Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] A wire heating and straightening device, see [link / reference] Figures 1-9 It includes a housing 100 and a heating mechanism 200 and a straightening mechanism 300 disposed within the housing 100.

[0019] The outer casing 100 includes a housing 110 and a top cover 120 hinged to the housing 110. The top space of the housing 110 is a straightening space, and the heating mechanism 200 is installed within the straightening space. The heating mechanism 200 includes a heating lamp 210 and a cover 220. The heating lamp 210 is installed at the bottom of the straightening space and heats up when powered on. The cover 220 covers the heating lamp 210 to prevent wires or foreign objects from directly contacting the heating lamp 210. The cover 220 has heat dissipation holes 221 to dissipate heat. The straightening mechanism 300 is installed within the straightening space above the cover 220.

[0020] The housing 110 has a row of inlet holes 111 and a row of outlet holes 112 on both sides along its length. The straightening mechanism 300 is positioned near the outlet holes 112 to prevent damage caused by straightening the wire in a coiled state before it is fully heated. The straightening mechanism 300 has a support line 500 on each side near the inlet holes 111 and the outlet holes 112. The support line 500 is fixed inside the housing 110 and has a threading hole 510 corresponding to the inlet holes 111 and the outlet holes 112. After entering the straightening space through the inlet hole 111, the wire passes through the support line 500, the straightening mechanism 300, and the support line 500 again, finally exiting through the outlet hole 112. The support lines 500 on the inlet and outlet sides of the straightening mechanism 300 support the soft wire (which softens easily after heating), preventing positional shift during transport and ensuring the straightening effect.

[0021] The straightening mechanism 300 includes a mounting plate 310, a sliding block 320, an elastic element 330, an adjusting knob 340, and a straightening wheel 350. The mounting plate 310 is fixedly connected to the housing 100. The mounting plate 310 has multiple guide portions 361, spaced apart along the length of the mounting plate 310 (i.e., the direction of wire movement, from the inlet hole 111 to the outlet hole 112). Multiple sliding blocks 320 and elastic elements 330 are provided. Each sliding block 320 is slidably connected to a guide portion 361. An elastic element 330 is provided between each sliding block 320 and the mounting plate 310, with both ends of the elastic element 330 abutting against the sliding block 320 and the mounting plate 310, respectively. A connecting portion 362 extends horizontally outward from the guide portion 361. The adjusting knob 340 is threaded onto the connecting portion 362 and passes downward through the connecting portion 362 to abut against the top surface of the sliding block 320. The straightening wheels 350 are arranged in multiple rows, which are alternately connected to the mounting plate 310 and the sliding block 320. Specifically, the straightening wheels 350 are divided into upper and lower rows. One end of the upper row of straightening wheels 350 is fixed to the sliding block 320, while the other end is suspended. The wheels on each row of straightening wheels 350 have the ability to rotate for straightening. In this embodiment, two straightening wheels 350 are mounted on one sliding block 320. The lower row of straightening wheels 350 is fixed to the mounting plate 310, and the upper and lower rows of straightening wheels 350 are arranged alternately. The arrangement of the straightening wheels 350 and the structure of each row of straightening wheels 350 are all existing conventional technologies and will not be described in detail.

[0022] The above-mentioned straightening mechanism 300 incorporates an elastic element 330 between each sliding block 320 and the mounting plate 310. The two ends of the elastic element 330 abut against the sliding block 320 and the mounting plate 310 respectively. The adjusting knob 340 directly abuts against the sliding block 320. Thus, the sliding block 320 remains stable under the action of the elastic element 330 and the adjusting knob 340. When adjusting the height of the sliding block 320 to adjust the distance between the upper and lower straightening wheels 350, to decrease the distance, rotate the adjusting knob 340 to press the sliding block 320 down; to increase the distance, rotate the adjusting knob 340 to move it up, causing the elastic element 330 to push the sliding block 320. The operation is simple, requiring only the rotation of the adjusting knob 340, reducing adjustment time and improving efficiency. The adjusting knob 340 is threaded onto the connecting part 362; the small thread pitch improves adjustment accuracy. The elastic element 330 can continuously press against the adjusting knob 340 through the sliding block 320, which can eliminate the backlash of the threaded pair, maintain the stability of the adjusted position, and enhance the self-locking reliability.

[0023] The mounting plate 310 has multiple first mounting slots 312, all with upward-facing openings and spaced apart along the length of the mounting plate 310. The straightening mechanism 300 also includes multiple guide blocks 360, each with one end connected to a first mounting slot 312 and the other end extending upwards from the first mounting slot 312 to form the aforementioned guide portion 361 and connecting portion 362. In this embodiment, the guide block 360 is specifically shaped like the number 7.

[0024] The sliding block 320 has a through hole 321 at the middle position, which extends vertically. During assembly, the bottom of the guide block 360 passes through the through hole 321 and is then installed in the first mounting groove 312. After assembly, the sliding block 320 can move up and down along the guide block 360. The upper part of the sliding block 320 is limited by the connecting part 362 to prevent it from moving out of the guide block 360 from above.

[0025] In this embodiment, the sliding block 320 is inverted U-shaped, and the mounting plate 310 has recessed grooves 311 at corresponding positions on both sides of the inverted U-shape. When the sliding block 320 moves to a lower position, both sides of the sliding block 320 can be inserted into the corresponding recessed grooves 311.

[0026] In this embodiment, the elastic element 330 is a spring. A first slot 322 is provided on each side of the bottom surface of the sliding block 320. A second slot 313 is provided on the mounting plate 310 at a position corresponding to the first slot 322. The elastic element 330 is engaged between each first slot 322 and its corresponding second slot 313. By providing the first slots 322 and second slots 313, the two ends of the spring are secured, facilitating assembly. Simultaneously, the slot walls can laterally limit the elastic element 330, preventing displacement or twisting during compression, ensuring uniform transmission of elastic force, stably supporting the sliding block 320, and improving position holding performance.

[0027] Before straightening the line, to facilitate threading, the upper and lower straightening wheels 350 need to be kept at a certain distance. Adjusting the height of the sliding block 320 by rotating the adjusting knob 340 requires many turns to move the sliding block 320 upward, resulting in slow operation. In this embodiment, the guide block 360 is slidably connected to the first mounting groove 312. When the upper straightening wheel 350 needs to be moved upward to thread the line, the guide block 360 is moved upward a certain distance. At this time, the bottom of the guide block 360 and the adjusting knob 340 mounted on the guide block 360 move upward. The sliding block 320 then moves upward a certain distance under the action of the elastic element 330 to facilitate threading. After threading, the guide block 360 is moved down to the initial position for subsequent line straightening.

[0028] The mounting plate 310 has a circular groove 314 on its side near the outer casing 100, which communicates with the first mounting groove 312. The bottom of the guide block 360 has a strip hole 363, which is arranged along the transverse diameter of the circular groove 314. The length of the strip hole 363 is adapted to the transverse diameter of the circular groove 314 so that the eccentric shaft 430 can move within the strip hole 363 when rotating. The strip hole 363 is arranged opposite to the circular groove 314. The guide block 360 is equipped with an eccentric wheel mechanism. The eccentric wheel mechanism 400 includes a disc 410 and a concentric shaft 420 and an eccentric shaft 430 respectively fixed on both sides of the disc 410. The disc 410 is rotatably disposed within the circular groove 314. The concentric shaft 420 is coaxially arranged with the disc 410, and the free end of the concentric shaft 420 extends out of the outer casing 100 for operation by the operator. The eccentric shaft 430 is eccentrically positioned relative to the disk 410, specifically at the edge of the disk 410. The free end of the eccentric shaft 430 extends into the slotted hole 363. When it is necessary to move the upper row of straightening rollers 350 upwards for threading, the operator rotates the free end of the concentric shaft 420. The disk 410 and the eccentric shaft 430 rotate, and the eccentric shaft 430 moves within the slotted hole 363, causing the guide block 360 to move upwards. This allows the upper row of straightening rollers 350 to be moved upwards quickly for threading. After threading, the concentric shaft 420 is rotated back to its initial position, and the upper row of straightening rollers 350 is moved back to its initial position.

[0029] The guide block 360 slides up and down in the first mounting groove 312. When the eccentric shaft 430 is inserted into the strip hole 363, the guide block 360 is installed in the first mounting groove 312.

[0030] Mounting plate 310 has a second mounting groove 315 on its side away from housing 100. The second mounting groove 315 communicates with the first mounting groove 312. A cover 316 is fixedly connected to the opening of the second mounting groove 315. A protrusion 3161 is provided on the side of the cover 316 near the first mounting groove 312. The protrusion 3161 has a vertically set limiting surface. The eccentric shaft 430 is limited and engaged with the limiting surface of the protrusion 3161. Specifically, the upper straightening wheel 350 is in the initial position. The eccentric shaft 430 and the cam 3161 are in a limiting engagement, and the upper straightening wheel 350 is in an upward position that facilitates threading. The eccentric shaft 430 and the cam 3161 are in a limiting engagement. Thus, when the operator rotates the concentric shaft 420, and the eccentric shaft 430 is limited by the limiting surface of the cam 3161, the operator knows that the upper straightening wheel 350 has rotated to the initial position / threading position, which facilitates operation.

[0031] To facilitate the operator's rotation of the concentric shaft 420, the eccentric wheel mechanism 400 also includes an external knob 440, which is fixedly connected to the free end of the concentric shaft 420.

[0032] The above description is only a preferred embodiment of the present utility model, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
