Description

Technical Field

[0001] The present invention relates to a forming device, and in particular to a heating wire forming device. Background Art

[0002] A hair dryer is formed by combining a set of heating wires and a high-speed small fan. When powered on, the heating wires generate heat, and the air blown by the fan passes through the heating wires and is blown out to form hot air. Among the accessories of the hair dryer, the heating wire is the core component of the entire hair dryer. The longer the heating wire accommodated in a unit space, the better the blowing effect of the hair dryer. The waveform of the heating wire is the main factor affecting the length of the heating wire accommodated in a unit space. Therefore, the processing and forming of the heating wire is extremely important for the quality of the hair dryer product, and the device for processing the heating wire is the key equipment affecting the quality and production cost of the hair dryer. The existing waveform height of the heating wire is 3.0 - 4.0 mm, and the width is 4.5 - 6.0 mm. On the one hand, because the waveform is relatively flat, the heating wire accommodated in a unit space is limited. In order for the manufacturer to achieve the required length of the heating wire for the hair dryer, the space for heating and winding will be increased, resulting in the inability to reduce the external shape of the product. On the other hand, because the waveform is relatively flat, the mica plate can only be set as a hollow cylinder or frustum of a cone in the middle for smooth winding, and the stepped winding method cannot be carried out, resulting in the loss of a part of the heat when the heating wire is working, and the air blown out by the hair dryer cannot be heated to the greatest extent. Therefore, improvements are needed. Summary of the Invention

[0003] Aiming at the defects in the prior art that the waveform of the processed and formed heating wire is flat, resulting in a large winding space for the heating wire and low heating efficiency, etc., the present invention provides a new heating wire forming device.

[0032] Embodiment 1

[0033] A heating wire forming device includes a bracket 1, and further includes at least 2 sets of forming gear sets 2, a driving unit 5, and an adjusting assembly 3.

[0034] The forming gear sets 2 are arranged along the bracket 1 to extrude the heating wire passing through in sequence, realizing the step-by-step adjustment of the heating wire. The central positions of the meshing areas 23 of the forming gear sets 2 are on a vertical straight line, so that when the heating wire is formed, its waveform will not generate additional deformation. The number of the forming gear sets 2 can be specifically set according to the waveform of the heating wire, and can be 3 sets, 4 sets, 5 sets, 6 sets, etc.

[0035] During use, the driving unit 5 is started, and the driving gear 22 is driven by the driving unit 5 to rotate. The driving gear 22 rotates synchronously with the adjusting gear 21 to process the heating wire in the meshing area 23. The heating wire passes through the forming gear set 2 in sequence, realizing the step-by-step adjustment of the heating wire, increasing the maximum height of the heating wire waveform and reducing the minimum width of the heating wire waveform, making the slope of the heating wire waveform steeper, so that the length of the heating wire in the unit space is longer. During the processing of the hair dryer, the stepped winding of the heating wire can be realized, thereby improving the working efficiency and heating effect of the heating wire, and being more conducive to the miniaturization of the hair dryer volume.

[0036] Preferably, the centers of the meshing areas 23 of the forming gear set 2 are located on the same straight line.

[0037] Preferably, the driving gear 22 and the adjusting gear 21 of the same forming gear set 2 have the same number of teeth and module.

[0038] Preferably, the radii of the driving gear 22 and the adjusting gear 21 gradually increase or decrease from top to bottom.

[0039] Preferably, the adjusting assembly 3 includes a base block 31, a left-right adjusting bolt 33, and a front-back adjusting bolt 32. The adjusting gear 21, the left-right adjusting bolt 33, and the front-back adjusting bolt 32 are arranged on the base block 31. The left-right adjusting bolt 33 and the front-back adjusting bolt 32 are connected to the bracket 1 and support the base block 31. The central axis of the left-right adjusting bolt 33 is distributed along the left-right direction of the bracket 1, and the central axis of the front-back adjusting bolt 32 is distributed along the front-back direction of the bracket 1.

[0040] Preferably, a limiting assembly 7 is further included. The limiting assembly 7 includes a first limiting block 71, a second limiting block 72, and a third limiting block 73. The first limiting block 71 is arranged on the bracket 1 and above the uppermost forming gear set 2. The third limiting block 73 is arranged on the bracket 1 and below the lowermost forming gear set 2. The second limiting block 72 is arranged on the bracket 1 and between two adjacent forming gear sets 2.

[0041] Preferably, wire grooves 74 are arranged on the first limiting block 71, the second limiting block 72, and the third limiting block 73, and the wire grooves 74 are located in the same vertical plane.

[0042] Preferably, the driving unit 5 includes a connecting gear set 51 and a motor 52. The connecting gear set 51 includes a first connecting gear 511, a second connecting gear 512, a third connecting gear 513, and a connecting shaft set 4. The motor 52 is connected to the first connecting gear 511. The first connecting gear 511 is connected to the second connecting gear 512 through the third connecting gear 513. The second connecting gear 512 is connected to the driving gear 22 through the connecting shaft set 4.

[0043] Preferably, the connecting gear set 51 further includes a fourth connecting gear 514. The fourth connecting gear 514 meshes with the second connecting gear 512. The fourth connecting gear 514 is connected to the adjusting gear 21 through the connecting shaft set 4.

[0044] Preferably, a positioning wheel 6 is further included. The positioning wheel 6 is arranged on the bracket 1.

[0045] Specifically, the driving gears 22 and the adjusting gears 21 of the same forming gear set 2 are of equal size. For different forming gear sets 2, the driving gears 22 and the adjusting gears 21 of the forming gear set 2 at the bottom are the largest, and the driving gears 22 and the adjusting gears 21 of the forming gear set 2 at the top are the smallest. The connecting gear set 51 drives the driving gear 22 and the adjusting gear 21 through the motor 52. Specifically, the driving gear 22 and the second connecting gear 512 are located at both ends of the connecting shaft set 4. The first connecting gear 511 is connected to the motor 52. The second connecting gear 512 meshes with the first connecting gear 511. The number of the second connecting gears 512 is determined according to the number of the forming gear sets 2. The third connecting gear 513 is used to connect the first connecting gear 511, the second connecting gear 512, and the fourth connecting gear 514. The third connecting gear 513 is used to transmit the driving force of the first connecting gear 511, so that the second connecting gear 512 and the fourth connecting gear 514 rotate smoothly. The number of the third connecting gears 513 is determined according to the actual use situation.

[0046] During use, the motor 52 is started. The motor 52 drives the driving gear 22 to rotate. Since the driving gear 22 and the adjusting gear 21 are in a meshing state, when the driving gear 22 rotates, the adjusting gear 21 rotates synchronously with the driving gear 22. After being guided by the positioning wheel 6, the heating wire enters the wire groove 74 of the third limiting block 73, and then enters the first forming gear set 2. The first forming gear set 2 shapes the heating wire into a shape similar to the preset waveform. Then, the preliminarily shaped heating wire enters the second and third forming gear sets 2 for continuous two-time shaping, so that the waveform of the heating wire continuously approaches the preset waveform. Then, it enters the last forming gear set 2 for final shaping to complete the processing of the waveform of the heating wire.
