide wheel 303, and finally fix the electric heating wire on the arc plate 404;

[0042] Drive the arc-shaped plate 404 to rotate through the rotating mechanism, so as to wind the electric heating wire on the coil wheel 602 around the arc-shaped plate 404. By rotating multiple groups of arc-shaped plates 404 to wind the coil, the electric heating wire on the coil wheel 602 can be wound quickly. Drive the wire wheel 303 and the coil wheel 602 to displace synchronously through the coiling mechanism to change the position where the electric heating wire is wound on the arc-shaped plate 404. Since the position of the electric heating wire changes, the winding angle will also change accordingly, so that the electric heating wire can be coiled around the arc-shaped plate 404; Since the rotating mechanism and the coiling mechanism act synchronously, the coiled electric heating wire is in a spiral shape. The diameter of the circle with the arc-shaped plates 404 circumferentially and equally spaced between multiple groups is the diameter of the spiral electric heating wire.

[0043] Drive the arc-shaped plate 404 to move relatively closer or farther away through the diameter-changing mechanism, so that the diameter of the circle with the arc-shaped plates 404 circumferentially and equally spaced between multiple groups decreases or increases. When the diameter decreases or increases, the diameter of the coiled spiral electric heating wire also decreases or increases.

[0044] Drive the arc-shaped plate 404 to displace through the diameter-changing mechanism, so as to change the diameter of the coiled spiral electric heating wire, and the size of the electric heating wire that can be produced can be increased without replacing the device or parts. Through the mutual cooperation of the rotating mechanism and the coiling mechanism, the electric heating wire that meets the design requirements can be produced quickly and accurately.

[0045] As a further solution of the present invention, the rotating mechanism includes a coiling motor 2 installed on the chassis 1. A wire shaft 3 is installed at the output end of the coiling motor 2, and the wire shaft 3 is rotatably installed on the chassis 1; A coiling shaft 4 is rotatably installed on the chassis 1, and the coiling shaft 4 is connected to the wire shaft 3 through a belt 8; A connecting rod 405 is rotatably installed on the arc-shaped plate 404, and the end of the connecting rod 405 away from the arc-shaped plate 404 is rotatably installed on the coiling shaft 4.

[0046] In this embodiment, when the coiling motor 2 is started, the wire shaft 3 will rotate, and at the same time drive the coiling shaft 4 to rotate through the belt 8, and the coiling shaft 4 will drive the arc-shaped plate 404 to rotate around the axis of the coiling shaft 4 through the connecting rod 405, so as to wind the electric heating wire on the coil wheel 602 around the arc-shaped plate 404. The distance from the vertex of the outer arc of the arc-shaped plate 404 to the axis of the coiling shaft 4 is the radius of the innermost coil after the electric heating wire is wound. If there is no other mechanism to cooperate, the wound electric heating wire will be in a vortex shape or be wound messily on the arc-shaped plate 404.

[0047] As a further solution of the present utility model, the coiling mechanism includes a thread projection 302 installed on the wire shaft 3, and a wire sleeve 301 is threadedly connected to the thread projection 302; the wire wheel 303 is rotatably installed on the wire sleeve 301;

[0048] The coiling mechanism further includes a spool 6 hinged to the chassis 1, a sliding sleeve 601 is movably installed on the spool 6, the sliding sleeve 601 is connected to the wire sleeve 301, and the coil wheel 602 is rotatably installed on the sliding sleeve 601.

[0049] In this embodiment, when the coiling motor 2 drives the wire shaft 3 to rotate, the thread projection 302 drives the wire sleeve 301 to displace through threaded connection, and its displacement direction is the length direction of the wire shaft 3. When the wire sleeve 301 displaces, it will drive the wire wheel 303 to displace, and at the same time it will also drive the sliding sleeve 601 to displace. Therefore, the coil wheel 602 also displaces synchronously. Through the synchronous displacement of the wire wheel 303 and the coil wheel 602, the position where the electric heating wire is wound on the arc plate 404 changes under the action of the rotating mechanism, so that the electric heating wire will be spirally wound on the arc plate 404; that is, under the mutual cooperation of the rotating mechanism and the coiling mechanism, the electric heating wire will be tightly and spirally wound on the arc plate 404. When the length of the spiral electric heating wire meets the design requirements, cut off the electric heating wire and remove the finished product, and then fix the electric heating wire on the arc plate 404 again to process the next product.

[0050] Since the displacement of the wire sleeve 301 is realized by the threaded cooperation between the thread projection 302 and the wire sleeve 301, the displacement speed of the wire sleeve 301 is fixed, that is, the pitch of the spirally wound electric heating wire is also fixed.

[0051] As a further solution of the present utility model, the diameter-changing mechanism includes a diameter-changing motor 7 installed on the chassis 1, the output end of the diameter-changing motor 7 is connected to a lead screw 5, and the lead screw 5 is rotatably installed on the chassis 1; an internally threaded sleeve 501 is threadedly connected to the lead screw 5; a coiling sleeve 401 connected to the internally threaded sleeve 501 is movably installed on the coiling shaft 4, and a turntable 402 is rotatably installed on the coiling sleeve 401.

[0052] In this embodiment, when the design requirements change, the variable-diameter motor 7 can be started. The variable-diameter motor 7 drives the lead screw 5 to rotate, and through the thread fit, the internal thread sleeve 501 is displaced in the length direction of the lead screw 5, thereby driving the coiling sleeve 401 to be displaced in the length direction of the coiling shaft 4; so that the turntable 402 approaches or moves away from the variable-diameter motor 7. Since the displacement of the turntable 402 is completed through the thread fit between the lead screw 5 and the internal thread sleeve 501, when the variable-diameter motor 7 stops rotating, the position of the turntable 402 will not change due to external interference, enabling the variable-diameter mechanism to stably maintain the distance between the arc-shaped plate 404 and the axis of the coiling shaft 4, so that the finished product meets the design requirements.

[0053] As a further solution of the present invention, the variable-diameter mechanism further includes a plurality of groups of sliding grooves 403 opened on the turntable 402. Each sliding groove 403 corresponds to one arc-shaped plate 404, and a protruding block 406 connected to the arc-shaped plate 404 is slidably fitted in the sliding groove 403; a connecting rod 405 is rotatably installed on the arc-shaped plate 404, and the end of the connecting rod 405 away from the arc-shaped plate 404 is rotatably installed on the coiling shaft 4.

[0054] In this embodiment, when the turntable 402 moves away from the variable-diameter motor 7, the protruding block 406 will slide outwards in the sliding groove 403, thereby increasing the angle between the connecting rod 405 and the coiling shaft 4, and increasing the distance between the arc-shaped plate 404 and the axis of the coiling shaft 4 by increasing the angle. When the turntable 402 approaches the variable-diameter motor 7, the protruding block 406 will slide inwards in the sliding groove 403, thereby reducing the angle between the connecting rod 405 and the coiling shaft 4, and reducing the distance between the arc-shaped plate 404 and the axis of the coiling shaft 4 by reducing the angle.

[0055] Control the rotation direction of the variable-diameter motor 7 according to the design requirements, so that the turntable 402 approaches or moves away from the variable-diameter motor 7, to reduce or increase the distance between the arc-shaped plate 404 and the axis of the coiling shaft 4, so that the processed electric heating wire meets various design requirements.

[0056] As a further solution of the present invention, a connecting plate is installed at the lowermost end of the chassis 1, and a plurality of groups of connection holes are opened on the connecting plate.

[0057] In this embodiment, the device is fixed on the workbench through the connection holes, so that the whole device can work stably. It is also convenient to disassemble the device from the workbench and transfer it to other places.

[0058] As a further solution of the present invention, a bearing platform that cooperates with the spool 6 is provided on the chassis 1, and the bearing platform can limit the spool 6 when the coil wheel 602 is displaced.

[0059] In this embodiment, when the rotating mechanism and the coiling mechanism are working, the rotation of the arc-shaped plate 404 will give the coil wheel 602 the power of displacement through the electric heating wire, thereby driving the displacement of the spool 6, and the displacement of the spool 6 is offset by restricting the displacement of the spool 6 through the bearing platform; alternatively, when the electric heating wire on the coil wheel 602 is consumed, a new electric heating wire coil can be replaced by restricting the spool 6 through the contact bearing platform.

[0060] The above embodiments are exemplary rather than restrictive. Therefore, without departing from the spirit or basic characteristics of the present invention, all technical solutions that can implement the present invention in other specific forms are included in the present invention.
