Abstract
Description
Technical Field
[0001] This utility model relates to the field of headphone ear clip processing technology, specifically a wearable headphone ear clip rolling device. Background Technology
[0002] The ear clip portion of wearable headphones (such as clip-on and ear-hook headphones) typically needs to possess good elasticity, fit, and comfort. Therefore, its manufacturing process may involve the rolling and forming of metal or polymer materials. Rolling equipment is used to process materials (such as shape memory metals, nickel-titanium shape memory alloys, etc.) into sheets or strips of specific thicknesses and shapes through a rolling process, which are then followed by stamping, bending, and other processes to form the ear clip.
[0003] In existing metal rolling equipment, the metal to be processed is placed between the pressure rollers, and the direction of the metal is controlled according to the pressure between the rollers and the rotation direction. This makes it easy for the position of the metal to shift during the extrusion process, resulting in uneven extrusion of the rolled part. This means that subsequent cutting and polishing work will be more complicated, affecting the practicality of the equipment. Optimization and improvement are needed. Utility Model Content

[0024] like Figure 1 - Figure 4 As shown, this application provides a wearable ear clip rolling device, including: a support plate 1, a connecting frame 2 is provided at the top of the support plate 1, and a power mechanism 3 is connected to one end of the connecting frame 2;
[0025] Specifically, such as Figure 2 As shown, the inner front end of the connecting frame 2 is connected to the pressure roller 4, and the inner rear end of the connecting frame 2 is connected to the guide roller 5. The pressure roller 4 is divided into two, which cooperate with each other to roll the metal material, and the guide roller 5 pulls out the rolled metal material.
[0026] The front end of the connecting frame 2 is provided with an import adjustment component, which includes a bottom baffle 6 and an upper limit baffle 7 at the top of the bottom baffle 6. The front end of the upper limit baffle 7 is provided with a movable adjustment block 9 and the top of the movable adjustment block 9 is provided with an upper pressure plate 13. The import adjustment component is used for guiding and limiting the adjustment of the processing material.
[0027] Specifically, such as Figure 3 As shown, the bottom baffle 6 is connected to the front of the connecting frame 2, and the upper limit baffle 7 is connected to the front top of the connecting frame 2. The bottom baffle 6 and the upper limit baffle 7 are used to limit the upper and lower ends of the metal material rolling, respectively.
[0028] Specifically, such as Figure 3As shown, the front end of the upper limit baffle 7 is connected to a guide crossbar 8, and the movable adjustment block 9 is located on the outside of the guide crossbar 8. The inner side of the movable adjustment block 9 is connected to a bidirectional threaded rod 10. By rotating the bidirectional threaded rod 10, the position of the movable adjustment block 9 can be adjusted on the outside of the guide crossbar 8 to accommodate the size of the processed material.
[0029] Specifically, such as Figure 4 As shown, the top of the movable adjusting block 9 is connected to an elastic connecting rod 11, and a stop block 12 is provided at the top of the elastic connecting rod 11. An upper pressure plate 13 is provided on the outside of the elastic connecting rod 11. The spring on the outside of the elastic connecting rod 11 is connected to the top of the upper pressure plate 13, which can elastically press the upper pressure plate 13 downward to limit the top of the processed material. The stop block 12 fixes the top of the spring of the elastic connecting rod 11.
[0030] The rear end of the connecting frame 2 is provided with an export protection component, which includes an export frame 14 and an adjustment plate 15 at the top of the export frame 14. A sliding frame 17 is connected to the outside of the adjustment plate 15. The export protection component is used for protection after material processing.
[0031] Specifically, such as Figure 4 As shown, the export frame 14 is connected to the rear end of the connecting frame 2, and the outer side of the export frame 14 is connected to the limit rod 16. The rear end of the export frame 14 is connected to the take-up roller 20, which can take up the rolled metal strip.
[0032] Specifically, such as Figure 4 As shown, the slide frame 17 is located on the outside of the limiting rod 16, and the top of the slide frame 17 is connected to the second elastic connecting rod 18. The slide frame 17 slides up and down on the outside of the limiting rod 16. The second elastic connecting rod 18 connected on the inner side has a certain elastic protection, which makes it easy to control the up and down position of the adjusting plate 15 according to the transmission pressure, thereby improving the tension adjustment of the winding transmission.
[0033] Specifically, such as Figure 4 As shown, a position control plate 19 is connected to the top of the adjustment plate 15, and there are two position control plates 19. The two position control plates 19 slide and adjust at the top of the adjustment plate 15 to adapt to the limiting transmission adjustment of the calendered material.
[0034] In this embodiment: during the feeding process, a bottom baffle 6 and an upper limit baffle 7 are set for limiting the position. The left and right positions are controlled by a bidirectional threaded rod 10. The upper pressure plate 13 is adjusted up and down to squeeze and limit the top of the material to ensure the stability of the transmission. When the calendered material is discharged, a winding roller 20 is set for winding. Two position control plates 19 are set at the discharge part for clamping and limiting to prevent the discharge position from deviating. Then, the adjustment plate 15 at the bottom can provide buffer protection by sliding the slide frame 17 up and down to avoid wear during the transmission process.
[0035] The specific solution is as follows: First, during the feeding process, the material is placed on the top of the bottom baffle 6 and conveyed into the connecting frame 2. The top is limited by the upper limit baffle 7. The left and right clamping positions of the moving adjustment block 9 are controlled by the bidirectional threaded rod 10. Then, the upper pressure plate 13, under the elastic connection of the elastic connecting rod 11, squeezes and limits the top of the material to ensure the stability of the transmission position. After being calendered by the pressure roller 4, the material is exported by the export roller 5 and then wound up by the winding roller 20. During export, the installation position of the two position control plates 19 at the top of the adjusting plate 15 is adjusted to clamp and limit the material to prevent the export position from deviating. Then, the adjusting plate 15 slides up and down under the connection of the sliding frame 17 to provide buffer protection, reduce the tension during material winding and transmission, reduce transmission wear, and ensure product quality.
