[0002] Titanium and titanium alloy sheets are commonly used in industry and aerospace, possessing advantages such as high strength and good corrosion resistance, making them a widely applied high-quality material. During the processing of titanium and titanium alloy sheets, unevenness can occur due to factors such as metal shavings or debris adhering to the roller surface or operator errors causing the sheet to not enter the rolling mill in the correct position. For titanium and titanium alloy sheets used in eyeglass frames, leveling is essential to improve wearing comfort, ensure the accuracy of the lens optical center, prevent frame deformation, and enhance the symmetry of the eyeglass frame. Therefore, improvements are necessary. Summary of the Invention

[0003] The technical problem solved by this utility model is to provide a leveling device for titanium and titanium alloy eyeglass frame plates. This device features rolling guide devices located inside a housing and fixed at their lower ends to the platform plate on the outer sides of the two long sides of the lower heating plate. These rolling guide devices provide rolling support and guidance along the edges of the eyeglass frame plates, ensuring the plates are properly aligned and positioned under the heat and pressure of the upper and lower heating plates. This avoids misalignment caused by improper manual operation, ensuring effective heating and leveling, and guaranteeing the flatness of the eyeglass frame plates. This, in turn, provides assurance for eyeglass wearing comfort, the accuracy of the lens optical center, and the symmetry of the eyeglass frame. The adjustable height of the upper heating plate accommodates the heating and leveling needs of plates with different thicknesses.

[0004] The technical solution adopted in this utility model is: a leveling device for titanium and titanium alloy eyeglass frame plates, including a platform frame and a feeding roller bracket and a discharging roller bracket respectively located on the left and right sides of the platform frame. A box and a lower heating plate located inside the box are fixed on the platform plate of the platform frame. Rolling guide devices for limiting and guiding the eyeglass frame plates are provided on the outer sides of the two long sides of the lower heating plate, located inside the box and fixed at the lower end to the platform plate of the platform frame. An upper heating plate is provided above the lower heating plate and connected to a height adjustment device fixed at the upper end to the top surface of the box, and the distance between the upper heating plate and the lower heating plate is adjusted by the height adjustment device.

[0005] The rolling guide device includes multiple rollers and two parallel guide plates arranged along the length of the platform frame. Multiple mounting grooves are evenly distributed along the length of the guide plates on their inner sidewalls. The rollers are adapted to and rotatably installed in the mounting grooves, and the contact guide portion between the rollers and the eyeglass frame plate is located outside the mounting groove.

[0006] Furthermore, the roller is a stepped column composed of a large-diameter section in the middle and small-diameter sections at the upper and lower ends of the large-diameter section, and the ends of the small-diameter sections at the upper and lower ends of the roller are hemispherical structures. A limiting plate for limiting the small-diameter sections of the roller is fixed on the inner side wall of the guide plate.

[0007] Furthermore, the mounting groove is shaped to fit the roller, and the cross-sectional shape of the groove walls at both ends of the mounting groove is a semi-circular structure.

[0008] Furthermore, the left and right side walls of the box are respectively provided with a feeding opening and a discharging opening, and the lower edge of the feeding opening and the discharging opening is not higher than the surface of the lower heating plate. The distance between the rollers on the outer side of the two long sides of the lower heating plate and the contact guide part of the eyeglass frame plate is less than the length of the feeding opening and the discharging opening.

[0009] Furthermore, the height adjustment device includes an electric cylinder, a guide rod, and a guide plate. The upper end of the electric cylinder is fixedly fixed to the top surface of the housing, and the lower end of the telescopic rod of the electric cylinder is fixedly connected to the middle of the upper surface of the upper heating plate. The upper and lower ends of the guide rod are respectively fixed to the top surface of the housing and the upper surface of the guide plate in the rolling guide device. The upper surface of the upper heating plate is fixed with an inverted L-shaped guide plate at each of the four corners. The through hole on the upper horizontal plate of the guide plate is fitted with the guide rod. A spring is fitted on the guide rod, with its lower end abutting against the upper surface of the guide plate and its upper end abutting against the bottom surface of the horizontal plate of the guide plate. Under the guidance of the guide plate and the guide rod, the electric cylinder drives the upper heating plate to move up and down, thereby adjusting the distance between the upper heating plate and the lower heating plate.

[0010] Furthermore, the box body has a door on its side wall along its length.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to Figures 1-2 in the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0018] It should be noted that, unless otherwise stated herein, the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In this document, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0020] A leveling device for titanium and titanium alloy eyeglass frame plates, as shown in Figures 1-2, includes a platform frame 1 and an infeed roller bracket 2 and an outlet roller bracket 3 respectively located on the left and right sides of the platform frame 1. The infeed roller bracket 2 is used to support the eyeglass frame plate model after surface impurity removal, while the outlet roller bracket 3 is used to support the leveled eyeglass frame plate. A housing 9 and a lower heating plate 4 located inside the housing 9 are fixed on the platform plate surface of the platform frame 1. Rolling guide devices for limiting and guiding the eyeglass frame plate are provided on the outer sides of the two long sides of the lower heating plate 4, located inside the housing 9 and fixed at the lower end to the platform plate surface of the platform frame 1. An upper heating plate 5 is provided above the lower heating plate 4 and connected to a height adjustment device fixed at the upper end to the top surface inside the housing 9. The distance between the upper heating plate 5 and the lower heating plate 4 is adjusted by the height adjustment device. In the above structure, a rolling guide device is provided on the outer side of the two long sides of the lower heating plate 4. The device is located inside the box 9 and its lower end is fixed to the platform plate of the platform frame 1. The rolling guide device guides the eyeglass frame plate by rolling support, thereby completing the alignment of the eyeglass frame plate. This ensures that the eyeglass frame plate is in the correct position for heating and flattening by the upper heating plate 5 and the lower heating plate 4, avoiding the eyeglass frame plate from tilting due to improper manual operation and ensuring the heating and leveling effect.

[0021] The upper heating plate 5 and the lower heating plate 4 have the same structure, both consisting of a groove-shaped pressure plate, a heating plate located inside the pressure plate, and a heat insulation plate fixed at the lower end of the pressure plate and in contact with the heating plate.

[0022] As shown in Figure 2, the specific structure of the rolling guide device is as follows: The rolling guide device includes multiple rollers 7 and two parallel guide plates 6 arranged along the length of the platform frame 1. Multiple mounting grooves 8 are evenly distributed along the length of the guide plates 6 on their inner sidewalls. The rollers 7 are adapted to and rotatably installed in the mounting grooves 8, and the rollers 7 are located outside the mounting grooves 8 when they contact the edge of the eyeglass frame. During the process of the eyeglass frame entering through the feed opening 14 on the left side wall of the box, the two sides of the eyeglass frame contact the rollers 7 on the same side respectively. Under the rolling action of the rollers 7, the eyeglass frame is guided to be in the correct position where it is heated and flattened by the upper heating plate 5 and the lower heating plate 4, thus avoiding the problem of the eyeglass frame being tilted due to improper manual operation.

[0023] The roller 7 is a stepped column consisting of a large-diameter section in the middle and small-diameter sections at the upper and lower ends of the large-diameter section. The ends of the small-diameter sections at the upper and lower ends of the roller 7 are hemispherical. A limiting plate 16 is fixed on the inner wall of the guide plate 6 to limit the position of the small-diameter sections of the roller 7. The function of the limiting plate 16 is to prevent the small-diameter sections of the roller 7 from falling out of the mounting groove 8, thereby ensuring the position of the ball 7. Furthermore, the fixing of the limiting plate 16 is based on the premise that it does not affect the normal up and down movement of the upper heating plate 5, so as to avoid interference with the upper heating plate 5. Specifically, the mounting groove 8 is a shape adapted to the roller 7, and the cross-sectional shape of the groove wall at the upper and lower ends of the mounting groove 8 is a semi-circular structure. Alternatively, a structure in which balls are set on the upper and lower end faces of the roller 7 can be used to realize the rotational installation of the roller 7 in the mounting groove 8.

[0024] The left and right side walls of the housing 9 are respectively provided with a feeding opening 14 and a discharging opening. The lower edge of the feeding opening 14 and the discharging opening is not higher than the upper surface of the lower heating plate 4. When the eyeglass frame plate enters or exits the housing 9, either the lower edge of the feeding opening 14 and the discharging opening cannot contact the eyeglass frame plate to avoid scratching the eyeglass frame plate, or the edges of the lower edge of the feeding opening 14 and the discharging opening are rounded to ensure that the lower edge is smooth and free of burrs. The distance between the rollers 7 on the outer side of the two long sides of the lower heating plate 4 and the contact guide part of the eyeglass frame plate is less than the length of the feeding opening 14 and the discharging opening. Moreover, the edges of the feeding opening 14 and the discharging opening in the width direction are rounded.

[0025] As shown in Figure 2, the specific structure of the height adjustment device is as follows: The height adjustment device includes an electric cylinder 10, a guide rod 12, and a guide plate 11. The upper end of the electric cylinder 10 is fixed in the center to the top surface inside the housing 9, and the lower end of the telescopic rod of the electric cylinder 10 is fixedly connected to the middle of the upper surface of the upper heating plate 5. The upper and lower ends of the guide rod 12 are respectively fixed to the top surface inside the housing 9 and the upper surface of the guide plate 6 in the rolling guide device. The upper surface of the upper heating plate 5 is fixed with guide plates 11 in an inverted L-shape at each of the four corners, and the upper end of the guide plate 11 is horizontal on the plate. The through hole and guide rod 12 are fitted together. A spring 13 is fitted on the guide rod 12, with its lower end abutting against the upper surface of the guide plate 6 and its upper end abutting against the bottom surface of the horizontal plate of the guide plate 11. Under the guidance of the guide plate 11 and the guide rod 12, the upper heating plate 5 is driven by the electric cylinder 10 to move up and down, thereby adjusting the distance between the upper heating plate 5 and the lower heating plate 4. The design of the above structure helps to reduce the overall height of the equipment, making the equipment structure compact. The box body 9 is provided with a box door 15 on its side wall along its length direction, which facilitates the maintenance and repair of the internal components of the box body 9.

[0026] In the above structure, the height adjustment device for adjusting the height of the upper heating plate 5 adopts a built-in design structure, which is located inside the housing 9. This helps to reduce the overall height of the equipment, making the equipment structure compact and meeting the requirements of miniaturization design.

[0027] To improve the leveling effect of the sheet material, a pair of upper and lower leveling rollers can be installed on the right end of the platform frame 1 for secondary leveling of the heated and leveled eyeglass frame sheet material. The upper or lower leveling rollers are driven by a motor, and the number of leveling rollers is set according to the specific usage requirements.

[0028] This technical solution features a simple structure and novel design. It eliminates the need for manual adjustment of the heated and flattened position of the sheet material, ensuring the flatness of the eyeglass frame sheet. This, in turn, guarantees the comfort of wearing the glasses, the accuracy of the optical center of the lenses, and the symmetry of the outer frame of the eyeglasses. The adjustable height of the upper heating plate installation structure can meet the heating and leveling requirements of sheet materials of different thicknesses.
