Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lens processing technology, and in particular relates to a drying machine for optical lens production. Background Technology
[0002] The processing of optical lenses typically includes steps such as roughing, grinding, core taking, coating, bonding, ink coating, and cutting. During the grinding, core taking, coating, bonding, and ink coating processes, the lens products need to be cleaned between processes to remove impurities generated during processing. After cleaning, the lenses are dried to improve the processing quality of subsequent processes.
[0003] Existing patent CN220304134U discloses a rapid drying device for optical lenses after cleaning. This invention provides a rapid drying device for optical lenses after cleaning, enabling uniform drying and preventing lens abrasion. The rapid drying device for optical lenses after cleaning includes a base, a support frame, an upper support bar, a motor, and an active rotating shaft. The support frame is connected to the upper side of the base, the upper support bar is connected to the upper part of the support frame, the motor is connected to the right side of the upper support bar, and the active rotating shaft is connected to the motor output shaft, rotatably connected to the upper support bar. This invention achieves uniform drying of optical lenses after cleaning by turning on the heater, generating heat from the heating wire, which is then blown into the outer spherical cover by a fan. The spherical nozzle then conducts the hot air to the grid clamps, achieving the effect of uniform drying and preventing lens abrasion. However, heating the external air to dry the optical lenses prolongs the drying process, increasing power consumption, reducing production efficiency, and raising production costs. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned technical problems by providing a drying machine for optical lens production. The heating chamber is equipped with a ventilation device to accelerate heat exchange within the heating chamber, which can significantly reduce the drying time of optical lenses and improve production efficiency.
[0005] In view of this, the present invention provides a drying machine for optical lens production, characterized in that it includes a frame, a heating chamber is provided inside the frame, and the heating chamber is provided with:
[0006] A heating device is installed on the side wall of a heating chamber, and the side wall of the heating chamber is provided with ventilation holes. The heating device is used to dry the surface of an optical lens.
[0007] A ventilation device is provided above the heating chamber to accelerate air circulation within the heating chamber.
[0008] A clamping device, one end of which is located at the bottom of the heating chamber, is used to fix the position of the optical lens in the heating chamber.
[0009] In this technical solution, the clamping device holds the optical lens inside the heating chamber, the heating device dries the optical lens, and the ventilation device is set above the heating device to introduce air into the heating chamber through the vent, thereby accelerating the flow of hot air in the heating chamber, reducing the drying time of the optical lens, and improving production efficiency.
[0010] Furthermore, multiple heating chambers are arranged along the length of the frame, and multiple sets of clamping devices are arranged in the heating chambers, with multiple optical lenses arranged on the clamping devices.
[0011] In this technical solution, the frame has multiple heating chambers, and each heating chamber is equipped with multiple sets of clamping devices. Each clamping device is equipped with multiple optical lenses, so that the heating device can heat multiple optical lenses simultaneously, thereby improving drying efficiency.
[0012] Furthermore, an insulation layer is provided on the outside of the heating chamber, the insulation layer is attached to the outer surface of the heating chamber, and the ventilation device is installed through the insulation layer and is sealed to the insulation layer.
[0013] In this technical solution, the insulation layer installed on the outside of the heating chamber can prevent heat exchange between the heating chamber and the outside, thus keeping the temperature inside the heating chamber stable, which is beneficial for heating the optical lens. The insulation layer between the ventilation device and the heating chamber can protect the ventilation device from damage. The ventilation device and the insulation layer are sealed together to prevent air from leaking out of the insulation layer and affecting the air circulation in the heating chamber.
[0014] Furthermore, heating grooves are provided on the side walls of both sides of the heating chamber, and the heating device includes infrared lamps. The infrared lamps are fixedly installed in the heating grooves along the height direction of the heating chamber. Multiple infrared lamps are provided, and the infrared lamps are used to dry the optical lenses.
[0015] In this technical solution, using infrared lamps to directly heat the optical lenses can reduce drying time compared to other heating devices that indirectly heat the optical lenses by heating the air. Infrared lamps installed on both sides of the heating chamber to dry the optical lenses are more efficient than single-sided heating, and dual-sided heating can prevent uneven heating in the heating chamber, which would affect the drying of the optical lenses.
[0016] Furthermore, the heating chamber has a double-layer structure along its length sidewalls. The heating chamber includes a main sidewall, an outer sidewall, and an inner sidewall. The two ends of the main sidewall are perpendicularly connected to the outer sidewall and the inner sidewall, respectively. The outer sidewall is fixedly connected to the insulation layer. There is a space between the outer sidewall and the inner sidewall for air circulation. The inner sidewall is provided with ventilation holes, and multiple ventilation holes are provided on both sides of the heating tank.
[0017] In this technical solution, a double-layer structure with an outer side wall and an inner side wall is provided only on the two side walls of the heating chamber, which is conducive to the ventilation device entering the heating chamber through the vent through the space between the outer side wall and the inner side wall.
[0018] Furthermore, the ventilation device includes an inlet component and an outlet component. The inlet component is disposed between an outer side wall and an inner side wall on one side, and the outlet component is disposed between an outer side wall and an inner side wall on the other side. The inlet component is used to discharge air into the heating chamber, and the outlet component is used to discharge air from the heating chamber.
[0019] Furthermore, the access component includes:
[0020] An air intake pipe is provided in the space between the outer side wall and the inner side wall. Multiple air intake pipes are provided. The air intake pipes are connected through the insulation layer. The diameter of the air intake pipe is smaller than the distance between the outer side wall and the inner side wall.
[0021] A connecting pipe is disposed above the heating chamber along the length of the heating chamber, and the connecting pipe is connected to multiple air inlet pipes;
[0022] An air intake fan is fixedly mounted on the frame and is fixedly connected to a connecting pipe.
[0023] In this technical solution, the intake fan starts working, drawing outside air into the connecting pipe. The air then enters the heating chamber through the intake pipe, thereby exchanging heat with the heating chamber.
[0024] Furthermore, the emission device includes:
[0025] An exhaust pipe is disposed in the space between the outer and inner sidewalls opposite to the intake pipe. Multiple exhaust pipes are provided, and each exhaust pipe penetrates the insulation layer. The diameter of the exhaust pipe is smaller than the distance between the outer and inner sidewalls.
[0026] A connecting pipe is disposed above the heating chamber along the length of the heating chamber, and the connecting pipe is connected to multiple exhaust pipes;
[0027] An exhaust fan is fixedly mounted on the frame and is fixedly connected to a connecting pipe.
[0028] In this technical solution, the exhaust fan starts working and draws in the hot air in the heating chamber. The hot air in the heating chamber is discharged to the outside through the exhaust pipe and the connecting pipe, so that the heat in the heating chamber is carried away and the circulation of hot air in the heating chamber is accelerated, thereby increasing the drying speed of the optical lens.
[0029] Furthermore, the clamping device includes:
[0030] A support frame is rotatably mounted at the bottom of the heating chamber. The support frame includes a main rod and fixed shafts. The main rod is rotatably mounted inside the heating chamber along the height direction of the heating chamber. The fixed shafts are laterally mounted on the main rod. Multiple fixed shafts are arranged in the axial direction of the main rod.
[0031] A fixing frame is fixedly mounted on a fixing shaft. Multiple sets of fixing frames are provided on the fixing shaft. The fixing frame includes hooks and connectors. The inner diameter of the hooks is adapted to the diameter of the fixing shaft. The connectors are fixedly mounted below the hooks and are used to fix the position of the optical lenses.
[0032] In this technical solution, the rotation of the support frame can drive the optical lenses on the fixed frame to rotate, so that multiple optical lenses can be heated evenly in the heating chamber, preventing the optical lenses from being overheated and deformed.
[0033] Furthermore, the hook is made of elastic material, the connector is in the shape of a "∩", the distance between the two sides of the connector is adapted to the diameter of the optical lens, and the connector is vertically connected to the optical lens.
[0034] In this technical solution, the hook is made of elastic material so that it can be locked onto the fixed shaft to prevent the connector from shifting during rotation. The distance between the two sides of the connector is adapted to the diameter of the optical lens so that the connector can fix the position of the optical lens. The vertical connection between the connector and the optical lens allows the surface of the optical lens to be dried without having to turn it over during the drying process, thus saving drying steps.
[0035] The beneficial effects of this utility model are:
[0036] 1. This utility model uses infrared lamps to directly heat the optical lenses, which reduces drying time compared to other heating devices that indirectly heat the lenses by heating the air. Infrared lamps installed on both sides of the heating chamber are more efficient than single-sided heating, and dual-sided heating prevents uneven heating within the chamber, thus ensuring proper drying. The exhaust fan draws in hot air from the heating chamber, which is then discharged to the outside through the exhaust pipe. This process removes heat from the heating chamber and accelerates airflow, thereby increasing the drying speed of the optical lenses. Attached Figure Description
